MAINTENANCE
1.0

Introduction
This chapter of the manual describes:

2.0

•

preventive maintenance

•

safe handling of CMOS devices

•

repair procedures and techniques

Preventive Maintenance
The radios do not require a scheduled preventive maintenance program; however, periodic visual
inspection and cleaning is recommended.

2.1

Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches
are functional. We recommend against inspecting the interior electronic circuitry.

2.2

Cleaning
The following procedures describe the recommended cleaning agents and the methods to be used
when cleaning the external and internal surfaces of the radio. External surfaces include the front
cover, housing assembly, and battery case. These surfaces should be cleaned whenever a periodic
visual inspection reveals the presence of smudges, grease, and/or grime.

2.2.1

CAUTION

The effects of certain chemicals and their vapors can have harmful results on certain
plastics. Do not use aerosol sprays, tuner cleaners, and other chemicals to clean the
radio.

NOTE

Internal surfaces should be cleaned only when the radio is disassembled for servicing or
repair.

Cleaning External Plastic Surfaces
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild
dishwashing detergent in water. Apply this solution sparingly on the surface with a stiff, non-metallic,
short-bristled brush to work all loose dirt out. Use a soft, absorbent, lintless cloth or tissue to remove
the solution. Then dry the radio. Make sure that no water remains entrapped near the connectors,
cracks, or crevices.

6881091C63-A

Chapter 1: 2-2

2.2.2

Safe Handling of CMOS and LDMOS

Cleaning Internal Circuit Boards and Components
The only factory-recommended liquid for cleaning the printed circuit boards and their components is
isopropyl alcohol (100% by volume). Apply Isopropyl alcohol with a stiff, non-metallic, short-bristled
brush to dislodge embedded or caked materials located in hard-to-reach areas. The brush stroke
should direct the dislodged material out and away from the inside of the radio. Make sure that
controls or tunable components are not soaked with alcohol. Do not use high-pressure air to hasten
the drying process since this could cause the liquid to collect in unwanted places. Upon completion
of the cleaning process, use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply
any isopropyl alcohol to the frame, front cover, or back cover.
Always use a fresh supply of alcohol and a clean container to prevent contamination by
dissolved material (from previous usage).

NOTE

3.0

Safe Handling of CMOS and LDMOS
Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios. CMOS
characteristics make them susceptible to damage by electrostatic or high voltage charges. Damage
can be latent, resulting in failures occurring weeks or months later. Therefore, take special
precautions to prevent device damage during disassembly, troubleshooting, and repair.
CAUTION

DO NOT attempt to disassemble the radio without first referring to the disassembly and
reassembly sections in the Basic Service Manual (Motorola Publication part number
6881091C62 [CDM Series models] or 6881092C71 [PRO Series models]).

Handling precautions are mandatory for CMOS circuits and are especially important in low humidity
conditions.

4.0

General Repair Procedures and Techniques

4.1

Parts Replacement and Substitution
When replacing damaged parts, use identical part replacements. If an identical replacement
component is not locally available, check the parts list for the proper Motorola part number and order
the component from the nearest Motorola parts center (see the Appendix at the back of this manual).

4.2

Rigid Circuit Boards
This family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not
accessible, some special considerations are required when soldering and desoldering components.
The through-plated holes may interconnect multiple layers of the printed circuit. Therefore, exercise
care to avoid pulling the plated circuit out of the hole.
When soldering near the 18-pin and 40-pin connectors:
•

avoid accidentally getting solder in the connector.

•

be careful not to form solder bridges between the connector pins.

•

closely examine your work for shorts due to solder bridges.

6881091C63-A

General Repair Procedures and Techniques

4.3

Chapter 1: 2-3

Chip Components
Use either the RLN4062 Hot-Air Repair Station or the Motorola 0180381B45 Repair Station for chip
component replacement. When using the 0180381B45 Repair Station, select the TJ-65 minithermojet hand piece. On either unit, adjust the temperature control to 370°C (700°F), and adjust the
airflow to a minimum setting. Airflow can vary due to component density.
To remove a chip component:
1.

Use a hot-air hand piece and position the nozzle of the hand piece approximately 0.3 cm
(1⁄8") above the component to be removed.

2.

Begin applying the hot air. Once the solder reflows, remove the component using a pair of
tweezers.

3.

Using a solder wick and a soldering iron or a power desoldering station, remove the excess
solder from the pads.

To replace a chip component using a soldering iron:
1.

Select the appropriate micro-tipped soldering iron and apply fresh solder to one of the solder
pads.

2.

Using a pair of tweezers, position the new chip component in place while heating the fresh
solder.

3.

Once solder wicks onto the new component, remove the heat from the solder.

4.

Heat the remaining pad with the soldering iron and apply solder until it wicks to the
component. If necessary, touch up the first side. All solder joints should be smooth and shiny.

To replace a chip component using hot air:

4.4

1.

Use the hot-air hand piece and reflow the solder on the solder pads to smooth it.

2.

Apply a drop of solder paste flux to each pad.

3.

Using a pair of tweezers, position the new component in place.

4.

Position the hot-air hand piece approximately 0.3 cm (1/8") above the component and begin
applying heat.

5.

Once the solder wicks to the component, remove the heat and inspect the repair. All joints
should be smooth and shiny.

Shields
Remove and replace shields using the R1070 station with the temperature control set to
approximately 215°C (415°F) [230°C (445°F) maximum].
To remove the shield:
1.

Place the circuit board in the R1070 circuit board holder.

2.

Select the proper heat focus head and attach it to the heater chimney.

3.

Add solder paste flux around the base of the shield.

4.

Position the shield under the heat-focus head.

5.

Lower the vacuum tip and attach it to the shield by turning on the vacuum pump.

6.

Lower the focus head until it is approximately 0.3 cm (1/8") above the shield.

7.

Turn on the heater and wait until the shield lifts off the circuit board.

8.

Once the shield is off, turn off the heat, grab the part with a pair of tweezers, and turn off the
vacuum pump.

9.

Remove the circuit board from the R1070 circuit-board holder.
6881091C63-A

Chapter 1: 2-4

Notes For All Schematics and Circuit Boards

To replace the shield:

5.0

1.

Add solder to the shield, if necessary, using a micro-tipped soldering iron.

2.

Rub the soldering iron tip along the edge of the shield to smooth out any excess solder. Use
solder wick and a soldering iron to remove excess solder from the solder pads on the circuit
board.

3.

Place the circuit board back in the R1070 circuit board holder.

4.

Place the shield on the circuit board using a pair of tweezers.

5.

Position the heat-focus head over the shield and lower it to approximately 0.3 cm (1/8") above
the shield.

6.

Turn on the heater and wait for the solder to reflow.

7.

Once complete, turn off the heat, raise the heat-focus head, and wait approximately one
minute for the part to cool.

8.

Remove the circuit board and inspect the repair. No cleaning should be necessary.

THEORY OF OPERATION
1.0

Introduction
This chapter provides a detailed theory of operation for the control head circuits. For troubleshooting
information, refer to the related section of this manual.
NOTE From this point on the microprocessor is referred to as “µP”.

2.0

Control Head (CDM750 / PRO3100)

2.1

Power Supplies
The power supply to the control head is taken from the host radio’s FLT A+ voltage via connector
J0801, pin 3 and the regulated 5V via connector J0801 pin 7. The voltage FLT A+ is at battery level
and is used for the LEDs, the back light and to power up the radio using the On/Off/Volume knob.
The stabilized 5V is used for the µP and the keypad buttons. The voltage USW 5V derived from the
FLT A+ voltage and stabilized by the series combination of R0822, VR0822 is used to buffer the
internal RAM of the µP (U0831). C0822 allows the battery voltage to be disconnected for a couple of
seconds without losing RAM parameters. Dual diode D0822 prevents radio circuits from discharging
this capacitor. When the supply voltage is applied to the radio, C0822 is charged via R0822 and
D0822. To avoid the µP entering the wrong mode if the radio is switched on while the voltage across
C0822 is still too low, the regulated 5V supply charges C0822 via diode D0822.

2.2

Power On/Off
The On/Off/Volume knob, when pressed, switches the radio’s voltage regulators on by connecting
line ON OFF CONTROL to line UNSW 5V via D0821. Additionally, 5V at the base of digital transistor
Q0822 informs the control head’s µP about the pressed knob. The µP asserts pin 62 and line CH
REQUEST low to hold the line ON OFF CONTROL at 5V via Q0823 and D0821. The high line ON
OFF CONTROL also informs the host radio that the control head’s µP wants to send data via the
SBEP bus. When the radio returns a data request message, the µP informs the radio about the
pressed knob. If the radio is switched off, the radio’s µP switches it on and vice versa. If the On/Off/
Volume knob is pressed while the radio is on, the software detects a low state on line ON OFF
SENSE, the radio is alerted via line ON OFF CONTROL and sends a data request message. The
control head µP informs the radio about the pressed knob and the radio’s µP switches the radio off.

2.3

Microprocessor Circuit
The control head uses the Motorola 68HC11E9 µP (U0831) to control the LEDs and to communicate
with the host radio. RAM and ROM are contained within the µP.
The µP generates its clock using the oscillator inside the µP along with a 8 MHz ceramic resonator
(U0833) and R0920.
The µP’s RAM is always powered to maintain parameters such as the last operating mode. This is
achieved by maintaining 5V at µP, pin 25. Under normal conditions, when the radio is off, USW 5V is
formed by FLT A+ running to D0822. Capacitor C0822 allows the battery voltage to be disconnected

6881091C63-A

Chapter 2: 2-2

Control Head (CDM750 / PRO3100)

for a couple of seconds without losing RAM parameters. Diode D0822 prevents radio circuits from
discharging this capacitor.
There are eight analog-to-digital converter ports (A/D) on the µP. They are labeled within the device
block as PE0-PE7. These lines sense the voltage level ranging from 0 to 5V of the input line and
convert that level to a number ranging from 0 to 255 which can be read by the software to take
appropriate action.
Pin VRH is the high reference voltage for the A/D ports on the µP. If this voltage is lower than 5V the
A/D reading is incorrect. The VRL signal is the low reference for the A/D ports. This line is normally
tied to ground. If this line is not connected to ground, the A/D readings could be incorrect.
The µP determines the used keypad type and the control head ID by reading the levels at ports PC0
– PC7. Connections JU0852/3/4 are provided by the individual keypads.
The MODB / MODA input of the µP must be at a logic “1” to start executing correctly. The XIRQ and
the IRQ pins should also be at a logic “1”.
Voltage sense device U0832 provides a reset output that goes to 0V if the regulated 5V goes below
4.5 V. This is used to reset the controller to prevent improper operation.

2.4

SBEP Serial Interface
The host radio (master) communicates to the control head µP (slave) through its SBEP bus. This
bus uses only line BUS+ for data transfer. The line is bi-directional, that is, either the radio or the
control head µP can drive the line. The µP sends serial data via pin 50 and D0831 and it reads serial
data via pin 47. Whenever the µP detects activity on the BUS+ line, it starts communication.
When the host radio needs to communicate to the control head µP, it sends data via line BUS+. Any
transition on this line generates an interrupt and the µP starts communication. The host radio may
send data (for example, LED and back light status) or it may request the control head ID or the
keypad ID.
When the control head µP wants to communicate to the host radio, the µP brings the request line
CH REQUEST to a logic “0” via µP pin 62. This switches Q0823 on, which pulls line ON OFF
CONTROL high through diode D0821. A low-to-high transition on this line informs the radio that the
control head requires service. The host radio then sends a data request message via BUS+ and the
control head µP replies with the data it wants to send (for example, which key has been pressed or
that the volume knob has been rotated).
The control head µP monitors all messages sent via BUS+, but ignores any data communication
between the host radio and the CPS or the universal tuner.

2.5

Keypad Keys
The control head keypad is a six-key design. All keys are configured as two analog lines read by µP
pins 13 and 15. The voltage on the analog lines varies between 0V and 5V depending on which key
is pressed. If no key is pressed, the voltage at both lines is 5V. The key configuration can be thought
of as a matrix where the two lines represent one row and one column. Each line is connected to a
resistive divider powered by 5V. If a button is pressed, it will connect one specific resistor of each
divider line to ground level and thereby reduce the voltages on the analog lines The voltages of the
lines are A/D converted inside the µP (ports PE 0 - 1) and specify the pressed button. To determine
which key is pressed, the voltage of both lines must be considered.
An additional pair of analog lines and A/D µP ports (PE 3 – 2) are available to support a keypad
microphone, connected to the microphone connector J0811. Any microphone key press is
processed the same way as a key press on a control head.

Control Head (CDM750 / PRO3100)

2.6

Chapter 2: 2-3

Status LED and Back Light Circuit
All indicator LEDs (red, yellow, and green) are driven by current sources. To change the LED status
the host radio sends a data message via SBEP bus to the control head µP. The control head µP
determines the LED status from the received message and switches the LEDs on or off via port PB
7 – 0 and port PA4. The LED status is stored in the µP’s memory. The LED current is determined by
the resistor at the emitter of the respective current source transistor.
The back light for the keypad is controlled by the host radio the same way as the indicator LEDs
using µP port PA 5. The µP can switch the back light on and off under software control. The back
light current for the keypad is drawn from the FLT A+ source and controlled by two current sources.
The LED current is determined by the resistor at the emitter of the respective current source
transistor.

2.7

Microphone Connector Signals
Signals BUS+, PTT IRDEC, HOOK, MIC, HANDSET AUDIO, FLT A+, 5V, and two A/D converter
inputs are available at the microphone connector J0811. Signal BUS+ (J0811-7) connects to the
SBEP bus for communication with the CPS or the Universal Tuner. Line MIC (J0811-5) feeds the
audio from the microphone to the radio’s controller via connector J0801-4. The Line HANDSET
AUDIO (J0811-8) feeds the receiver audio from the controller (J0801-6) to a connected handset.
FLT A+, which is at supply voltage level, and 5V are used to supply any connected accessory like a
microphone or a handset.
The two A/D converter inputs (J0811-9/10) are used for a microphone with keypad. A pressed key
changes the DC voltage on both lines. The voltages depend on which key is pressed. The µP
determines from the voltage on these lines which key is pressed and sends the information to the
host radio.
Line PTT IRDEC (J0811-6) is used to key up the radio’s transmitter. While the PTT button on a
connected microphone is released, line PTT IRDEC is pulled to 5V level by R0843. Transistor
Q0843 is switched on and causes a low at µP port PA2. When the PTT button is pressed, signal PTT
IRDEC is pulled to ground level. This switches Q0843 off and the resulting high level at µP port PA2
signals the µP about the pressed PTT button. The µP signals the host radio about any status
change on the PTT IRDEC line via SBEP bus.
When the line PTT IRDEC is connected to FLT A+ level, transistor Q0821 is switched on through
diode VR0821 and thereby pulls the level on line ON OFF CONTROL to FLT A+ level. This switches
on the radio and puts the radio’s µP in bootstrap mode. Bootstrap mode loads the firmware into the
radio’s flash memory.
When the microphone’s hang-up switch is engaged, the HOOK input (J0811-3) signals the µP.
Depending on how the radio is programmed using the Customer Programming Software (CPS), the
µP may take actions such as turning the audio PA on or off. While the hang-up switch is open,
R0841 pulls the line HOOK to a 5V level. Transistor Q0841 is switched on and causes a low at µP
port PA1. When the HOOK switch is closed, the HOOK signal is pulled to ground level. This
switches R0841 off and the resulting high level at µP port PA1 signals the µP about the closed hangup switch. The µP signals the host radio about any status change on the HOOK line via the SBEP
bus.

2.8

Speaker
The control head contains a speaker for the receiver audio. The receiver audio signal from the
differential audio output of the audio amplifier, located on the radio’s controller, is fed via connector
J0801-10, 11 to the speaker connector P0801, pins 1 and 2. The speaker is connected to the

6881091C63-A

Chapter 2: 2-4

Control Head (CDM1250 / PRO5100 / CDM1550 Series / PRO7100)

speaker connector P0801. The control head speaker can be disconnected only if an external
speaker (connected through the accessory connector) is used.

2.9

Electrostatic Transient Protection
Electrostatic transient protection is provided for the sensitive components in the control head by
diodes VR0811, VR00812, and VR0816 - VR0817. The diodes limit any transient voltages. The
associated capacitors provide radio frequency interference (RFI) protection.

3.0

Control Head (CDM1250 / PRO5100 / CDM1550 Series / PRO7100)

3.1

Power Supplies
The power supply to the control head is taken from the host radio’s FLT A+ voltage via connector
J0801 pin 3 and the regulated 5V via connector J0801 pin 7. The voltage FLT A+ is at battery level
and is used for the LEDs, the back light and to power up the radio using the On/Off/Volume knob.
The stabilized 5V is used for the µP, the display, the display driver and the keypad buttons. The
voltage USW 5V derived from the FLT A+ voltage and stabilized by the series combination of R0822,
VR0822 is used to buffer the internal RAM of the µP (U0831). C0822 allows the battery voltage to be
disconnected for a couple of seconds without losing RAM parameters. Dual diode D0822 prevents
radio circuitry from discharging this capacitor. When the supply voltage is applied to the radio, C0822
is charged via R0822 and D0822. To avoid the µP entering the wrong mode when the radio is
switched on while the voltage across C0822 is still too low, the regulated 5V supply charges C0822
via diode D0822.

3.2

Power On/Off
The On/Off/Volume knob, when pressed, switches the radio’s voltage regulators on by connecting
line ON OFF CONTROL to line UNSW 5V via D0821. Additionally, 5V at the base of digital transistor
Q0822 signals the control head’s µP about the pressed knob. The µP asserts pin 62 and line CH
REQUEST low to hold line ON OFF CONTROL at 5V via Q0823 and D0821. The high line ON OFF
CONTROL also informs the host radio that the control head’s µP wants to send data via SBEP bus.
When the radio returns a data request message, the µP will inform the radio about the pressed knob.
If the radio was switched off, the radio’s µP will switch it on and vice versa. If the On/Off/Volume knob
is pressed while the radio is on, the software detects a low state on line ON OFF SENSE, the radio is
alerted via line ON OFF CONTROL, and sends a data request message. The control head µP will
inform the radio about the pressed knob and the radio’s µP will switch the radio off.

3.3

Microprocessor Circuit
The control head uses the Motorola 68HC11E9 µP (U0831) to control the LEDs and the LCD and to
communicate with the host radio. RAM and ROM are contained within the µP itself.
The µP generates its clock using the oscillator inside the µP along with a 8 MHz ceramic resonator
(U0833) and R0920.
The µP’s RAM is always powered to maintain parameters such as the last operating mode. This is
achieved by maintaining 5V at µP pin 25. Under normal conditions, when the radio is off, USW 5V is
formed by FLT A+ running to D0822. C0822 allows the battery voltage to be disconnected for a
couple of seconds without losing RAM parameters. Diode D0822 prevents radio circuitry from
discharging this capacitor.
There are eight analog-to-digital converter ports (A/D) on the µP. They are labeled within the device
block as PE0-PE7. These lines sense the voltage level ranging from 0 to 5V of the input line and

6881091C63-A

Chapter 2: 2-5

convert that level to a number ranging from 0 to 255 which can be read by the software to take
appropriate action.
Pin VRH is the high-reference voltage for the A/D ports on the µP. If this voltage is lower than 5V, the
A/D readings will be incorrect. Likewise pin VRL is the low reference for the A/D ports. This line is
normally tied to ground. If this line is not connected to ground, the A/D readings will be incorrect.
The µP can determine the keypad type and the control head ID by reading the levels at ports PC0 –
PC7. Connections JU0852/3/4 are provided by individual keypads.
The MODB / MODA input of the µP must be at a logic “1” for it to start executing correctly. The XIRQ
and the IRQ pins should also be at a logic “1”.
Voltage sense device U0832 provides a reset output that goes to 0V if the regulated 5V goes below
4.5 V. This is used to reset the controller to prevent improper operation.

3.4

SBEP Serial Interface
The host radio (master) communicates to the control head µP (slave) through its SBEP bus. This
bus uses only line BUS+ for data transfer. The line is bi-directional, that is, either the radio or the
control head µP can drive the line. The µP sends serial data via pin 50 and D0831 and it reads serial
data via pin 47. Whenever the µP detects activity on the BUS+ line, it starts communication.
When the host radio needs to communicate to the control head µP, it sends data via line BUS+. Any
transition on this line generates an interrupt and the µP starts communication. The host radio may
send data (for example, display information, LED status, or back light status), or it may request the
control head or keypad ID.
When the control head µP wants to communicate to the host radio, the µP brings request line CH
REQUEST to a logic “0” via µP pin 62. This switches on Q0823, which pulls line ON OFF CONTROL
high through diode D0821. A low-to-high transition on this line informs the radio that the control
head requires service. The host radio then sends a data request message via BUS+ and the control
head µP replies with the data it wants to send (for example, which key has been pressed or that the
volume knob has been rotated).
The control head µP monitors all messages sent via BUS+, but ignores any data communication
between host radio and CPS or Universal Tuner.

3.5

Keypad Keys
The control head keypad is a six-key keypad (Model B) or a 10-key keypad (Model C). All keys are
configured as two analog lines read by µP pins 13 and 15. The voltage on the analog lines varies
between 0V and 5V depending on the key that has been pressed. If no key is pressed, the voltage at
both lines will be 5V. The key configuration can be thought of as a matrix where the two lines
represent one row and one column. Each line is connected to a resistive divider powered by 5V. If a
button is pressed, it will connect one specific resistor of each divider line to ground level and thereby
reduce the voltages on the analog lines. The voltages of the lines are A/D converted inside the µP
(ports PE 0 - 1) and specify the pressed button. The voltage of both lines must be considered in
order to determine which key is pressed.
An additional pair of analog lines and A/D µP ports (PE 3 – 2) is available to support a keypad
microphone, connected to the microphone connector J0811. Any microphone key press is
processed in the same way as a key press on the control head.

3.6

Control Head (CDM1250 / PRO5100 / CDM1550 Series / PRO7100)

Status LED and Back Light Circuit
All indicator LEDs (red, yellow, and green) are driven by current sources. To change the LED status
the host radio sends a data message via SBEP bus to the control head µP. The control head µP
determines the LED status based the received message and switches the LEDs on or off via port PB
7 – 0 and port PA4. The LED status is stored in the µP’s memory. The LED current is determined by
the resistor at the emitter of the respective current source transistor.
The back light for the LCD and the keypad is controlled by the host radio the same way as the
indicator LEDs using µP port PA 5. This port is a Pulse Width Modulator (PWM) output. The output
signal charges capacitor C0843 through R0847. By changing the pulse width under software control,
the DC voltage of C0843 and, therefore, the brightness of the back light can be changed in four
steps. The keypad back light current is drawn from the FLT A+ source and controlled by transistor
Q0933. The current flowing through the LEDs causes a proportional voltage drop across the parallel
resistors R0947 and R0948. This voltage drop is amplified by the op-amp U0931-2. U0931-2 and
Q0934 form a differential amplifier. The voltage difference between the base of Q0934 and the
output of U0931-2 determines the current from the base of the LED control transistor Q0933 and in
turn the brightness of the LEDs. The µP can control the LEDs by changing the DC level at the base
of Q0934. If the base of Q0934 is at ground level, Q0934 is switched off and no current flows
through Q0933 and the LEDs. If the base voltage of Q0934 rises, a current flows through Q0934
and in turn through Q0933, causing the LEDs to turn on and a rising voltage drop across R0947 and
R0948. The rising voltage causes the output of the op-amp to rise and to reduce the base to emitter
voltage of Q0934. This decreases the current of Q0933 until the loop has settled.

3.7

Liquid Crystal Display (LCD)
The LCD H0971 uses the display driver U0971. The display is a single-layer super-twist nematic
(STN) LCD display. It has 14 characters and a 5x8 dot matrix to display alphanumerical information
and a line with 21 pre-defined icons above the dot matrix.
The driver contains a data interface to the µP, an LCD segment driver, an LCD power circuit, an
oscillator, data RAM and control logic. At power up, the driver’s control logic is reset by a logic “0” at
input SR2 (U0971-15). The driver’s internal oscillator is set to about 20 kHz and can be measured at
pin 22. The driver’s µP interface is configured to accept 8-bit parallel data input (U0971-D0-D7) from
the control head µP (U0831 port PC0-PC7).
To write data to the driver’s RAM, the µP sets chip select (U0971-20) to logic “0” via U0831-11, RD
(U0971-18) to logic “1” via (U0831-10) and WR (U0971-17) to logic “0” via U0831-9. With input A0
(U0971-21) set to logic “0” via U0831-12, the µP writes control data to the driver. Control data
includes the RAM start address for the display data. With input A0 set to logic “1”, the µP then writes
the display data to the display RAM. When data transfer is complete, the µP terminates the chip
select, RD and WD activities.
The display driver’s power circuit provides the voltage supply for the display. This circuit consists of
a voltage multiplier, voltage regulator and a voltage follower. The external capacitors C0971 - C0973
configure the multiplier to double the supply voltage. In this configuration, the multiplier output VOUT
(U0971-8) supplies a voltage of –5V (2* –5V below VDD). The multiplied voltage VOUT is sent to
the internal voltage regulator. To set the voltage level of the regulator output V5 (U0971-5), this
voltage is divided by the resistors R0973 and R0974 and then fed back to the reference input VR
(U0971-6). In addition, the regulator output voltage V5 can be controlled electronically by a control
command sent to the driver. With the used configuration, the voltage V5 is about –2V. The voltage
V5 is resistively divided by the driver’s voltage follower to provide the voltages V1 - V4. These
voltages are required to drive the liquid crystals. The level of V5 can be measured by one of the µP’s
analog-to-digital converters (U0831-20) via resistive divider R0975, R0976. To stabilize the display
brightness over a large temperature range, the µP measures the temperature via analog-to-digital

6881091C63-A

Chapter 2: 2-7

converter (U0831-18) using temperature sensor U0834. Based on the measured temperature, the
µP adjusts the driver output voltage V5, and in turn the display brightness, via a parallel interface.

3.8

Microphone Connector Signals
Signals BUS+, PTT IRDEC, HOOK, MIC, HANDSET AUDIO, FLT A+, 5V and 2 A/D converter inputs
are available at the microphone connector J0811. Signal BUS+ (J0811-7) connects to the SBEP bus
for communication with the CPS or the Universal Tuner. Line MIC (J0811-5) feeds the audio from
the microphone to the radio’s controller via connector J0801-4. Line HANDSET AUDIO (J0811-8)
feeds the receiver audio from the controller (J0801-6) to a connected handset. FLT A+, which is at
supply voltage level, and 5V are used to supply accessories connected to the radio, if any (for
example, a microphone or a handset).
The two A/D converter inputs (J0811-9/10) are used for a microphone with a keypad. When a key is
pressed, the DC voltage changes on both lines. The voltages depend on which key is pressed. The
µP determines which key is pressed based on the voltage on these lines. It then sends the
information to the host radio.
Line PTT IRDEC (J0811-6) is used to key up the radio’s transmitter. When the PTT button on a
connected microphone is released, line PTT IRDEC is pulled to 5V level by R0843. Transistor
Q0843 is switched on and causes a low at µP port PA2. When the PTT button is pressed, signal PTT
IRDEC is pulled to ground level. This switches Q0843 off and the resulting high level at µP port PA2
signals the µP about the pressed PTT button. The µP informs the host radio about any change of
status on the PTT IRDEC line via SBEP bus.
When line PTT IRDEC is connected to FLT A+ level, transistor Q0821 is switched on through diode
VR0821 and thereby pulls the level on line ON OFF CONTROL to FLT A+ level. This switches the
radio on and puts the radio’s µP in bootstrap mode. Bootstrap mode is the mode used to load the
firmware into the radio’s flash memory (see the Controller chapter for more details).
The HOOK input (J0811-3) is used to signal the µP when the microphone’s hang-up switch is
engaged. Depending on the CPS programming the µP may take actions like turning the audio PA on
or off. While the hang-up switch is open, line HOOK is pulled to 5V level by R0841. Transistor
Q0841 is switched on and causes a low at µP port PA1. When the HOOK switch is closed, signal
HOOK is pulled to ground level. This switches off R0841 and the resulting high level at µP port PA1
informs the µP about the closed hang-up switch. The µP will inform the host radio about any status
change on the HOOK line via SBEP bus.

3.9

Speaker
The control head contains a speaker for receiver audio. The receiver audio signal from the
differential audio output of the audio amplifier (located on the radio’s controller) is fed via connector
J0801-10, 11 to the speaker connector P0801 pin 1 and pin 2. The speaker is connected to the
speaker connector P0801. The control head speaker can be disconnected if an external speaker
(connected through the accessory connector) is used.

3.10

Electrostatic Transient Protection
Electrostatic transient protection is provided for the sensitive components in the control head by
diodes VR0811, VR00812, and VR0816 - VR0817. The diodes limit any transient voltages to
tolerable levels. The associated capacitors provide Radio Frequency Interference (RFI) protection.

PassPort Trunking Controller Board (PTCB)
PassPort is an enhanced trunking protocol developed by Trident Microsystems that supports widearea dispatch networking. A network is formed by linking several trunked sites together to form a
single system. This offers users an extended communication coverage area. Additionally, users with
PassPort can seamlessly roam among all sites within the network. Seamless roaming means that
the radio user does not have to manually change the position on the radio when roaming from site to
site.
For models which feature PassPort Trunking operation, the PassPort Trunking Controller Board
(PTCB) is added to the top cover of the radio. This board also provides advanced voice storage
features. Refer to Figure 2-1 for connector and signal routing from and to the radio and PTCB.

Reference designators with an asterisk indicate
components that are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced
in the field will be off frequency at temperature
extremes.

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Chapters 4 - 13. Boards
are not orderable using the 84-prefixed number.

because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.

Controller Circuits

1.1

Overview
This section provides a detailed theory of operation for the radio and its components. The main radio
is a single-board design, consisting of the transmitter, receiver, and controller circuits. The main
board is designed to accept one option board. The option board may provide functions such as
secure voice/data, voice storage, or signaling decoder.
A control head is either mounted directly or connected by an extension cable. The control head
contains LED indicators, a microphone connector, buttons, and—depending on the radio type—a
display and a speaker. These provide the user with interface control over the various features of the
radio.
If no control head is mounted directly on the front of the radio, an expansion board containing
circuitry for special applications can be mounted on the front of the radio. An additional control head
can be connected by an extension cable.
In addition to the power cable and antenna cable, an accessory cable can be attached to a
connector on the rear of the radio. The accessory cable enables you to connect accessories to the
radio, such as an external speaker, emergency switch, foot-operated PTT, and ignition sensing, etc.

1.2

General
The radio controller consists of three main subsections:
•

digital control

•

audio processing

•

voltage regulation

The digital control section of the radio is based upon an open architecture controller configuration. It
consists of a microprocessor, support memory, support logic, signal MUX ICs, the On/Off circuit, and
general purpose Input/Output circuitry.
The controller uses the Motorola 68HC11FL0 microprocessor (U0101). The controller also has three
external memory devices. These devices consist of a 32KByte SRAM (U0122), a 512KByte FLASH
EEPROM (U0121), and a 16KByte EEPROM (U0111).
NOTE From this point on, the 68HC11FL0 microprocessor is referred to as “µP”. References to a

control head indicate the control heads with display.

Radio Power Distribution
The DC power distribution throughout the radio board is shown in Figure 3-2. Voltage regulation for
the controller is provided by 4 separate devices; U0651 (MC78M05) 5V, U0641 (LM2941) 9.3V,
U0611 (LM2941) SWB+ limited to 16.5V and VSTBY 5V (a combination of R0621 and VR0621). An
additional 5V regulator is located on the RF section.
The DC voltage applied to connector J0601 supplies power directly to the electronic on/off control,
RF power amplifier, 16.5V limiter, 9.3V regulator, Audio PA and 5.6V stabilization circuit. The 9.3V
regulator (U0641) supplies power to the 5V regulator (U0651) and the 6V voltage divider Q0681.
Regulator U0641 is used to generate the 9.3 volts required by some audio circuits, the RF circuitry
and power control circuitry. Input and output capacitors (C0641 and C0644 / C0645) are used to
reduce high frequency noise. R0642 / R0643 set the output voltage of the regulator. If the voltage at
pin 1 is greater than 1.3 volts the regulator output decreases and if the voltage is less than 1.3 volts
the regulator output increases. This regulator output is electronically enabled by a 0 volt signal on
pin 2. Q0661, Q0641 and R0641 are used to disable the regulator when the radio is turned off.
Voltage regulation providing 5V for the digital circuitry is done by U0651. Operating voltage is from
the regulated 9.3V supply. Input and output capacitors (C0651 / C0652 and C0654 / C0655) are
used to reduce high frequency noise and provide proper operation during battery transients. Voltage
sense device U0652 or alternatively U0653 provides a reset output that goes to 0 volts if the
regulator output goes below 4.5 volts. This is used to reset the controller to prevent improper
operation. Diode D0651 prevents discharge of C0652 by negative spikes on the 9.3V voltage.

6881091C63-A

Controller Circuits

Chapter 3: 1-3

Transistor Q0681 and resistors R0681 / R0682 divide the regulated 9.3V down to about 6 volts. This
voltage supplies the 5V regulator, located on the RF section. By reducing the supply voltage of the
regulator, the power dissipation is divided between the RF section and the controller section.
The voltage VSTBY, which is derived directly from the supply voltage by components R0621 and
VR0621, is used to buffer the internal RAM. C0622 allows the battery voltage to be disconnected for
a couple of seconds without losing RAM parameters. Dual diode D0621 prevents radio circuitry from
discharging this capacitor. When the supply voltage is applied to the radio, C0622 is charged via
R0621 and D0621. To avoid the µP entering the wrong mode when the radio is switched on while
the voltage across C0622 is still too low, the regulated 5V supply charges C0622 via diode D0621.

The voltage INT SW B+ from switching transistor Q0661 provides power to the circuit controlling the
audio PA output. The voltage INT SW B+ voltage is monitored by the µP through voltage divider
R0671 / R0672 and line BATTERY VOLTAGE. Diode VR0671 limits the divided voltage to 5.6V to
protect the µP.
Regulator U0611 is used to generate the voltage for the switched supply voltage output (SWB+) at
the accessory connector J0501 pin 13. U0611 is configured to operate as a switch with voltage and
current limit. R0611 / R0612 set the maximum output voltage to 16.5 volts. This limitation is only
active at high supply voltage levels. The regulator output is electronically enabled by a 0 volt signal
on pin 2. Q0661, Q0641 and R0641 are used to disable the regulator when the radio is turned off.
Input and output capacitors (C0603 and C0611 / C0612) are used to reduce high frequency noise.
Diode VR0601 acts as protection against transients and wrong polarity of the supply voltage.
Fuse F0401 prevents damage of the board in case the FLT A+ line is shorted at the control head
connector.

Controller Circuits

Electronic ON/OFF
The radio has circuitry which allows radio software and/or external triggers to turn the radio on or off
without direct user action (for example, automatic turn on when ignition is sensed and off when
ignition is off).
Q0661 is used to provide INT SW B+ to the various radio circuits and to enable the voltage
regulators via transistor Q0641. Q0661 contains an pnp and an npn transistor and acts as an
electronic on/off switch. The switch is on when the collector of the npn transistor within Q0661 is low.
When the radio is off the collector is at supply voltage level. This effectively prevents current flow
from emitter to collector of the pnp transistor. When the radio is turned on the voltage at the base of
the npn transistor is pulled high and the pnp transistor switches on (saturation). With voltage INT
SWB+ now at supply voltage level, transistor Q0641 pulls pin 2 of the voltage regulators U0611 and
U0641 to ground level and thereby enables their outputs.
The electronic on/off circuitry can be enabled by the µP (through ASFIC CMP port GCB2, line DC
POWER ON), the emergency switch (line EMERGENCY CONTROL), the mechanical On/Off/
Volume knob on the control head (line ON OFF CONTROL), or the ignition sense circuitry (line
IGNITION CONTROL). If any of the 4 paths cause a low at the collector of the npn transistor within
Q0661, the electronic “ON” is engaged.

1.5

Emergency
The emergency switch (J0501 pin 9), when engaged, grounds the base of Q0662 via line
EMERGENCY CONTROL. This switches Q0662 off and resistor R0662 pulls the collector of Q0662
and the base of Q0663 to levels above 2 volts. Transistor Q0663 switches on and pulls the collector
of the npn transistor within Q0661 to ground level and thereby enables the voltage regulators via
Q0641. When the emergency switch is released R0541 pulls the base of Q0662 up to 0.6 volts. This
causes the collector of transistor Q0662 to go low (0.2V), thereby switching Q0663 off.
While the radio is switched on, the µP monitors the voltage at the emergency input on the accessory
connector via pin 60 and line GP5 IN ACC9. Three different conditions are distinguished: no
emergency, emergency, and open connection to the emergency switch. If no emergency switch is
connected or the connection to the emergency switch is broken, the resistive divider R0541 / R0512
will set the voltage to about 4.7 volts. If an emergency switch is connected, a resistor to ground
within the emergency switch will reduce the voltage on line GP5 IN ACC9 to inform the µP that the
emergency switch is operational. An engaged emergency switch pulls line GP5 IN ACC9 to ground
level. Diode D0179 limits the voltage to protect the µP input.
While EMERGENCY CONTROL is low, INT SW B+ is on, the µP starts execution, reads that the
emergency input is active through the voltage level of line GP5 IN ACC9, and sets the DC POWER
ON output of the ASFIC CMP pin 13 to a logic high. This high will keep Q0661 and Q0641 switched
on. This operation allows a momentary press of the emergency switch to power up the radio. When
the µP has finished processing the emergency press, it sets the DC POWER ON line to a logic “0”.
This turns off Q0661 and the radio turns off. Notice that the µP is alerted to the emergency condition
via line GP5 IN ACC9. If the radio was already on when emergency was triggered then DC POWER
ON would already be high.

Chapter 3: 1-5

Mechanical ON/OFF
This refers to the typical On/Off/Volume knob, located on the control head, and which turns the radio
on and off.
If the radio is turned off and the On/Off/Volume knob is pressed, line ON OFF CONTROL (J0401 pin
11) goes high and switches the radio’s voltage regulators on as long as the button is pressed. The
µP is alerted through line ON OFF SENSE (U0101 pin 6) which is pulled to low by Q0110 while the
On/Off/Volume knob is pressed. In addition, an interrupt is generated at µP pin 96. The µP asserts
line DC POWER ON via ASFIC CMP, pin 13 high which keeps Q0661 and Q0641, and in turn the
radio, switched on. When the On/Off/Volume knob is released again the control head informs the µP
via SBEP bus about the knob release. (See SBEP Serial Interface subsection for more details.) This
informs the µP to keep the radio switched on and continue with normal operation.
If the On/Off/Volume knob is pressed while the radio is on, the control head informs the µP via SBEP
bus about the knob status. (See SBEP Serial Interface subsection for more details.) After a short
delay time the µP switches the radio off by setting DC POWER ON to low via ASFIC CMP pin 13.

1.7

Ignition
Ignition sense is used to prevent the radio from draining the vehicle’s battery because the engine is
not running.
When the IGNITION input (J0501 pin 10) goes above 5 volts Q0661 is turned on via line IGNITION
CONTROL. Q0661 turns on INT SW B+ and the voltage regulators by turning on Q0641 and the µP
starts execution. The µP is alerted through line GP6 IN ACC10. The voltage at the IGNITION input
turns Q0181 on, which pulls µP pin 74 to low. If the software detects a low state it asserts DC
POWER ON via ASFIC pin 13 high which keeps Q0661 and Q0641 on, and in turn the radio
switched on.
When the IGNITION input goes below 3 volts, Q0181 switches off and R0181 pulls µP pin 74 to
high. This alerts the software to switch off the radio by setting DC POWER ON to low. The next time
the IGNITION input goes above 5 volts the above process will be repeated.

1.8

Microprocessor Clock Synthesizer
The clock source for the µP system is generated by the ASFIC CMP (U0221). Upon power-up the
synthesizer IC (FRAC-N) generates a 16.8 MHz waveform that is routed from the RF section to the
ASFIC CMP pin 34. For the main board controller the ASFIC CMP uses 16.8 MHz as a reference
input clock signal for its internal synthesizer. The ASFIC CMP, in addition to audio circuitry, has a
programmable synthesizer which can generate a synthesized signal ranging from 1200Hz to
32.769MHz in 1200Hz steps.
When power is first applied, the ASFIC CMP will generate its default 3.6864MHz CMOS square
wave UP CLK (on U0221 pin 28) and this is routed to the µP (U0101 pin 90). After the µP starts
operation, it reprograms the ASFIC CMP clock synthesizer to a higher UP CLK frequency (usually
7.3728 or 14.7456 MHz) and continues operation.
The ASFIC CMP may be reprogrammed to change the clock synthesizer frequencies at various
times depending on the software features that are executing. In addition, the clock frequency of the
synthesizer is changed in small amounts if there is a possibility of harmonics of the clock source
interfering with the desired radio receive frequency.

6881091C63-A

Chapter 3: 1-6

Controller Circuits

The ASFIC CMP synthesizer loop uses C0245, C0246 and R0241 to set the switching time and jitter
of the clock output. If the synthesizer cannot generate the required clock frequency it will switch
back to its default 3.6864MHz output.
Because the ASFIC CMP synthesizer and the µP system will not operate without the 16.8 MHz
reference clock it (and the voltage regulators) should be checked first when debugging the system.
The µP uses XTAL Y0131 and associated components to form a Real Time Clock (RTC). It may be
used to display the time on control heads with display or as time stamp for incoming calls or
messages. The real time clock is powered from the voltage VSTBY to keep it running while the radio
is switched off. When the radio is disconnected from its supply voltage, the time must be set again.

1.9

Serial Peripheral Interface (SPI)
The µP communicates to many of the ICs through its SPI port. This port consists of SPI TRANSMIT
DATA (MOSI) (U0101-100), SPI RECEIVE DATA (MISO) (U0101-99), SPI CLK (U0101-1) and chip
select lines going to the various ICs, connected on the SPI PORT (BUS). This BUS is a
synchronous bus, in that the timing clock signal CLK is sent while SPI data (SPI TRANSMIT DATA
or SPI RECEIVE DATA) is sent. Therefore, whenever there is activity on either SPI TRANSMIT
DATA or SPI RECEIVE DATA there should be a uniform signal on CLK. The SPI TRANSMIT DATA
is used to send serial from a µP to a device, and SPI RECEIVE DATA is used to send data from a
device to a µP.
On the controller there are two ICs on the SPI BUS, ASFIC CMP (U0221-22), and EEPROM
(U0111-5). In the RF sections there are 2 ICs on the SPI BUS, the FRAC-N Synthesizer, and the
Power Control IC (PCIC). The SPI TRANSMIT DATA and CLK lines going to the RF section are
filtered by L0481 / R0481 and L0482 / R0482 to minimize noise. The chip select line CSX from
U0101 pin 2 is shared by the ASFIC CMP, FRAC-N Synthesizer and PCIC. Each of these ICs check
the SPI data and when the sent address information matches the IC’s address, the following data is
processed. The chip select lines for the EEPROM (EE CS), Voice Storage (VS CS), expansion
board (EXP1 CS, EXP2 CS) and option board (OPT CS) are decoded by the address decoder
U0141.
When the µP needs to program any of these ICs it brings the chip select line CSX to a logic “0” and
then sends the proper data and clock signals. The amount of data sent to the various ICs are
different; e.g., the ASFIC CMP can receive up to 19 bytes (152 bits) while the PCIC can receive up
to 6 bytes (48 bits). After the data has been sent the chip select line is returned to logic “1”.
The option board interfaces are different in that the µP can also read data back from devices
connected.The timing and operation of this interface is specific to the option connected, but
generally follows the pattern:
1.

an option board device generates a service request via J0551-29, line RDY and µP pin 79,

2.

the main board asserts a chip select for that option board device via U0141-14, line OPT CS,
J0551-30,

3.

the main board µP generates the CLK (J0551-3),

4.

the main board µP writes serial data via J0551-15 and reads serial data via J0551-16 and,

5.

when data transfer is complete the main board terminates the chip select and CLK activity.

Chapter 3: 1-7

SBEP Serial Interface
The SBEP serial interface allows the radio to communicate with the Customer Programming
Software (CPS), or the Universal Tuner via the Radio Interface Box (RIB) or the cable with internal
RIB. This interface connects to the microphone connector via control head connector (J0401-8) and
to the accessory connector J0501-17 and comprises BUS+. The line is bi-directional, meaning that
either the radio or the RIB can drive the line. The µP sends serial data via pin 98 and D0101 and it
reads serial data via pin 97. Whenever the µP detects activity on the BUS+ line, it starts
communication.
In addition, the SBEP serial interface is used to communicate with a connected control head. When
a control head key is pressed or the volume knob is rotated, the line ON OFF CONTROL goes high.
This turns on transistor Q0110 which pulls line ON OFF SENSE and µP pin 6 to ground level. In
addition, an interrupt is generated at µP pin 96. This indicates that the control head wants to start
SBEP communication. The µP then requests the data from the control head. The control head starts
sending and after all data has been sent, the ON OFF CONTROL line goes low. The control head
ignores any data on BUS+ during SBEP communication with the CPS or Universal Tuner.

1.11

General Purpose Input/Output
The controller provides eight general purpose lines (DIG1 through DIG8) available on the accessory
connector J0501 to interface to external options. Lines DIG IN 1, 3, 5, 6 are inputs, DIG OUT 2 is an
output and DIG IN OUT 4, 7, 8 are bi-directional. The software and the hardware configuration of the
radio model define the function of each port.
•

DIG IN 1 can be used as external PTT input, DATA PTT input or others, set by the CPS.
The µP reads this port via pin 77 and Q0171.

•

DIG OUT 2 can be used as normal output or external alarm output, set by the CPS. Transistor
Q0173 is controlled by the µP via ASFIC CMP pin 14.

•

DIG IN 3 is read by µP pin 61 via resistor R0176

•

DIG IN 5 can be used as normal input or emergency input, set by the CPS. The µP reads this
port via R0179 and µP pin 60. Diode D0179 limits the voltage to protect the µP input.

•

DIG IN 6 can be used as normal input, set by the CPS. The µP reads this port via pin 74 and
Q0181.

•

DIG IN OUT 4,7,8 are bi-directional and use the same circuit configuration. Each port uses an
output transistor Q0177, Q0183, Q0185 controlled by µP pins 46, 47, 53. The ports are read
by µP pins 75, 54, 76. To use one of the ports as input the µP must turn off the corresponding
output transistor.

In addition the signals from DIG IN 1, DIG IN OUT 4 are fed to the option board connector J0551
and the expansion board connector J0451.

Controller Circuits

Normal Microprocessor Operation
For this radio, the µP is configured to operate in one of two modes, expanded and bootstrap. In
expanded mode the µP uses external memory devices to operate, whereas in bootstrap operation
the µP uses only its internal memory. In normal operation of the radio the µP is operating in
expanded mode as described below.
In expanded mode on this radio, the µP (U0101) has access to 3 external memory devices; U0121
(FLASH EEPROM), U0122 (SRAM), U0111 (EEPROM). Also, within the µP there are 3 KBytes of
internal RAM, as well as logic to select external memory devices.
The external EEPROM (U0111) space contains the information in the radio which is customer
specific, referred to as the codeplug. This information consists of items such as: 1) what band the
radio operates in, 2) what frequencies are assigned to what channel, and 3) tuning information. (See
the particular device subsection for more details.)
The external SRAM (U0122) as well as the µP’s own internal RAM space are used for temporary
calculations required by the software during execution. All of the data stored in both of these
locations is lost when the radio powers off. (See the particular device subsection for more details.)
The FLASH EEPROM contains the actual Radio Operating Software. This software is common to all
open architecture radios within a given model type. For example, trunking radios may have a
different version of software in the FLASH EEPROM than non-trunking radios. (See the particular
device subsection for more details.)
The µP provides an address bus of 16 address lines (ADDR 0 - ADDR 15), and a data bus of 8 data
lines (DATA 0 - DATA 7). There are also 3 control lines; CSPROG (U0101-38) to chip select U012130 (FLASH EEPROM), CSGP2 (U0101-41) to chip select U0122-20 (SRAM) and PG7 R W (U01014) to select whether to read or to write. The external EEPROM (U0111-1), the OPTION BOARD and
EXPANSION BOARD are selected by 3 lines of the µP using address decoder U0141. The chips
ASFIC CMP / FRAC-N / PCIC are selected by line CSX (U0101-2).
When the µP is functioning normally, the address and data lines should be toggling at CMOS logic
levels. Specifically, the logic high levels should be between 4.8 and 5.0V, and the logic low levels
should be between 0 and 0.2V. No other intermediate levels should be observed, and the rise and
fall times should be <30ns.
The low-order address lines (ADDR 0 - ADDR 7) and the data lines (DATA 0-DATA 7) should be
toggling at a high rate, e.g., you should set your oscilloscope sweep to 1us/div. or faster to observe
individual pulses. High speed CMOS transitions should also be observed on the µP control lines.
On the µP the lines XIRQ (U0101-48), MODA LIR (U0101-58), MODB VSTPY (U0101-57) and
RESET (U0101-94) should be high at all times during normal operation. Whenever a data or
address line becomes open or shorted to an adjacent line, a common symptom is that the RESET
line goes low periodically, with the period being in the order of 20ms. In the case of shorted lines you
may also detect the line periodically at an intermediate level, i.e. around 2.5V when 2 shorted lines
attempt to drive to opposite rails.
The MODA LIR (U0101-58) and MODB VSTPY (U0101-57) inputs to the µP must be at a logic “1”
for it to start executing correctly. After the µP starts execution it will periodically pulse these lines to
determine the desired operating mode. While the Central Processing Unit (CPU) is running, MODA
LIR is an open-drain CMOS output which goes low whenever the µP begins a new instruction (an
instruction typically requires 2-4 external bus cycles, or memory fetches). However, since it is an
open-drain output, the waveform rise assumes an exponential shape similar to an RC circuit.

6881091C63-A

Controller Circuits

Chapter 3: 1-9

There are 8 analog-to-digital converter ports (A/D) on U0101. They are labeled within the device
block as PE0-PE7. These lines sense the voltage level ranging from 0 to 5V of the input line and
convert that level to a number ranging from 0 to 255 which can be read by the software to take
appropriate action.
For example U0101-67 is the battery voltage detect line. R0671 and R0672 form a resistor divider
on INT SWB+. With 30K and 10K and a voltage range of 11V to 17V, that A/D port would see 2.74V
to 4.24V which would then be converted to ~140 to 217 respectively.
U0101-69 is the high reference voltage for the A/D ports on the µP. Capacitor C0101 filters the 5V
reference. If this voltage is lower than 5V the A/D readings will be incorrect. Likewise U0101-68 is
the low reference for the A/D ports. This line is normally tied to ground. If this line is not connected to
ground, the A/D readings will be incorrect.

1.13

FLASH Electronically Erasable Programmable Memory (FLASH EEPROM)
The 512K Byte FLASH EEPROM (U0121) contains the radio’s operating software. This software is
common to all open architecture radios within a given model type. For example, trunking radios may
have a different version of software in the FLASH EEPROM than non-trunking radios. This is, as
opposed to the codeplug information stored in EEPROM (U0111) which could be different from one
user to another in the same company.
In normal operating mode, this memory is read-only; it cannot be written to. The memory access
signals (CE, OE and WE) are generated by the µP.
To upgrade/reprogram the FLASH software, the µP must be set in bootstrap operating mode. This is
done by pulling µP pins MODA LIR (U0101-58) and MODB VSTBY (U0101-57) to low during power
up. When accessory connector pin 18 is at ground level, diode D0151 will pull both µP pins to low.
The same can be done by a level of 12 volts on line ON OFF CONTROL from the control head.
Q0151 pulls diode D0151 and in turn both µP pins to low. Diode VR0151 prevents entering
bootstrap operating mode during normal power up.
In bootstrap operating mode the µP controls the FLASH EN OE (U0121-32) input by µP pin 86. Chip
select (U0121-30) and read or write operation (U0121-7) are controlled by µP pins 38 and 4.
The FLASH device may be reprogrammed 1,000 times without issue. It is not recommended to
reprogram the FLASH device at a temperature below 0°C.
Capacitor C0121 serves to filter out any AC noise which may ride on 5V at U0121.

1.14

Electrically Erasable Programmable Memory (EEPROM)
The external 16 KByte EEPROM (U0111) contains additional radio operating parameters such as
operating frequency and signaling features, commonly know as the codeplug. It is also used to store
radio operating state parameters such as current mode and volume. This memory can be written to
in excess of 100,000 times and will retain the data when power is removed from the radio. The
memory access signals (SI, SO and SCK) are generated by the µP and chip select (CS) is
generated by address decoder U0141-15.

Controller Board Audio and Signaling Circuits

Static Random Access Memory (SRAM)
The SRAM (U0121) contains temporary radio calculations or parameters that can change very
frequently, and which are generated and stored by the software during its normal operation. The
information is lost when the radio is turned off.
The device allows an unlimited number of write cycles. SRAM accesses are indicated by the CS
signal U0122-20 (which comes from U0101-CSGP2) going low. U0122 is commonly referred to as
the external RAM as opposed to the internal RAM which is the 3 KBytes of RAM which is part of the
68HC11FL0. Both RAM spaces serve the purpose. However, the internal RAM is used for the
calculated values which are accessed most often.
Capacitor C0122 serves to filter out any AC noise which may ride on 5V at U0122.

2.1

Audio Signaling Filter IC with Compander (ASFIC CMP)
The ASFIC CMP (U0221) used in the controller has 4 functions:
1.

RX/TX audio shaping, i.e. filtering, amplification, attenuation

2.

RX/TX signaling, PL/DPL/HST/MDC

3.

Squelch detection

4.

µP clock signal generation (see Section 1.8: Microprocessor Clock Synthesizer)

The ASFIC CMP is programmable through the SPI BUS (U0221-20/21/22), normally receiving 19
bytes. This programming sets up various paths within the ASFIC CMP to route audio and/or
signaling signals through the appropriate filtering, gain and attenuator blocks. The ASFIC CMP also
has 6 General Control Bits GCB0-5 which are CMOS level outputs and used for NOISE BLANKER
(GCB0) in Low Band radios, EXTERNAL ALARM (GCB1) and DC POWER ON (GCB2) to switch
the voltage regulators (and the radio) on and off. GCB3 controls U0251 pin 11 to output either RX
FLAT AUDIO or RX FILTERED AUDIO on the accessory connector pin 11. GCB4 controls U0251
pin 10 to use either the external microphone input or the voice storage playback signal. GCB5 is
used to switch the audio PA on and off.

Figure 3-3 Transmit Audio Paths

2.2.1

Mic/Data Input Path
The radio supports 2 distinct microphone paths known as internal (from control head) and external
mic (from accessory connector J0501-2) and an auxiliary path (FLAT TX AUDIO, from accessory
connector J0501-5). The microphones used for the radio require a DC biasing voltage provided by a
resistive network.
These two microphone audio input paths enter the ASFIC CMP at U0221-48 (external mic) and
U0221-46 (internal mic). Following the internal mic path; the microphone is plugged into the radio
control head and is connected to the controller board via J0401-9.
From here the signal is routed via R0409 and line INT MIC to R0205. R0201 and R0202 provide the
9.3VDC bias. Resistive divider R0205 / R0207 divide the input signal by 5.5 and provide input
protection for the CMOS amplifier input. R0202 and C0201 provide a 560 ohm AC path to ground
that sets the input impedance for the microphone and determines the gain based on the emitter
resistor in the microphone’s amplifier circuit.
C0204 serves as a DC blocking capacitor. The audio signal at U0221-46 (TP0221) should be
approximately 14mV for 1.5kHz or 3kHz of deviation with 12.5kHz or 25kHz channel spacing.
The external microphone signal enters the radio on accessory connector J0501 pin 2 and is routed
via line EXT MIC to R0206. R0203 and R0204 provide the 9.3VDC bias. Resistive divider R0206 /
R0208 divide the input signal by 5.5 and provide input protection for the CMOS amplifier input.

6881091C63-A

Chapter 3: 1-12

Controller Board Audio and Signaling Circuits

R0204 and C0202 provide a 560 ohm AC path to ground that sets the input impedance for the
microphone and determines the gain based on the emitter resistor in the microphone’s amplifier
circuit.
C0254 serves as a DC blocking capacitor. Multi switch U0251 controlled by ASFIC CMP port GCB4
selects either the external microphone input signal or the voice storage playback signal for entering
the ASFIC CMP at pin 48. The audio signal at U0221-48 (TP0222) should be approximately 14mV
for 1.5kHz or 3kHz of deviation with 12.5kHz or 25kHz channel spacing.
The FLAT TX AUDIO path is used for transmitting data signals and has therefore no limiter or filters
enabled inside the ASFIC CMP. When this path is enabled via CPS and DATA PTT is asserted, any
signal on this path is directly fed to the modulator. Signals applied to this path either via accessory
connector J0501, expansion board connector J0451 or option board connector J0551 must be
filtered and set to the correct level externally or on the option board in order not to exceed the
maximum specified transmit deviation and transmitted power in the adjacent channels. The
attenuator inside the ASFIC CMP changes the FM deviation of the data signal according to the
channel spacing of the active transmit channel.
The FLAT TX AUDIO signal from accessory connector J0501-5 is fed to the ASFIC CMP (U0221)
pin 42 through C0541 and line FLAT TX RTN, switch U0251 and buffer U0211-4. When the radio
switches from receive to transmit mode the µP opens switch U0251 for a short period to prevent that
any applied signal can cause a transmit frequency offset. Buffer U0211-4 sets the correct DC level
and ensures a short settle period when the radio is switched on. Inside the ASFIC CMP the signal is
routed directly to the attenuator, which sets the FM deviation according to the channel spacing of the
active transmit channel and emerges from the ASFIC CMP at U0221-40, at which point it is routed
to the RF section.
The ASFIC has an internal AGC that can control the gain in the mic audio path. The AGC can be
disabled / enabled by the µP. Another feature that can be enabled or disabled in the ASFIC is the
VOX. This circuit, along with the capacitor at U0221-7, provides a DC voltage that can allow the µP
to detect microphone audio. The ASFIC can also be programmed to route the microphone audio to
the speaker for public address operation.
2.2.2

PTT Sensing and TX Audio Processing
Microphone PTT coming from the control head is sent via SBEP bus to the µP. An external PTT can
be generated by grounding pin 3 on the accessory connector if this input is programmed for PTT by
the CPS. When microphone PTT is sensed, the µP will always configure the ASFIC CMP for the
“internal” mic audio path, and external PTT will result in the external mic audio path being selected.
Inside the ASFIC CMP, the mic audio is filtered to eliminate frequency components outside the 3003000Hz voice band, and pre-emphasized if pre-emphasis is enabled. The signal is then limited to
prevent the transmitter from over deviating. The limited mic audio is then routed through a summer,
which is used to add in signaling data, and then to a splatter filter to eliminate high frequency
spectral components that could be generated by the limiter. The audio is then routed to an
attenuator, which is tuned in the factory or the field to set the proper amount of FM deviation. The TX
audio emerges from the ASFIC CMP at U0221-40 MOD IN, at which point it is routed to the RF
section.
Dependent on the radio model, input pin 3 on the accessory connector can be programmed for
DATA PTT by the CPS. When DATA PTT is sensed, the µP will always configure the ASFIC CMP for
the flat TX audio path. Limiter and any filtering will be disabled. The signal is routed directly to the
attenuator, which sets the FM deviation according to the channel spacing of the active transmit

channel and emerges from the ASFIC CMP at U0221-40, at which point it is routed to the RF
section.
2.2.3

TX Secure Audio (Optional)
The audio follows the normal transmit audio processing until it emerges from the ASFIC CMP TX
SND pin (U0221-44), which is fed to the Secure board residing at option connector J0551-33. The
Secure board contains circuitry to amplify, encrypt, and filter the audio. The encrypted signal is then
fed back from J0551-32 to the ASFIC CMP TX RTN input (U0221-36). The signal level at this pin
should be about 65mVrms. The signal is then routed through the TX path in the ASFIC CMP and
emerges at MOD IN pin 40.

2.2.4

Option Board Transmit Audio
The audio follows the normal transmit audio processing until it emerges from the ASFIC CMP TX
SND pin (U0221-44), which is fed to the option board residing at option connector J0551-33. The
option board contains circuitry to process the audio. The processed signal is then fed back from
J0551-32 to the ASFIC CMP TX RTN input (U0221-36). The signal level at this pin should be about
65mVrms. The signal is then routed through the TX path in the ASFIC CMP and emerges at MOD IN
pin 40.

Figure 3-4 Transmit Signaling Paths
From a hardware point of view, there are 3 types of signaling:
•

Sub-audible data (PL / DPL / Connect Tone) that gets summed with transmit voice or
signaling,

•

DTMF data for telephone communication in trunked and conventional systems, and

•

Audible signaling including MDC and high-speed trunking.

NOTE All three types are supported by the hardware while the radio software determines which

signaling type is available.

6881091C63-A

Chapter 3: 1-14

2.3.1

Controller Board Audio and Signaling Circuits

Sub-audible Data (PL/DPL)
Sub-audible data implies signaling whose bandwidth is below 300Hz. PL and DPL waveforms are
used for conventional operation and connect tones for trunked voice channel operation. The
trunking connect tone is simply a PL tone at a higher deviation level than PL in a conventional
system. Although it is referred to as “sub-audible data”, the actual frequency spectrum of these
waveforms may be as high as 250 Hz, which is audible to the human ear. However, the radio
receiver filters out any audio below 300Hz, so these tones are never heard in the actual system.
Only one type of sub-audible data can be generated by U0221 (ASFIC CMP) at any one time. The
process is as follows, using the SPI BUS, the µP programs the ASFIC CMP to set up the proper lowspeed data deviation and select the PL or DPL filters. The µP then generates a square wave which
strobes the ASFIC PL / DPL encode input LSIO U0221-18 at twelve times the desired data rate. For
example, for a PL frequency of 103Hz, the frequency of the square wave would be 1236Hz.
This drives a tone generator inside U0221 which generates a staircase approximation to a PL sine
wave or DPL data pattern. This internal waveform is then low-pass filtered and summed with voice
or data. The resulting summed waveform then appears on U0221-40 (MOD IN), where it is sent to
the RF board as previously described for transmit audio. A trunking connect tone would be
generated in the same manner as a PL tone.

2.3.2

High Speed Data
High speed data refers to the 3600 baud data waveforms, known as Inbound Signaling Words
(ISWs) used in a trunking system for high speed communication between the central controller and
the radio. To generate an ISW, the µP first programs the ASFIC CMP (U0221) to the proper filter and
gain settings. It then begins strobing U0221-19 (HSIO) with a pulse when the data is supposed to
change states. U0221’s 5-3-2 State Encoder (which is in a 2-state mode) is then fed to the postlimiter summer block and then the splatter filter. From that point it is routed through the modulation
attenuators and then out of the ASFIC CMP to the RF board. MDC is generated in much the same
way as trunking ISW. However, in some cases these signals may also pass through a data preemphasis block in the ASFIC CMP. Also these signaling schemes are based on sending a
combination of 1200 Hz and 1800 Hz tones only. Microphone audio is muted during high speed data
signaling.

2.3.3

Dual Tone Multiple Frequency (DTMF) Data
DTMF data is a dual tone waveform used during phone interconnect operation. It is the same type of
tones which are heard when using a “Touch Tone” telephone.
There are seven frequencies, with four in the low group (697, 770, 852, 941Hz) and three in the high
group (1209, 1336, 1477Hz).
The high-group tone is generated by the µP (U0101-44) strobing U0221-19 at six times the tone
frequency for tones less than 1440Hz or twice the frequency for tones greater than 1440Hz. The low
group tone is generated by the ASFIC CMP, controlled by the µP via SPI bus. Inside U0221 the lowgroup and high-group tones are summed (with the amplitude of the high group tone being
approximately 2 dB greater than that of the low group tone) and then pre-emphasized before being
routed to the summer and splatter filter. The DTMF waveform then follows the same path as was
described for high-speed data.

2.4.1

Squelch Detect
The radio’s RF circuits are constantly producing an output at the discriminator (IF IC). This signal
(DISC AUDIO) is routed to the ASFIC CMP’s squelch detect circuitry input DISC (U0221-2). All of
the squelch detect circuitry is contained within the ASFIC CMP. Therefore from a user’s point of
view, DISC AUDIO enters the ASFIC CMP, and the ASFIC CMP produces two CMOS logic outputs
based on the result. They are CH ACT (U0221-16) and SQ DET (U0221-17).
The squelch signal entering the ASFIC CMP is amplified, filtered, attenuated, and rectified. It is then
sent to a comparator to produce an active high signal on CH ACT. A squelch tail circuit is used to
produce SQ DET (U0221-17) from CH ACT. The state of CH ACT and SQ DET is high (logic “1”)
when carrier is detected, otherwise low (logic “0”).
CH ACT is routed to the µP pin 84 while SQ DET is routed to the µP pin 83.

6881091C63-A

Chapter 3: 1-16

Controller Board Audio and Signaling Circuits

SQ DET is used to determine all audio mute / unmute decisions except for Conventional Scan. In
this case CH ACT is a pre-indicator as it occurs slightly faster than SQ DET.
2.4.2

Audio Processing and Digital Volume Control
The receiver audio signal enters the controller section from the IF IC on DISC AUDIO. The signal is
DC coupled by R0228 and enters the ASFIC CMP via the DISC pin U0221-2.
Inside the ASFIC CMP, the signal goes through 2 paths in parallel, the audio path and the PL/DPL
path.
The audio path has a programmable amplifier, whose setting is based on the channel bandwidth
being received, then a LPF filter to remove any frequency components above 3000Hz and then an
HPF to strip off any sub-audible data below 300Hz. Next, the recovered audio passes through a deemphasis filter if it is enabled (to compensate for Pre-emphasis which is used to reduce the effects
of FM noise). The IC then passes the audio through the 8-bit programmable attenuator whose level
is set depending on the value of the volume control. Finally the filtered audio signal passes through
an output buffer within the ASFIC CMP. The audio signal exits the ASFIC CMP at pin AUDIO
(U0221-41).
The µP programs the attenuator, using the SPI BUS, based on the volume setting. The minimum /
maximum settings of the attenuator are set by codeplug parameters.
Since sub-audible signaling is summed with voice information on transmit, it must be separated from
the voice information before processing. Any sub-audible signaling enters the ASFIC CMP from the
IF IC at DISC U0221-2. Once inside it goes through the PL/DPL path. The signal first passes
through one of 2 low-pass filters, either PL low-pass filter or DPL/LST low-pass filter. Either signal is
then filtered and goes through a limiter and exits the ASFIC CMP at LSIO (U0221-18). At this point
the signal will appear as a square wave version of the sub-audible signal which the radio received.
The µP U0101-80 will decode the signal directly to determine if it is the tone / code which is currently
active on that mode.

2.4.3

Audio Amplification Speaker (+) Speaker (–)
The output of the ASFIC CMP’s digital volume pot, U0221-41 is routed through DC blocking
capacitor C0265 to a buffer formed by U0211-1. Resistors R0265 and R0268 set the correct input
level to the audio PA (U0271). This is necessary because the gain of the audio PA is 46 dB, and the
ASFIC CMP output is capable of overdriving the PA unless the maximum volume is limited. Resistor
R0267 and capacitor C0267 increase frequency components below 350Hz.
The audio then passes through R0269 and C0272 which provides AC coupling and low frequency
roll-off. C0273 provides high frequency roll-off as the audio signal is routed to pins 1 and 9 of the
audio power amplifier U0271.
The audio power amplifier has one inverted and one non-inverted output that produces the
differential audio output SPK+ / SPK- (U0271-4/6). The inputs for each of these amplifiers are pins 1
and 9 respectively; these inputs are both tied to the received audio. The audio PA’s DC biases are
not activated until the audio PA is enabled at pin 8.
The audio PA is enabled via the ASFIC CMP (U0221-38). When the base of Q0271 is low, the
transistor is off and U0271-8 is high, using pull up resistor R0273, and the audio PA is ON. The
voltage at U0273-8 must be above 8.5VDC to properly enable the device.

6881091C63-A

Controller Board Audio and Signaling Circuits

Chapter 3: 1-17

If the voltage is between 3.3 and 6.4V, the device will be active but has its input (U0273-1/9) off. This
is a mute condition which is used to prevent an audio pop when the PA is enabled.
The SPK+ and SPK- outputs of the audio PA have a DC bias which varies proportionately with FLT
A+ (U0271-7). FLT A+ of 11V yields a DC offset of 5V, and FLT A+ of 17V yields a DC offset of 8.5V.
If either of these lines is shorted to ground, it is possible that the audio PA will be damaged. SPK+
and SPK- are routed to the accessory connector (J0501-16 and 1) and to the control head
(connector J0401-2 and 3).
2.4.4

Handset Audio
Certain handheld accessories have a speaker within them which require a different voltage level
than that provided by U0271. For those devices HANDSET AUDIO is available at control head
connector J0401-7.
The received audio from the output of the ASFIC CMP’s digital volume attenuator and buffered by
U0211-1 is also routed to U0211-3 pin 9 where it is amplified 20 dB; this is set by the 10k/100k
combination of R0261 and R0262. This signal is routed from the output of the op-amp U0211-3 pin 8
to J0401-7. The control head sends this signal directly out to the microphone jack. The maximum
value of this output is 6.6Vp-p.

2.4.5

Filtered Audio and Flat Audio
The ASFIC CMP has an audio whose output at U0221-39 has been filtered and de-emphasized, but
has not gone through the digital volume attenuator. From ASFIC CMP U0221-39 the signal is routed
via R0251 through gate U0251-12 and AC coupled to U0211-2. The gate controlled by ASFIC CMP
port GCB3 (U0221-35) selects between the filtered audio signal from the ASFIC CMP pin 39
(URXOUT) or the unfiltered (flat) audio signal from the ASFIC CMP pin 10 (UIO). R0251 and R0253
determine the gain of op-amp U0211-2 for the filtered audio while R0252 and R0253 determine the
gain for the flat Audio. The output of U0253-7 is then routed to J0501-11 via DC blocking capacitor
C0542 and R0531. Note that any volume adjustment of the signal on this path must be done by the
accessory.

2.4.6

RX Secure Audio (Optional)
Discriminator audio, which is now encrypted audio, follows the normal receive audio processing until
it emerges from the ASFIC CMP UIO pin (U0221-10), which is fed to the Secure board residing at
option connector J0551-35. On the Secure board, the encrypted signal is converted back to normal
audio format, and then fed back through (J0551-34) to AUX RX of the ASFIC CMP (U0221-43).
From then on it follows a path identical to conventional receive audio, where it is filtered (0.3 - 3kHz)
and de-emphasized. The signal URX SND from the ASFIC CMP (U0221-39), also routed to option
connector J0551-28, is not used for the Secure board but for other option boards.

2.4.7

Option Board Receive Audio
Unfiltered audio from the ASFIC CMP pin UIO (U0221-10) enters the option board at connector
J0551-35. Filtered audio from the ASFIC CMP pin URXOUT (U0221-39) enters the option board at
connector J0551-28. On the option board, the signal may be processed, and then fed back through
J0551-34 to AUX RX of the ASFIC CMP (U0221-43). From then on it follows a path identical to
conventional receive audio, where it may be filtered (0.3 - 3kHz) and de-emphasized.

Sub-audible (PL/DPL) and High Speed Data Decoder
The ASFIC CMP (U0221) is used to filter and limit all received data. The data enters the ASFIC
CMP at input DISC (U0221-2). Inside U0221 the data is filtered according to data type (HS or LS),
then it is limited to a 0-5V digital level. The MDC and trunking high speed data appear at U0221-19,
where it connects to the µP U0101-82
The low speed limited data output (PL, DPL, and trunking LS) appears at U0221-18, where it
connects to the µP U0101-80.
The low speed data is read by the µP at twice the frequency of the sampling waveform; a latch
configuration in the ASFIC CMP stores one bit every clock cycle. The external capacitors C0236,
and C0244 set the low frequency pole for a zero crossings detector in the limiters for PL and HS
data. The hysteresis of these limiters is programmed based on the type of received data.

2.5.2

Alert Tone Circuits
When the software determines that it needs to give the operator an audible feedback (for a good key
press, or for a bad key press), or radio status (trunked system busy, phone call, circuit failures), it
sends an alert tone to the speaker. It does so by sending SPI BUS data to U0221 which sets up the
audio path to the speaker for alert tones. The alert tone itself can be generated in one of two ways:
internally by the ASFIC CMP, or externally using the µP and the ASFIC CMP.
The allowable internal alert tones are 304, 608, 911, and 1823Hz. In this case a code contained
within the SPI BUS load to the ASFIC CMP sets up the path and determines the tone frequency, and
at what volume level to generate the tone. (It does not have to be related to the voice volume
setting.)
For external alert tones, the µP can generate any tone within the 100-3000Hz audio band. This is
accomplished by the µP generating a square wave which enters the ASFIC CMP at U0221-19.
Inside the ASFIC CMP this signal is routed to the alert tone generator.

6881091C63-A

Controller Board Audio and Signaling Circuits

Chapter 3: 1-19

The output of the generator is summed into the audio chain just after the RX audio de-emphasis
block. Inside U0221 the tone is amplified and filtered, then passed through the 8-bit digital volume
attenuator, which is typically loaded with a special value for alert tone audio. The tone exits at
U0221-41 and is routed to the audio PA like receive audio

2.6

Voice Storage (Optional)
The Voice Storage (VS) option can be used to store audio signals coming from the receiver or from
the microphone. Any stored audio signal can be played back over the radio’s speaker or sent out via
the radio’s transmitter.
The Voice Storage option can by placed on the controller section or on an additional board which
resides on option board connector J0551. Voice Storage is included on the PassPort board. Voice
Storage IC U0301 provides all required functionality and is powered from 3.3 volts regulator U0351
which, is powered from the regulated 5 volts. Dual shottky diode D0301 reduces the supply voltage
for U0301 to 3 volts. The µP controls U0301 via SPI bus lines CLK (U0301-8), DATA (U0301-10)
and MISO (U0301-11). To transfer data, the µP first selects the U0301 via address decoder U0141,
line VS CS and U0301 pin 9. Then the µP sends data through line DATA and receives data through
line MISO. Pin 2 (RAC) of U0301 indicates the end of a message row by a low state for 12.5 ms and
connects to µP pin 52. A low at pin 5 (INT), which is connected to µP pin 55 indicates that the Voice
Storage IC requires service from the µP.
Audio, either from the radio’s receiver or from one of the microphone inputs, emerges the ASFIC
CMP (U0221) at pin 39, is buffered by op-amp U0341-1 and enters the Voice Storage IC U0301 at
pin 25. During playback, the stored audio emerges U0301 at pin 20. To transmit the audio signal it is
fed through resistive divider R0344 / R0345 and line VS MIC to input selector IC U0251. When this
path is selected by the µP via ASFIC CMP port GCB 4, the audio signal enters the ASFIC CMP at
pin 48 and is processed like normal transmit audio. To play the stored audio over the radio’s
speaker, the audio from U0301 pin 20 is buffered by op-amp U0341-2 and fed via switch U0342 and
line FLAT RX SND to ASFIC CMP pin 10 (UIO). In this case, this ASFIC CMP pin is programmed as
input and feeds the audio signal through the normal receiver audio path to the speaker or handset.
Switch U0342 is controlled by the µP via ASFIC CMP port GCB 4 and feeds the stored audio only to
the ASFIC CMP port UIO when it is programmed as input.

because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.

Introduction
This chapter provides a detailed theory of operation for the VHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

VHF (136-174 MHz) 1-25W Receiver Front-End

2.1

Receiver Front-End
The receiver is able to cover the VHF range from 136 to 174 MHz. It consists of four major blocks:
front-end bandpass filters and pre-amplifier, first mixer, high-IF, low-IF and receiver back-end. Two
varactor-tuned bandpass filters perform antenna signal pre-selection. A passive double-balanced
mixer converts the signal to the first IF of 44.85 MHz. High-side first injection is used.

Chapter 4: 2-2

VHF (136-174 MHz) 1-25W Receiver Front-End

There are two 2-pole 44.85 MHz crystal filters in the high-IF section and 2 pairs of 455 kHz ceramic
filters in the low-IF section to provide the required adjacent channel selectivity. The correct pair of
ceramic filters for 12.5 or 25kHz channel spacing is selected via control line BWSELECT. The
second IF at 455 kHz is mixed, amplified and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuitry, before being applied to the
receiver pre-selector filter (C3001, C3002, D3001 and associated components). The 2-pole preselector filter tuned by the dual varactor diode D3001 pre-selects the incoming signal (RXIN) from
the antenna switch to reduce spurious effects to following stages. The tuning voltage (FECNTL_1)
ranging from 2 volts to 8 volts is controlled by pin 20 of PCIC (U3501) in the Transmitter section. A
dual hot carrier diode (D3003) limits any inband signal to 0 dBm to prevent damage to the preamplifier.
The RF pre-amplifier is an SMD device (Q3001) with collector-base feedback to stabilize gain,
impedance, and intermodulation. Transistor Q3002 compares the voltage drop across resistor
R3002 with a fixed base voltage from divider R3011, R3000 and R3012, and adjusts the base
current of Q3001 as necessary to maintain its collector current constant at approximately 15-20 mA.
Operating voltage is from the regulated 9.3V supply (9V3). During transmit, 9.1 volts (K9V1) turns off
both transistors Q3002 and Q3001. This protects the RF pre-amplifier from excessive dissipation
during transmit mode. A switchable 3dB pad (R3022, R3024, R3016 and R3018) controlled via Line
FECNTL_2 and Q3021 stabilizes the output impedance and intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
The dual varactor diode D3004 is controlled by the same signal FECNTL_1, which controls the preselector filter.

2.3

First Mixer and High Intermediate Frequency (IF)
The signal coming from the front-end is converted to the high-IF frequency of 44.85 MHz using a
passive double-balanced mixer (D3031). Its ports are matched for incoming RF signal conversion to
the 44.85 MHz IF using high side injection. The high-side injection signal (RXINJ) from the
frequency synthesizer circuitry has a level of approximately 13 dBm and is injected via matching
transformer T3002.
The mixer IF output signal (IF) from transformer T3001 pin 2 is fed to the first two pole crystal filter
FL3101. The filter output in turn is matched to the following IF amplifier.
The IF amplifier Q3101 is actively biased by a collector base feedback (R3101, R3106) to a current
drain of approximately 5 mA drawn from the voltage 5V. Its output impedance is matched to the
second two pole crystal filter FL3102. The signal is further amplified by a pre-amplifier (Q3102)
before going into pin 1 of IFIC (U3101).
A dual hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

2.4

Low Intermediate Frequency (IF) and Receiver Back-End
The 44.85 MHz high-IF signal from the second IF amplifier feeds the IF IC (U3101) at pin 1. Within
the IF IC, the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator (2nd LO)
to produce the low-IF signal at 455 kHz. The 2nd LO frequency is determined by crystal Y3101. The
low IF signal is amplified and filtered by an external pair of 455 kHz ceramic filters FL3112, FL3114

6881091C63-A

VHF (136-174 MHz) 1-25W Transmitter Power Amplifier (PA) 25W

Chapter 4: 2-3

for 20/25 kHz channel spacing or FL3111, FL3113/F3115 for 12.5 kHz channel spacing. These pairs
are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the limiter
input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mVrms (at 60%
deviation) from U3101 pin 8 (DISCAUDIO) which is fed to the ASFIC_CMP (U0221) pin 2 (part of
the Controller circuitry).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101 pin 5, having a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101 pin 63) and in addition is available
at accessory connector J0501-15.

3.0

VHF (136-174 MHz) 1-25W Transmitter Power Amplifier (PA) 25W
The radio’s 25W PA is a three-stage amplifier used to amplify the output from the VCOBIC to the
radio transmit level. All three stages utilize LDMOS technology. The gain of the first stage (U3401)
and the second stage (Q3421) is adjustable, controlled by pin 4 of PCIC (U3501) via U3402-1 and
U3402-2. It is followed by an LDMOS final stage (Q3441).

Devices U3401, Q3421 and Q3441 are surface mounted. A pressure pad between the board and
the radio's cover provides good thermal contact between the devices and the chassis.

3.1

First Power Controlled Stage
The first stage (U3401) is a 20dB gain integrated circuit containing two LDMOS FET amplifier
stages. It amplifies the RF signal from the VCO (TXINJ). The output power of stage U3401 is
controlled by a DC voltage applied to pin 1 from the op-amp U3402-1, pin 1. The control voltage
simultaneously varies the bias of two FET stages within U3401. This biasing point determines the

6881091C63-A

Chapter 4: 2-4

VHF (136-174 MHz) 1-25W Transmitter Power Amplifier (PA)

overall gain of U3401 and therefore its output drive level to Q3421, which in turn controls the output
power of the PA.
Op-amp U3402-1 monitors the drain current of U3401 via resistor R3444 and adjusts the bias
voltage of U3401 so that the current remains constant. The PCIC (U3501) provides a DC output
voltage at pin 4 (INT) which sets the reference voltage of the current control loop. A rising power
output causes the DC voltage from the PCIC to fall, and U3402-1 adjusts the bias voltage for a lower
drain current to lower the gain of the stage.
In receive mode the DC voltage from PCIC pin 23 (RX) turns on Q3442, which in turn switches off
the biasing voltage to U3401.
Switch S3440 is a pressure pad with a conductive strip which connects two conductive areas on the
board when the radio’s cover is properly screwed to the chassis. When the cover is removed, S3440
opens and the resulting high voltage level at the inverting inputs of the current control op-amps
U3402-1 & 2 switches off the biasing of U3401 and Q3421. This prevents transmitter key up while
the devices do not have proper thermal contact to the chassis.

3.2

Power Controlled Driver Stage
The next stage is an LDMOS device (Q3421) providing a gain of 12dB. This device requires a
positive gate bias and a quiescent current flow for proper operation. The bias is set during transmit
mode by the drain current control op-amp U3402-2, and fed to the gate of Q3421 via the resistive
network R3429, R3418, R3415 and R3416.
Op-amp U3402-2 monitors the drain current of U3421 via resistors R3424-27 and adjusts the bias
voltage of Q3421 so that the current remains constant. The PCIC (U3501) provides a DC output
voltage at pin 4 (INT) which sets the reference voltage of the current control loop. A rising power
output causes the DC voltage from the PCIC to fall, and U3402-2 adjusts the bias voltage for a lower
drain current to lower the gain of the stage.
In receive mode the DC voltage from PCIC pin 23 (RX) turns on Q3422, which in turn switches off
the biasing voltage to Q3421.

3.3

Final Stage
The final stage is an LDMOS device (Q3441) providing a gain of 12dB. This device also requires a
positive gate bias and a quiescent current flow for proper operation. The voltage of the line
MOSBIAS_2 is set in transmit mode by the ASFIC and fed to the gate of Q3441 via the resistive
network R3404, R3406, and R3431-5. This bias voltage is tuned in the factory. If the transistor is
replaced, the bias voltage must be tuned using the Customer Programming Software (CPS). Care
must be taken not to damage the device by exceeding the maximum allowed bias voltage. In receive
mode U3402-2 pulls the bias voltage to low via D3401. The device’s drain current is drawn directly
from the radio’s DC supply voltage input, PASUPVLTG, via L3436 and L3437.
A matching network consisting of C3441-49, L3443, and two striplines, transforms the impedance to
50 ohms and feeds the directional coupler.

3.4

Directional Coupler
The directional coupler is a microstrip printed circuit, which couples a small amount of the forward
power delivered by Q3441. The coupled signal is rectified by D3451. The DC voltage is proportional
to the RF output power and feeds the RFIN port of the PCIC (U3501 pin 1). The PCIC controls the
gain of stage U3401 and Q3421 as necessary to hold this voltage constant, thus ensuring the
forward power out of the radio to be held to a constant value.

3.5

Chapter 4: 2-5

Antenna Switch
The antenna switch consists of two PIN diodes, D3471 and D3472. In the receive mode, both diodes
are off. Signals applied at the antenna jack J3401 are routed, via the harmonic filter, through
network L3472, C3474 and C3475, to the receiver input. In the transmit mode, K9V1 turns on
Q3471 which enables current sink Q3472, set to 96 mA by R3473 and VR3471. This completes a
DC path from PASUPVLTG, through L3437, D3471, L3472, D3472, L3471, R3474 and the current
sink, to ground. Both diodes are forward biased into conduction. The transmitter RF from the
directional coupler is routed via D3471 to the harmonic filter and antenna jack. D3472 also
conducts, shunting RF power and preventing it from reaching the receiver port (RXIN). L3472 is
selected to appear as a lambda / 4 wave transmission line, making the short circuit presented by
D3472 appear as an open circuit at the junction of D3472 and the receiver path.

3.6

Harmonic Filter
Components L3491-L3493 and L3472, C3491-C3499 form a Chebychev low-pass filter to attenuate
harmonic energy of the transmitter to specifications level. R3491 is used to drain electrostatic
charge that might otherwise build up on the antenna. The harmonic filter also prevents high level RF
signals above the receiver passband from reaching the receiver circuits, improving spurious
response rejection.

3.7

Power Control
The transmitter uses the Power Control IC (PCIC, U3501) to control the power output of the radio. A
portion of the forward RF power from the transmitter is sampled by the directional coupler and
rectified, to provide a DC voltage to the RFIN port of the PCIC (pin 1) which is proportional to the
sampled RF power.
The ASFIC (U0221) has internal digital-to-analog converters (DACs) which provide a reference
voltage of the control loop to the PCIC via R3505. The reference voltage level is programmable
through the SPI line of the PCIC. This reference voltage is proportional to the desired power setting
of the transmitter, and is factory programmed at several points across the frequency range of the
transmitter to offset frequency response variations of the transmitter’s power detector circuit.
The PCIC provides a DC output voltage at pin 4 (INT) which sets the drain current of the first
(U3401) and second (Q3421) transmitter stage via current control op-amps U3402-1 and U3402-2.
This adjusts the transmitter power output to the intended value. Variations in forward transmitter
power cause the DC voltage at pin 1 to change, and the PCIC adjusts the control voltage above or
below its nominal value to raise or lower output power. Capacitors C3502-4, in conjunction with
resistors and integrators within the PCIC, control the transmitter power-rise (key-up) and powerdecay (de-key) characteristic to minimize splatter into adjacent channels. U3502 is a temperaturesensing device, which monitors the circuit board temperature in the vicinity of the transmitter driver
and final devices, and provides a DC voltage to the PCIC (TEMP, pin 30) proportional to
temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter
output power will be reduced so as to reduce the transmitter temperature.

4.0

VHF (136-174 MHz) 1-25W Frequency Synthesis
The frequency synthesizer subsystem consists of the reference oscillator (Y3261 or Y3263), the
Low Voltage Fractional-N synthesizer (LVFRAC-N, U3201), and the voltage-controlled oscillators
and buffer amplifiers (U3301, Q3301-2 and associated circuitry).

Reference Oscillator
The reference oscillator (Y3263) contains a temperature compensated crystal oscillator with a
frequency of 16.8 MHz. An analog-to-digital (A/D) converter internal to U3201 (LVFRAC-N) and
controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U3201 (pin 25)
to set the frequency of the oscillator. The output of the oscillator (U3263 pin 3) is applied to pin 23
(XTAL1) of U3201 via R3263 and C3235.
In applications where less frequency stability is required, the oscillator inside U3201 is used along
with an external crystal Y3261, varactor diode D3261, C3261, C3262 and R3262. In this case,
Y3263, R3263, C3235 and C3251 are not used. When Y3263 is used, Y3261, D3261, C3261,
C3262 and R3262 are not used, and C3263 is increased to 0.1 uF.

4.2

Fractional-N Synthesizer
The LVFRAC-N synthesizer IC (U3201) consists of a pre-scaler, a programmable loop divider,
control divider logic, a phase detector, a charge pump, an A/D converter for low frequency digital
modulation, a balance attenuator to balance high frequency analog modulation and low frequency
digital modulation, a 13V positive voltage multiplier, a serial interface for control, and finally a super
filter for the regulated 5 volts.

A voltage of 5V applied to the super filter input (U3201 pin 30) supplies an output voltage of 4.5 VDC

charge pump resistor network (R3251, R3252). The synthesizer supply voltage is provided by the
5V regulator U3211.
In order to generate a high voltage to supply the phase detector (charge pump) output stage at

circuitry (D3201, C3202, C3203). This voltage multiplier is basically a diode capacitor network driven
by two (1.05MHz) 180 degrees out of phase signals (U3201-14 and -15).
Output LOCK (U3201-4) provides information about the lock status of the synthesizer loop. A high
level at this output indicates a stable loop. IC U3201 provides the 16.8 MHz reference frequency at
pin 19.

The VCOBIC together with the Fractional-N synthesizer (U3201) generates the required frequencies
in both the transmit and receive modes. The TRB line (U3301 pin 19) determines which tank circuits
and internal buffers are to be enabled. A high level on TRB enables the TX tank and TX output (pin

RF output is routed from U3301 pin 12 (PRESC_OUT), via a low-pass filter, to pin 32 of U3201
(PREIN).

Chapter 4: 2-8

VHF (136-174 MHz) 1-25W Frequency Synthesis

A steering line voltage (VCTRL) between 2.5V and 11V at varactor diode D3361 will tune the full TX
frequency range (TXINJ) from 136 MHz to 174 MHz, and at varactor diode D3341 will tune the full
RX frequency range (RXINJ) from 181 MHz to 219 MHz. The RX tank circuit uses a Hartley
configuration for wider bandwidth. For the RX tank circuit, an external transistor Q3304 is used for
better side-band noise.
The external RX buffers (Q3301 and Q3302) are enabled by a high at U3301 pin 7 (RX_SWITCH)
via transistor switch Q3303. In the TX mode, the modulation signal (VCOMOD) from the LVFRAC-N
synthesizer IC (U3201 pin 41) is applied to varactor diode D3362, which modulates the TX VCO
frequency via capacitor C3362. Varactor D3362 is biased for linearity from VSF.

4.4

Synthesizer Operation
The complete synthesizer subsystem consists of the low voltage FRAC-N (LVFRACN), the
reference oscillator (a crystal oscillator with temperature compensation), charge pump circuitry, loop
filter circuitry and a DC supply. The output signal PRESC from the VCOBIC (U3301 pin 12) is fed to
U3201 pin 32 (PREIN) via a low-pass filter (C3318, L3318 and C3226) which attenuates harmonics
and provides the correct level to close the synthesizer loop.
The pre-scaler in the synthesizer (U3201) is a dual modulus type with selectable divider ratios. The
divider ratio of the pre-scaler is controlled by the loop divider, which in turn receives its inputs via the
SRL. The output of the pre-scaler is applied to the loop divider. The output of the loop divider is
connected to the phase detector, which compares the loop divider’s output signal with the reference
signal. The reference signal is generated by dividing down the signal of the reference oscillator
(Y3261 or Y3263).
The output signal of the phase detector is a pulsed DC signal which is routed to the charge pump.
The charge pump outputs a current at U3201 pin 43 (IOUT). The loop filter (which consists of
R3221-R3223 and C3221-C3224) transforms this current into a voltage that is applied to the
varactor diodes (D3361 for transmit, D3341 for receive) to alter the output frequency of the
appropriate VCO. The current can be set to a value fixed within the LVFRAC-N IC, or to a value
determined by the currents flowing into BIAS 1 (U3201-40) or BIAS 2 (U3201-39). The currents are
set by the value of R3251 and R3252 respectively. The selection of the three different bias sources
is done by software programming.
To reduce synthesizer lock time when new frequency data has been loaded into the synthesizer, the
magnitude of the loop current is increased by enabling the IADAPT pin (U3201-45) for a certain
software programmable time (adapt mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range, the current is determined
only by the resistors connected to BIAS 1 and BIAS 2, or by the internal current source. A settled
synthesizer loop is indicated by a high level signal at U3201-4 (LOCK).
The LOCK signal is routed to one of the µP’s ADC inputs (U0101-56). From the measured voltage,
the µP determines whether LOCK is active.
In order to modulate the PLL, the two spot modulation method is utilized. Via U3201 pin 10
(MODIN), the audio signal is applied to both the A/D converter (low frequency path) as well as the
balance attenuator (high frequency path). The A/D converter changes the low frequency analog
modulating signal into a digital code that is applied to the loop divider, thereby causing the carrier to
deviate. The balance attenuator is used to adjust the VCO’s deviation sensitivity to high frequency
modulating signals. The output of the balance attenuator is present at the MODOUT port (U320141) and connected to the VCO modulation diode D3362 via R3364.

Reference designators with an asterisk indicate
components which are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Section 1. Boards are not
orderable using the 84-prefixed number.

* Motorola Depot Servicing only
Reference designators with an asterisk indicate
components which are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.
†

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Section 1. Boards are not
orderable using the 84-prefixed number.

Reference designators with an asterisk indicate
components which are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Section 1. Boards are not
orderable using the 84-prefixed number.

Introduction
This chapter provides a detailed theory of operation for the UHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

2.0

UHF Band 1 (403-470 MHz) 1-25W Receiver Front-End

2.1

Receiver Front-End
The receiver is able to cover the UHF range from 403 to 470 MHz. It consists of four major blocks:
front-end bandpass filters and pre-amplifier, first mixer, high-IF, low-IF and receiver back-end. Two
varactor-tuned bandpass filters perform antenna signal pre-selection. A passive double-balanced
mixer converts the signal to the first IF of 44.85 MHz. Low-side first injection is used.

Chapter 5: 2-2

UHF Band 1 (403-470 MHz) 1-25W Receiver Front-End

There are two 2-pole 44.85 MHz crystal filters in the high-IF section and 2 pairs of 455 kHz ceramic
filters in the low-IF section to provide the required adjacent channel selectivity. The correct pair of
ceramic filters for 12.5 or 25 kHz channel spacing is selected via control line BWSELECT. The
second IF at 455 kHz is mixed, amplified and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuitry, before being applied to the
receiver pre-selector filter (C4001, C4002, D4001 and associated components). The 2-pole preselector filter tuned by the varactor diodes D4001 and D4002 pre-selects the incoming signal (RXIN)
from the antenna switch to reduce spurious effects to following stages. The tuning voltage
(FECTRL_1) ranging from 2 volts to 8 volts is controlled by pin 20 of PCIC (U4501) in the
Transmitter section. A dual hot carrier diode (D4003) limits any inband signal to 0 dBm to prevent
damage to the pre-amplifier.
The RF pre-amplifier is an SMD device (Q4003) with collector base feedback to stabilize gain,
impedance, and intermodulation. The collector current of approximately 11-16 mA is drawn from the
9.3V supply via L4003 and R4002. A switchable 3dB pad (R4066, R4007, R4063, R4064 and
R4070), controlled via line FECTRL_2 and Q4004 stabilizes the output impedance and
intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
The varactor diodes D4004 and D4005 are controlled by the same signal FECTRL_1, which
controls the pre-selector filter. A following 1 dB pad (R4013 - R4015) stabilizes the output
impedance and intermodulation performance.

2.3

First Mixer and High Intermediate Frequency (IF)
The signal coming from the front-end is converted to the first IF (44.85 MHz) using a passive doublebalanced mixer (D4051). Its ports are matched for incoming RF signal conversion to the 44.85 MHz
IF using low side injection via matching transformers T4051 and T4052. The injection signal (RXINJ)
coming from the RX VCO buffer (Q4332) is filtered by the low-pass filter consisting of (L4053,
L4054, C4053 - C4055) followed by a matching transformer T4052 and has a level of approximately
15dBm.
The mixer IF output signal (IF) from transformer T4501pin 2 is fed to the first two pole crystal filter
FL3101. The filter output in turn is matched to the following IF amplifier.
The IF amplifier Q3101 is actively biased by a collector base feedback (R3101, R3106) to a current
drain of approximately 5 mA drawn from the voltage 5V. Its output impedance is matched to the
second two pole crystal filter FL3102. The signal is further amplified by a pre-amplifier (Q3102)
before going into pin 1 of IFIC (U3101).
A dual hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

Chapter 5: 2-3

Low Intermediate Frequency (IF) and Receiver Back-End
The 44.85 high IF signal from the second IF amplifier feeds the IF IC (U3101) at pin1. Within the IF
IC the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator (2nd LO) to
produce the low IF signal at 455 kHz. The 2nd LO frequency is determined by crystal Y3101. The
low IF signal is amplified and filtered by an external pair of 455 kHz ceramic filters FL3112, FL3114
for 20/25 kHz channel spacing or FL3111, FL3113/F3115 for 12.5 kHz channel spacing. These pairs
are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the limiter
input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U3103 pin 8 (DISCAUDIO) which is fed to the ASFIC_CMP (U0221) pin 2 (part of
the Controller circuitry).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101 pin 5, having a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101 pin 63) and in addition is available
at accessory connector J0501-15.

UHF Band 1 (403-470 MHz) 1-25W Transmitter Power Amplifier
(PA) 25W
The radio’s 25W PA is a three-stage amplifier used to amplify the output from the VCOBIC to the
radio transmit level. All three stages utilize LDMOS technology. The gain of the first stage (U4401) is
adjustable, controlled by pin 4 of PCIC (U4501) via U4402-1. It is followed by an LDMOS stage
(Q4421) and LDMOS final stage (Q4441).

Chapter 5: 2-4

3.1

UHF Band 1 (403-470 MHz) 1-25W Transmitter Power Amplifier (PA) 25W

First Power Controlled Stage
The first stage (U4401) is a 20dB gain integrated circuit containing two LDMOS FET amplifier
stages. It amplifies the RF signal from the VCO (TXINJ). The output power of stage U4401 is
controlled by a DC voltage applied to pin 1 from the op-amp U4402-1, pin 1. The control voltage
simultaneously varies the bias of two FET stages within U4401. This biasing point determines the
overall gain of U4401 and therefore its output drive level to Q4421, which in turn controls the output
power of the PA.
Op-amp U4402-1 monitors the drain current of U4401 via resistor R4444 and adjusts the bias
voltage of U4401 so that the current remains constant. The PCIC (U4501) provides a DC output
voltage at pin 4 (INT) which sets the reference voltage of the current control loop. A rising power
output causes the DC voltage from the PCIC to fall, and U4402-1 adjusts the bias voltage for a lower
drain current to lower the gain of the stage.
In receive mode the DC voltage from PCIC pin 23 (RX) turns on Q4442, which in turn switches off
the biasing voltage to U4401.
Switch S5440 is a pressure pad with a conductive strip which connects two conductive areas on the
board when the radio's cover is properly screwed to the chassis. When the cover is removed, S5440
opens and the resulting high voltage level at the inverting inputs of the current control op-amps
U4402-1 & 2 switches off the biasing of U4401 and Q4421. This prevents transmitter key up while
the devices do not have proper thermal contact to the chassis.

3.2

Power Controlled Driver Stage
The next stage is an LDMOS device (Q4421) providing a gain of 12dB. This device requires a
positive gate bias and a quiescent current flow for proper operation. The bias is set during transmit
mode by the drain current control op-amp U4402-2, and fed to the gate of Q4421 via the resistive
network R4429, R4418, R4415 and R4416.
Op-amp U4402-2 monitors the drain current of U4421 via resistors R4424-27 and adjusts the bias
voltage of Q4421 so that the current remains constant. The PCIC (U4501) provides a DC output
voltage at pin 4 (INT) which sets the reference voltage of the current control loop. A rising power
output causes the DC voltage from the PCIC to fall, and U4402-2 adjusts the bias voltage for a lower
drain current to lower the gain of the stage.
In receive mode the DC voltage from PCIC pin 23 (RX) turns on Q4422, which in turn switches off
the biasing voltage to Q4421.

3.3

Final Stage
The final stage is an LDMOS device (Q4441) providing a gain of 12dB. This device also requires a
positive gate bias and a quiescent current flow for proper operation. The voltage of the line
MOSBIAS_2 is set in transmit mode by the ASFIC and fed to the gate of Q4441 via the resistive
network R4404, R4406, and R4431-2. This bias voltage is tuned in the factory. If the transistor is
replaced, the bias voltage must be tuned using the Global Tuner. Care must be taken not to damage
the device by exceeding the maximum allowed bias voltage. The device’s drain current is drawn
directly from the radio’s DC supply voltage input, PASUPVLTG, via L4436 and L4437.
A matching network consisting of C4441-49 and striplines transforms the impedance to 50 ohms
and feeds the directional coupler.

3.4

Chapter 5: 2-5

Directional Coupler
The directional coupler is a microstrip printed circuit, which couples a small amount of the forward
power delivered by Q4441. The coupled signal is rectified by D4451. The DC voltage is proportional
to the RF output power and feeds the RFIN port of the PCIC (U4501 pin 1). The PCIC controls the
gain of stages U4401 and Q4421 as necessary to hold this voltage constant, thus ensuring the
forward power out of the radio to be held to a constant value.

3.5

Antenna Switch
The antenna switch consists of two PIN diodes, D4471 and D4472. In the receive mode, both diodes
are off. Signals applied at the antenna jack J4401 are routed, via the harmonic filter, through
network L4472, C4474 and C4475, to the receiver input. In the transmit mode, K9V1 turns on
Q4471 which enables current sink Q4472, set to 96 mA by R4473 and VR4471. This completes a
DC path from PASUPVLTG, through L4437, D4471, L4472, D4472, L4471, R4474 and the current
sink, to ground. Both diodes are forward biased into conduction. The transmitter RF from the
directional coupler is routed via D4471 to the harmonic filter and antenna jack. D4472 also
conducts, shunting RF power and preventing it from reaching the receiver port (RXIN). L4472 is
selected to appear as a broadband lambda/4 wave transmission line, making the short circuit
presented by D4472 appear as an open circuit at the junction of D4472 and the receiver path.

3.6

Harmonic Filter
Components L4491-L4493 and L4472, C4491, C4496-98 form a Butterworth low-pass filter to
attenuate harmonic energy of the transmitter to specifications level. R4491 is used to drain
electrostatic charge that might otherwise build up on the antenna. The harmonic filter also prevents
high level RF signals above the receiver passband from reaching the receiver circuits, improving
spurious response rejection.

3.7

Power Control
The transmitter uses the Power Control IC (PCIC, U4501) to control the power output of the radio. A
portion of the forward RF power from the transmitter is sampled by the directional coupler and
rectified, to provide a DC voltage to the RFIN port of the PCIC (pin 1) which is proportional to the
sampled RF power.
The ASFIC (U0221) has internal digital-to-analog converters (DACs) which provide a reference
voltage of the control loop to the PCIC via R4505. The reference voltage level is programmable
through the SPI line of the PCIC. This reference voltage is proportional to the desired power setting
of the transmitter, and is factory programmed at several points across the frequency range of the
transmitter to offset frequency response variations of the transmitter’s power detector circuit.
The PCIC provides a DC output voltage at pin 4 (INT) which sets the drain current of the first
(U4401) and second (Q4421) transmitter stage via current control op-amps U3402-1 and U3402-2.
This adjusts the transmitter power output to the intended value. Variations in forward transmitter
power cause the DC voltage at pin 1 to change, and the PCIC adjusts the control voltage above or
below its nominal value to raise or lower output power.
Capacitors C4502-4, in conjunction with resistors and integrators within the PCIC, control the
transmitter power-rise (key-up) and power-decay (de-key) characteristic to minimize splatter into
adjacent channels.

UHF Band 1 (403-470 MHz) 1-25W Frequency Synthesis

U4502 is a temperature-sensing device, which monitors the circuit board temperature in the vicinity
of the transmitter driver and final devices, and provides a DC voltage to the PCIC (TEMP, pin 30)
proportional to temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the
transmitter output power will be reduced so as to reduce the transmitter temperature.

4.0

UHF Band 1 (403-470 MHz) 1-25W Frequency Synthesis
The synthesizer subsystem consists of the reference oscillator (Y4261 or Y4262), the Low Voltage
Fractional-N synthesizer (LVFRAC-N, U4201), and the Voltage Controlled Oscillator VCO.

4.1

Reference Oscillator
The reference oscillator (Y4262) contains a temperature compensated crystal oscillator with a
frequency of 16.8 MHz. An analog-to-digital (A/D) converter internal to U4201 (LVFRAC-N) and
controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U4201 pin 25 to
set the frequency of the oscillator. The output of the oscillator (pin 3 of Y4262) is applied to pin 23
(XTAL1) of U4201 via a RC series combination.
In applications where less frequency stability is required the oscillator inside U4201 is used along
with an external crystal Y4261, varactor diode D4261, C4261, C4262 and R4262. In this case,
Y4262, R4263, C4235 and C4251 are not used. When Y4262 is used, Y4261, D4261, C4261,
C4262 and R4262 are not used, and C4263 is increased to 0.1 uF.

4.2

Fractional-N Synthesizer
The LVFRAC-N synthesizer IC (U4201) consists of a pre-scaler, a programmable loop divider,
control divider logic, a phase detector, a charge pump, an A/D converter for low frequency digital
modulation, a balance attenuator to balance high frequency analog modulation and low frequency
digital modulation, a 13V positive voltage multiplier, a serial interface for control, and finally a super
filter for the regulated 5 volts.

VDC(VSF) at pin 28. It supplies the VCO, VCO modulation bias circuit (via R4322) and the
synthesizer charge pump resistor network (R4251, R4252). The synthesizer supply voltage is
provided by the 5V regulator U4211.
In order to generate a high voltage to supply the phase detector (charge pump) output stage at
pin 47 VCP (U4201-47), a voltage of 13 VDC is being generated by the positive voltage multiplier
circuitry (D4201, C4202, C4203). This voltage multiplier is basically a diode capacitor network driven
by two (1.05MHz) 180 degrees out of phase signals (U4201-14 and -15).
Output LOCK (U4201-4) provides information about the lock status of the synthesizer loop. A high
level at this output indicates a stable loop. IC U4201 provides the 16.8 MHz reference frequency at
pin 19.
The serial interface (SRL) is connected to the µP via the data line DATA (U4201-7), clock line CLK
(U4201-8), and chip enable line CSX (U4201-9).

Figure 5-4 UHF VCO Block Diagram
The VCOBIC together with Fractional-N synthesizer (U4201) generates the required frequencies in
both transmit and receive modes. The TRB line (U4301 pin 19) determines which tank circuits and
internal buffers are to be enabled. A high level on TRB enables TX tank and TX output (pin 10), and
a low enables RX tank and RX output (pin 8). A sample of the signal from the enabled output is
routed from U4301 pin 12 (PRESC_OUT), via a low-pass filter, to pin 32 of U4201 (PREIN).
A steering line voltage (VCTRL) between 3.0V and 10.0V at varactor diode CR4311 will tune the full
TX frequency range (TXINJ) from 403 MHz to 470 MHz, and at varactor diodes CR4301, CR4302
and CR4303 will tune the full RX frequency range (RXINJ) from 358 MHz to 425 MHz. The tank
circuits uses the Hartley configuration for wider bandwidth. For the RX tank circuit, an external
transistor Q4301 is used in conjunction with the internal transistor for better side-band noise.

Chapter 5: 2-9

The external RX buffers (Q4332) are enabled by a high at U4201 pin 3 (AUX4) via transistor switch
Q4333. In TX mode the modulation signal (VCOMOD) from the LVFRAC-N synthesizer IC (U4201
pin41) is applied modulation circuitry CR4321, R4321, R4322 and C4324, which modulates the TX
VCO frequency via coupling capacitor C4321. Varactor CR4321 is biased for linearity from VSF.

4.4

Synthesizer Operation
The complete synthesizer subsystem comprises mainly of low voltage FRAC-N (LVFRACN) IC,
Reference Oscillator (crystal oscillator with temperature compensation), charge pump circuitry, loop
filter circuitry and DC supply. The output signal PRESC_OUT of the VCOBIC (U4301 pin 12) is fed
to pin 32 of U4201 (PREIN) via a low-pass filter (C4229, L4225) which attenuates harmonics and
provides the correct level to close the synthesizer loop.
The pre-scaler in the synthesizer (U4201) is basically a dual modulus pre-scaler with selectable
divider ratios. This divider ratio of the pre-scaler is controlled by the loop divider, which in turn
receives its inputs via the SRL. The output of the pre-scaler is applied to the loop divider. The output
of the loop divider is connected to the phase detector, which compares the loop divider’s output
signal with the reference signal. The reference signal is generated by dividing down the signal of the
reference oscillator (Y4261 or Y4262).
The output signal of the phase detector is a pulsed DC signal which is routed to the charge pump.
The charge pump outputs a current at pin 43 of U4201 (IOUT). The loop filter (which consists of
R4221-R4223, C4221-C4225,L4221) transforms this current into a voltage that is applied to the
varactor diodes CR4311 for transmit, CR4301, CR4302 & CR4303 for receive and alters the output
frequency of the VCO. The current can be set to a value fixed in the LVFRAC-N IC or to a value
determined by the currents flowing into BIAS 1 (U4201-40) or BIAS 2 (U4201-39). The currents are
set by the value of R4251 or R4252 respectively. The selection of the three different bias sources is
done by software programming.
To reduce synthesizer lock time when new frequency data has been loaded into the synthesizer the
magnitude of the loop current is increased by enabling the IADAPT (U4201-45) for a certain
software programmable time (Adapt Mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range the current is determined
only by the resistors connected to BIAS 1, BIAS 2, or the internal current source. A settled
synthesizer loop is indicated by a high level of signal LOCK (U4201-4).
The LOCK (U4201-4) signal is routed to one of the µP’s ADCs input U101-56. From the voltage the
µP determines whether LOCK is active. In order to modulate the PLL the two spot modulation
method is utilized. Via pin 10 (MODIN) on U4201 the audio signal is applied to both the A/D
converter (low freq path) as well as the balance attenuator (high freq path). The A/D converter
converts the low frequency analog modulating signal into a digital code that is applied to the loop
divider, thereby causing the carrier to deviate. The balance attenuator is used to adjust the VCO’s
deviation sensitivity to high frequency modulating signals. The output of the balance attenuator is
present at the MODOUT port (U4201-41) and connected to the VCO modulation diode CR4321 via
R4321, C4325.

* Motorola Depot Servicing only
Reference designators with an asterisk indicate
components which are not field replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.
†

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Section 1. Boards are not
orderable using the 84-prefixed number.

THEORY OF OPERATION

Introduction
This chapter provides a detailed theory of operation for the UHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

2.0

UHF Band 2 (450-512/527 MHz) 1-25W Receiver Front-End

2.1

Receiver Front-End
The receiver is able to cover the UHF range from 450 to 512 MHz (for CDM models) and from 450 to
527 MHz (for PRO models). It consists of four major blocks: front-end bandpass filters and preamplifier, first mixer, high-IF, low-IF and receiver back-end. Two varactor-tuned bandpass filters
perform antenna signal pre-selection. A passive double-balanced mixer converts the signal to the
first IF of 44.85 MHz. Low-side first injection is used.

Chapter 6: 2-2

UHF Band 2 (450-512/527 MHz) 1-25W Receiver Front-End

There are two 2-pole 44.85 MHz crystal filters in the high-IF section and 2 pairs of 455 kHz ceramic
filters in the low-IF section to provide the required adjacent channel selectivity. The correct pair of
ceramic filters for 12.5 or 25 kHz channel spacing is selected via control line BWSELECT. The
second IF at 455 kHz is mixed, amplified and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuitry, before being applied to the
receiver pre-selector filter (C5001, C5002, D5001 and associated components). The 2-pole preselector filter tuned by the varactor diodes D5001 and D5002 pre-selects the incoming signal (RXIN)
from the antenna switch to reduce spurious effects to following stages. The tuning voltage
(FECTRL_1) ranging from 2 volts to 8 volts is controlled by pin 20 of PCIC (U5501) in the
Transmitter section. A dual hot carrier diode (D5003) limits any inband signal to 0 dBm to prevent
damage to the pre-amplifier.
The RF pre-amplifier is an SMD device (Q5003) with collector base feedback to stabilize gain,
impedance, and intermodulation. The collector current of approximately 11-16 mA is drawn from the
9.3V supply via L5003 and R5002. A switchable 3dB pad (R5066, R5007, R5063, R5064 and
R5070), controlled via line FECTRL_2 and Q5004 stabilizes the output impedance and
intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
The varactor diodes D5004 and D5005 are controlled by the same signal FECTRL_1, which
controls the pre-selector filter. A following 1 dB pad (R5013 - R5015) stabilizes the output
impedance and intermodulation performance.

2.3

First Mixer and High Intermediate Frequency (IF)
The signal coming from the front-end is converted to the first IF (44.85 MHz) using a passive doublebalanced mixer (D5051). Its ports are matched for incoming RF signal conversion to the 44.85 MHz
IF using low side injection via matching transformers T5051 and T5052. The injection signal (RXINJ)
coming from the RX VCO buffer (Q5332) is filtered by the low-pass filter consisting of (L5053,
L5054, C5053 - C5055) followed by a matching transformer T5052 and has a level of approximately
15dBm.
The mixer IF output signal (IF) from transformer T5501 pin 2 is fed to the first two pole crystal filter
FL3101. The filter output in turn is matched to the following IF amplifier.
The IF amplifier Q3101 is actively biased by a collector base feedback (R3101, R3106) to a current
drain of approximately 5 mA drawn from the voltage 5V. Its output impedance is matched to the
second 2-pole crystal filter FL3102. The signal is further amplified by a pre-amplifier (Q3102) before
going into pin 1 of IFIC (U3101).
A dual hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

Chapter 6: 2-3

Low Intermediate Frequency (IF) and Receiver Back-End
The 44.85 high IF signal from the second IF amplifier feeds the IF IC (U3101) at pin 1. Within the IF
IC the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator (2nd LO) to
produce the low IF signal at 455 kHz. The 2nd LO frequency is determined by crystal Y3101. The
low IF signal is amplified and filtered by an external pair of 455 kHz ceramic filters FL3112, FL3114
for 20/25 kHz channel spacing or FL3111, FL3113/F3115 for 12.5 kHz channel spacing. These pairs
are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the limiter
input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U3103 pin 8 (DISCAUDIO) which is fed to the ASFIC_CMP (U0221) pin 2 (part of
the Controller circuitry).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101 pin 5, having a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101 pin 63) and in addition is available
at accessory connector J0501-15.

3.0

UHF Band 2 (450-512/527 MHz) 1-25W Transmitter Power
Amplifier (PA) 25W
The radio’s 25W PA is a three-stage amplifier used to amplify the output from the VCOBIC to the
radio transmit level. All three stages utilize LDMOS technology. The gain of the first stage (U5401) is
adjustable, controlled by pin 4 of PCIC (U5501) via U5402-1. It is followed by an LDMOS stage
(Q5421) and LDMOS final stage (Q5441).

3.1

UHF Band 2 (450-512/527 MHz) 1-25W Transmitter Power Amplifier (PA) 25W

First Power Controlled Stage
The first stage (U5401) is a 20dB gain integrated circuit containing two LDMOS FET amplifier
stages. It amplifies the RF signal from the VCO (TXINJ). The output power of stage U5401 is
controlled by a DC voltage applied to pin 1 from the op-amp U5402-1, pin 1. The control voltage
simultaneously varies the bias of two FET stages within U5401. This biasing point determines the
overall gain of U5401 and therefore its output drive level to Q5421, which in turn controls the output
power of the PA.
Op-amp U5402-1 monitors the drain current of U5401 via resistor R5444 and adjusts the bias
voltage of U5401 so that the current remains constant. The PCIC (U5501) provides a DC output
voltage at pin 4 (INT) which sets the reference voltage of the current control loop. A rising power
output causes the DC voltage from the PCIC to fall, and U5402-1 adjusts the bias voltage for a lower
drain current to lower the gain of the stage.
In receive mode the DC voltage from PCIC pin 23 (RX) turns on Q5442, which in turn switches off
the biasing voltage to U5401.
Switch S5440 is a pressure pad with a conductive strip which connects two conductive areas on the
board when the radio's cover is properly screwed to the chassis. When the cover is removed, S5440
opens and the resulting high voltage level at the inverting inputs of the current control op-amps
U5402-1 & 2 switches off the biasing of U5401 and Q5421. This prevents transmitter key up while
the devices do not have proper thermal contact to the chassis.

3.2

Power Controlled Driver Stage
The next stage is an LDMOS device (Q5421) providing a gain of 12dB. This device requires a
positive gate bias and a quiescent current flow for proper operation. The bias is set during transmit
mode by the drain current control op-amp U5402-2, and fed to the gate of Q5421 via the resistive
network R5429, R5418, R5415 and R5416.
Op-amp U5402-2 monitors the drain current of U5421 via resistors R5424-27 and adjusts the bias
voltage of Q5421 so that the current remains constant. The PCIC (U5501) provides a DC output
voltage at pin 4 (INT) which sets the reference voltage of the current control loop. A rising power
output causes the DC voltage from the PCIC to fall, and U5402-2 adjusts the bias voltage for a lower
drain current to lower the gain of the stage.
In receive mode the DC voltage from PCIC pin 23 (RX) turns on Q5422, which in turn switches off
the biasing voltage to Q5421.

3.3

Final Stage
The final stage is an LDMOS device (Q5441) providing a gain of 12dB. This device also requires a
positive gate bias and a quiescent current flow for proper operation. The voltage of the line
MOSBIAS_2 is set in transmit mode by the ASFIC and fed to the gate of Q5441 via the resistive
network R5404, R5406, and R5431-2. This bias voltage is tuned in the factory. If the transistor is
replaced, the bias voltage must be tuned using the Global Tuner. Care must be taken not to damage
the device by exceeding the maximum allowed bias voltage. The device’s drain current is drawn
directly from the radio’s DC supply voltage input, PASUPVLTG, via L5436 and L5437.
A matching network consisting of C5441-49 and striplines transforms the impedance to 50 ohms
and feeds the directional coupler.

Chapter 6: 2-5

Directional Coupler
The directional coupler is a microstrip printed circuit, which couples a small amount of the forward
power delivered by Q5441. The coupled signal is rectified by D5451. The DC voltage is proportional
to the RF output power and feeds the RFIN port of the PCIC (U5501 pin 1). The PCIC controls the
gain of stages U5401 and Q5421 as necessary to hold this voltage constant, thus ensuring the
forward power out of the radio to be held to a constant value.

3.5

Antenna Switch
The antenna switch consists of two PIN diodes, D5471 and D5472. In the receive mode, both diodes
are off. Signals applied at the antenna jack J5401 are routed, via the harmonic filter, through
network L5472, C5474 and C5475, to the receiver input. In the transmit mode, K9V1 turns on
Q5471 which enables current sink Q5472, set to 96 mA by R5473 and VR5471. This completes a
DC path from PASUPVLTG, through L5437, D5471, L5472, D5472, L5471, R5474 and the current
sink, to ground. Both diodes are forward biased into conduction. The transmitter RF from the
directional coupler is routed via D5471 to the harmonic filter and antenna jack. D5472 also
conducts, shunting RF power and preventing it from reaching the receiver port (RXIN). L5472 is
selected to appear as a broadband lambda/4 wave transmission line, making the short circuit
presented by D5472 appear as an open circuit at the junction of D5472 and the receiver path.

3.6

Harmonic Filter
Components L5491-L5493 and L5472, C5491, C5496-98 form a Butterworth low-pass filter to
attenuate harmonic energy of the transmitter to specifications level. R5491 is used to drain
electrostatic charge that might otherwise build up on the antenna. The harmonic filter also prevents
high level RF signals above the receiver passband from reaching the receiver circuits, improving
spurious response rejection.

3.7

Power Control
The transmitter uses the Power Control IC (PCIC, U5501) to control the power output of the radio. A
portion of the forward RF power from the transmitter is sampled by the directional coupler and
rectified, to provide a DC voltage to the RFIN port of the PCIC (pin 1) which is proportional to the
sampled RF power.
The ASFIC (U0221) has internal digital-to-analog converters (DACs) which provide a reference
voltage of the control loop to the PCIC via R5505. The reference voltage level is programmable
through the SPI line of the PCIC. This reference voltage is proportional to the desired power setting
of the transmitter, and is factory programmed at several points across the frequency range of the
transmitter to offset frequency response variations of the transmitter’s power detector circuit.
The PCIC provides a DC output voltage at pin 4 (INT) which sets the drain current of the first
(U5401) and second (Q5421) transmitter stage via current control op-amps U5402-1 and U5402-2.
This adjusts the transmitter power output to the intended value. Variations in forward transmitter
power cause the DC voltage at pin 1 to change, and the PCIC adjusts the control voltage above or
below its nominal value to raise or lower output power.
Capacitors C5502-4, in conjunction with resistors and integrators within the PCIC, control the
transmitter power-rise (key-up) and power-decay (de-key) characteristic to minimize splatter into
adjacent channels.

UHF Band 2 (450-512/527 MHz) 1-25W Frequency Synthesis

U5502 is a temperature-sensing device, which monitors the circuit board temperature in the vicinity
of the transmitter driver and final devices, and provides a DC voltage to the PCIC (TEMP, pin 30)
proportional to temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the
transmitter output power will be reduced so as to reduce the transmitter temperature.

4.0

UHF Band 2 (450-512/527 MHz) 1-25W Frequency Synthesis
The synthesizer subsystem consists of the reference oscillator (Y5261 or Y5262), the Low Voltage
Fractional-N synthesizer (LVFRAC-N, U5201), and the Voltage Controlled Oscillator VCO.

4.1

Reference Oscillator
The reference oscillator (Y5262) contains a temperature compensated crystal oscillator with a
frequency of 16.8 MHz. An analog-to-digital (A/D) converter internal to U5201 (LVFRAC-N) and
controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U5201 pin 25 to
set the frequency of the oscillator. The output of the oscillator (pin 3 of Y5262) is applied to pin 23
(XTAL1) of U5201 via a RC series combination.
In applications where less frequency stability is required the oscillator inside U5201 is used along
with an external crystal Y5261, varactor diode D5261, C5261, C5262 and R5262. In this case,
Y5262, R5263, C5235 and C5251 are not used. When Y5262 is used, Y5261, D5261, C5261,
C5262 and R5262 are not used, and C5263 is increased to 0.1 uF.

4.2

Fractional-N Synthesizer
The LVFRAC-N synthesizer IC (U5201) consists of a pre-scaler, a programmable loop divider,
control divider logic, a phase detector, a charge pump, an A/D converter for low frequency digital
modulation, a balance attenuator to balance high frequency analog modulation and low frequency
digital modulation, a 13V positive voltage multiplier, a serial interface for control, and finally a super
filter for the regulated 5 volts.

Figure 6-3 UHF Synthesizer Block Diagram
A voltage of 5V applied to the super filter input (U5201 pin 30) supplies an output voltage of 4.5
VDC(VSF) at pin 28. It supplies the VCO, VCO modulation bias circuit (via R5322) and the
synthesizer charge pump resistor network (R5251, R5252). The synthesizer supply voltage is
provided by the 5V regulator U5211.
In order to generate a high voltage to supply the phase detector (charge pump) output stage at
pin 47 VCP (U5201-47), a voltage of 13 VDC is being generated by the positive voltage multiplier
circuitry (D5201, C5202, C5203). This voltage multiplier is basically a diode capacitor network driven
by two (1.05MHz) 180 degrees out of phase signals (U5201-14 and -15).
Output LOCK (U5201-4) provides information about the lock status of the synthesizer loop. A high
level at this output indicates a stable loop. IC U5201 provides the 16.8 MHz reference frequency at
pin 19.
The serial interface (SRL) is connected to the µP via the data line DATA (U5201-7), clock line CLK
(U5201-8), and chip enable line CSX (U5201-9).

Figure 6-4 UHF VCO Block Diagram
The VCOBIC together with Fractional-N synthesizer (U5201) generates the required frequencies in
both transmit and receive modes. The TRB line (U5301 pin 19) determines which tank circuits and
internal buffers are to be enabled. A high level on TRB enables TX tank and TX output (pin 10), and
a low enables RX tank and RX output (pin 8). A sample of the signal from the enabled output is
routed from U5301 pin 12 (PRESC_OUT), via a low-pass filter, to pin 32 of U5201 (PREIN).
A steering line voltage (VCTRL) between 3.0V and 10.0V at varactor diode CR5311 will tune the full
TX frequency range (TXINJ) from 450 MHz to 512 (or 527) MHz, and at varactor diodes CR5301,
CR5302 and CR5303 will tune the full RX frequency range (RXINJ) from 405 MHz to 482 MHz. The
tank circuits uses the Hartley configuration for wider bandwidth. For the RX tank circuit, an external
transistor Q5301 is used in conjunction with the internal transistor for better side-band noise.
Similarly, an external transistor Q5311 is used in the TX tank circuit.

The external RX buffers (Q5332) are enabled by a high at U5201 pin 3 (AUX4) via transistor switch
Q5333. In TX mode the modulation signal (VCOMOD) from the LVFRAC-N synthesizer IC (U5201
pin41) is applied modulation circuitry CR5321, R5321, R5322 and C5324, which modulates the TX
VCO frequency via coupling capacitor C5321. Varactor CR5321 is biased for linearity from VSF.

4.4

Synthesizer Operation
The complete synthesizer subsystem comprises mainly of low voltage FRAC-N (LVFRACN) IC,
Reference Oscillator (crystal oscillator with temperature compensation), charge pump circuitry, loop
filter circuitry and DC supply. The output signal PRESC_OUT of the VCOBIC (U5301 pin 12) is fed
to pin 32 of U5201 (PREIN) via a low-pass filter (C5229, L5225) which attenuates harmonics and
provides the correct level to close the synthesizer loop.
The pre-scaler in the synthesizer (U5201) is basically a dual modulus pre-scaler with selectable
divider ratios. This divider ratio of the pre-scaler is controlled by the loop divider, which in turn
receives its inputs via the SRL. The output of the pre-scaler is applied to the loop divider. The output
of the loop divider is connected to the phase detector, which compares the loop divider’s output
signal with the reference signal. The reference signal is generated by dividing down the signal of the
reference oscillator (Y5261 or Y5262).
The output signal of the phase detector is a pulsed DC signal which is routed to the charge pump.
The charge pump outputs a current at pin 43 of U5201 (IOUT). The loop filter (which consists of
R5221-R5223, C5221-C5225,L5221) transforms this current into a voltage that is applied to the
varactor diodes CR5311 for transmit, CR5301, CR5302 & CR5303 for receive and alters the output
frequency of the VCO. The current can be set to a value fixed in the LVFRAC-N IC or to a value
determined by the currents flowing into BIAS 1 (U5201-40) or BIAS 2 (U5201-39). The currents are
set by the value of R5251 or R5252 respectively. The selection of the three different bias sources is
done by software programming.
To reduce synthesizer lock time when new frequency data has been loaded into the synthesizer the
magnitude of the loop current is increased by enabling the IADAPT (U5201-45) for a certain
software programmable time (Adapt Mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range the current is determined
only by the resistors connected to BIAS 1, BIAS 2, or the internal current source. A settled
synthesizer loop is indicated by a high level of signal LOCK (U5201-4).
The LOCK (U5201-4) signal is routed to one of the µP’s ADCs input U101-56. From the voltage the
µP determines whether LOCK is active. In order to modulate the PLL the two spot modulation
method is utilized. Via pin 10 (MODIN) on U5201 the audio signal is applied to both the A/D
converter (low freq path) as well as the balance attenuator (high freq path). The A/D converter
converts the low frequency analog modulating signal into a digital code that is applied to the loop
divider, thereby causing the carrier to deviate. The balance attenuator is used to adjust the VCO’s
deviation sensitivity to high frequency modulating signals. The output of the balance attenuator is
present at the MODOUT port (U5201-41) and connected to the VCO modulation diode CR5321 via
R5321, C5325.

Section 2
THEORY OF OPERATION
1.0

Introduction
This chapter provides a detailed theory of operation for the low band circuits in the radio. For details
of the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

2.0

Low Band Receiver Front-End

2.1

Receiver Front-End
The low band receiver, shown in Figure 7-1, is bandsplit into three ranges depending on radio
model, covering frequencies from 29.7 to 36.0 MHz, 36.0 to 42.0 MHz, or 42.0 to 50.0 MHz. The
circuitry of the three models is identical except for component value differences. The receiver
consists of five major blocks: front-end bandpass filters and pre-amplifier, first mixer, high-IF and
blanker switches, low-IF and receiver back-end, and “Extender” (noise blanker). Two fixed-tuned
bandpass filters perform antenna signal pre-selection. A passive double-balanced mixer converts
the signal to the high-IF of 10.7 MHz. High-side first injection is used.

Chapter 7: 2-2

Low Band Receiver Front-End

There are two 2-pole 10.7 MHz crystal filters in the high-IF section and two switched pairs of 455
kHz ceramic filters in the low-IF section to provide the required adjacent channel selectivity. The
second IF at 455 kHz is mixed, amplified and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuits, before being applied to the
receiver 5-pole antenna filter (L1001-L1005 and associated components). This filter configuration
provides more rapid attenuation above the passband to provide better rejection of the half-IF
spurious response. A dual hot carrier diode (D1001) limits any inband signal to 0 dBm to prevent
damage to the RF pre-amplifier.
The RF pre-amplifier is an SMD device (Q1001) with collector-base feedback to stabilize gain,
impedance, and intermodulation. Transistor Q1002 compares the voltage drop across resistor
R1005 with a fixed base voltage from divider R1006 and R1007, and adjusts the base current of
Q1001 as necessary to maintain its collector current constant at 25 mA. Operating voltage is from
the regulated 9.3V supply (9V3). During transmit, 9.1 volts (9T1) turns on both transistors in U1001,
turning off Q1003 and therefore Q1001-2. This protects the RF pre-amplifier from excessive
dissipation during transmit mode.
A second 5-pole fixed-tuned bandpass filter provides additional filtering of the amplified signal. This
filter configuration also provides steeper attenuation above its passband for best half-IF attenuation.

2.3

First Mixer and High Intermediate Frequency (IF)
The signal coming from the front-end is converted to the high-IF frequency of 10.7 MHz using a
passive double-balanced mixer (U1051). The high-side injection signal (RXINJ) from the frequency
synthesizer circuitry is filtered by a 7-pole low-pass filter (L1012-14 and associated circuitry) which
removes second harmonic content from the injection signal and improves half-IF rejection. The 50ohm output of the first mixer is applied to the input of the high-IF circuit block.

2.4

High Intermediate Frequency (IF) and Blanker Switches
The first mixer IF output signal (IF) is applied to diplexer network consisting of L1101, L1111 and
associated components. This network has three functions: it terminates the mixer output at
frequencies other than 10.7 MHz into 51-ohm resistor R1101; it matches the 50-ohm mixer output to
the first IF amplifier (Q1101) input; and it provides bandpass filtering at 10.7 MHz to prevent the 5.35
MHz half-IF component of the mixer output from creating a second harmonic at 10.7 MHz in Q1101,
which degrades half-IF rejection.
The IF amplifier Q1101 uses AC and DC feedback to stabilize gain and quiescent current
(approximately 28 mA). Operating voltage is from the regulated 9.3V supply (9V3). Its output is
applied to a 10.7 MHz ceramic filter FL1101 which has a 3 dB bandwidth of 270 kHz and provides a
time delay of 2.6 usec. This delay allows enough time for the “Extender” to respond to impulse noise
present at the input of Q1101 and operate the blanker switches Q1102 and Q1103, muting the IF
signal for the duration of the noise pulse. L1104 and L1105 also provide additional selectivity and
time delay. Operation of the “Extender” circuit is explained in Section 2.6 below.
When the blanker switches turn “on” to mute the IF signal, they momentarily change the impedance
of resonant circuits L1104 and L1105 from high to very low. This abrupt impedance change, if

presented to the high-Q crystal filter FL1102, would cause ringing of the filter response, stretching
an otherwise narrow impulse into a long and audible output waveform. Therefore, source follower
stage Q1104 isolates the blanker switches from the crystal filters, providing a consistent source
impedance via matching network L1106, L1107 and associated components. Q1104 has unity
voltage gain in this configuration.
Crystal filter F1102 is a module which consists of two 2-pole, 10.7 MHz units configured to provide
an overall 4-pole response having a 3 dB bandwidth of approximately 12 kHz. The output is
amplified by second IF amplifier Q1106 and applied to the low-IF circuitry, pin 1 of IF IC (U1103). A
dual hot carrier diode (D1101) limits the amplifier output voltage swing to prevent overdriving the IF
IC at RF input levels above -27 dBm.

2.5

Low Intermediate Frequency (IF) and Receiver Back-End
The 10.7 MHz high-IF signal from the second IF amplifier feeds the IF IC (U1103) at pin 1. Within the
IF IC, the 10.7 MHz high-IF signal mixes with the 10.245 MHz second local oscillator (2nd LO) to
produce the low-IF signal at 455 kHz. The 2nd LO frequency is determined by crystal Y1101. The
low-IF signal is amplified and filtered by external pairs of 455 kHz ceramic filters (FL1105 and
FL1107 for 20 kHz1 channel spacing, or FL1104 and FL1106 for 12.5 kHz channel spacing).
Selection of the appropriate filter pair is accomplished by U1101 and U1102, controlled by the
BWSELECT line from pin 48 of the synthesizer IC U1201. The filtered output from the ceramic filters
is applied to the limiter input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y1102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U1103 pin 8 (AUDIOOUT) which is fed to the ASFIC_CMP (U0221) pin 2 (part of the
controller circuitry).
A Receive Signal Strength Indicator (RSSI) signal is available at U1103 pin 5, having a dynamic
range of 70 dB. The RSSI is interpreted by the µP (U0101 pin 63) and in addition is available at
accessory connector J0501-15.

2.6

“Extender” (Noise Blanker)
The 10.7 MHz output from the first mixer, which is present at the input of the first IF amp Q1101, is
also routed to the input of the “Extender” (noise blanker) circuitry and amplified by FET Q1610. The
high input impedance of the FET stage minimizes loading of the signal in the receiver path. The
output of Q1610 is further amplified by U1601, which is a wide-bandwidth, high gain differential
amplifier (used in a single-ended configuration) incorporating an AGC gain control input. This gain
block provides linear amplification of the instantaneous amplitude of the 10.7 MHz signal at the first
mixer output. The output of U1601 is coupled to biased-detector Q1603. The bias is set so that
noise impulses of a significant amplitude cause Q1603 to conduct. The following stages (Q1604
through Q1606) provide additional gain and pulse shaping which slows the turn-on and turn-off
waveform applied to IF blanker switches Q1102 and Q1103. The result is that, for each noise
impulse, the IF signal is smoothly ramped off and then on again, preventing the pulse from reaching
the narrow IF selectivity, where ringing would cause an objectionable spike at the detector of a much
longer duration than the original impulse.
If the repetition rate of noise impulses is so rapid that the noise blanker can no longer blank them
individually, as indicated by a large increase in high-frequency content at the output of Q1604, stage
Q1607 amplifies this level and turns on level detector Q1609. Its output is highly filtered into a DC
voltage level which is proportional to the repetition rate of noise impulses, and this is applied to the

AGC input pin 5 of U1601, reducing its gain and therefore the amount of noise pulses which are

3.0

Low Band Transmitter Power Amplifier (PA) 60W
The radio’s 60W power amplifier (PA), shown in Figure 7-2, is a three-stage amplifier used to amplify
the output from the VCO to the radio transmit level. The line-up consists of three stages which utilize
LDMOS technology. The first stage is a pre-driver (U1401) that is controlled by pin 4 of PCIC
(U1503) via Q1504 and Q1505 (CNTLVLTG). It is followed by driver stage Q1401, and final stage
utilizing two devices (Q1402 and Q1403) connected in parallel. Q1402 and Q1403 are in direct
contact with the heat sink.
To prevent damage to the final stage devices, a safety switch has been installed to prevent the
transmitter from being keyed with the cover removed.

Power Controlled Stage
The first stage (U1401) is a 20dB gain integrated circuit containing two LDMOS FET amplifier
stages. It amplifies the RF signal from the VCO (TXINJ). The output power of stage U1401 is
controlled by a DC voltage applied to pin 1 from the power control circuit (U1503 pin 4, with
transistors Q1504-5 providing current gain and level-shifting). The control voltage simultaneously
varies the bias of two FET stages within U1401. This biasing point determines the overall gain of
U1401 and therefore its output drive level to Q1401, which in turn controls the output power of the
PA.

Low Band Transmitter Power Amplifier (PA) 60W

3.2

Chapter 7: 2-5

Driver Stage
The next stage is an LDMOS device (Q1401) providing a gain of 13dB. This device requires a
positive gate bias and a quiescent current flow for proper operation. The voltage of the line
MOSBIAS_1 is set during transmit mode by the PCIC pin 24, and fed to the gate of Q1401 via
resistors R1402, R1447, R1449, R1458, R1459, and R1463. The bias voltage is tuned in the factory.
The circuitry associated with U1402-2 and Q1404 limits the variation in the output power of the
driver stage resulting from changes in the input impedance of the final stage due to changes at the
antenna of the radio. The variation in the driver’s output power is limited by controlling its DC
current. The driver’s DC current is monitored by measuring the voltage drop across current-sense
resistors R1473-6, and this voltage is compared to a reference voltage on pin 6 of U1402-2. If the
current through the sense resistors decreases, the circuit increases the bias voltage on the gate of
Q1401 via Q1404. If the current increases, then the bias voltage decreases in order to keep the
driver’s current constant. Since the current must increase with increasing control voltage, an input
path is provided to U1402-2 pin 5 from control line VCNTRL to enable this.

3.3

Final Stage
The final stage uses two LDMOS FET devices operating in parallel. Each device has its own
adjustable gate bias voltage, MOSBIAS_2 and MOSBIAS_3, obtained from D/A outputs of the
ASFIC. These bias voltages are also factory-tuned. If these transistors are replaced, the bias
voltage must be tuned using the Tuner software. Care must be taken not to damage the device by
exceeding the maximum allowed bias current. The device’s drain current is drawn directly from the
radio’s DC supply voltage input, PASUPVLTG, via current-measurement resistor R1409.
A matching network combines the output of the two devices and provides a 50-ohm source for the
antenna switch and harmonic filter.

3.4

Antenna Switch
The antenna switch is operated by the 9T1 voltage source which forward biases diodes D1401 and
D1402 during transmit, causing them to appear as low impedance. D1401 allows the RF output from
final stages Q1402 and Q1403 to be applied to the input of the low-pass harmonic filter (L1421-3
and associated components). D1402 appears as a short circuit at the input of the receiver (RXINJ),
preventing transmitter RF power from entering the receiver. L1420 and C1456 appear as a
broadband-wave transmission line, making the short circuit presented by D1402 appear as an open
circuit at the junction of D1401 and the harmonic filter input.
During receive mode, the 9T1 voltage is not present, and D1401 and D1402 do not conduct and
appear as open circuits. This allows signals from the antenna jack to pass to the receiver input, and
disconnects the transmitter final stages from this path.

3.5

Harmonic Filter
Components L1421- L1423 and C1449-C1455 form a seven-pole elliptic low-pass filter to attenuate
harmonic energy of the transmitter to specifications level. R1411 is used to drain electrostatic
charge that might otherwise build up on the antenna. The harmonic filter also prevents high level RF
signals above the receiver passband from reaching the receiver circuits, improving spurious
response rejection.

6881091C63-A

Chapter 7: 2-6

3.6

Low Band Transmitter Power Amplifier (PA) 60W

Power Control
The transmitter uses the Power Control IC (PCIC, U1503) to control the power output of the radio. A
differential DC amplifier U1502-1 compares the voltage drop across current-measuring resistor
R1409, which is proportional to the transmitter final stage DC current, with the voltage drop across
resistors R1508 and R1535, which is proportional to the current through transistor Q1503. This
transistor is controlled by the output of the differential amplifier, which varies the transistor current
until equilibrium of the two compared voltages is reached. The current through Q1503 develops a
voltage across R1513 which is exactly proportional to the DC current of the final stages. This voltage
is applied to the RF IN port of the PCIC (pin 1).
The PCIC has internal digital-to-analog converters (DACs) which provide a reference voltage of the
control loop. The reference voltage level is programmable through the SPI line of the PCIC. This
reference voltage is proportional to the desired power setting of the transmitter, and is factory
programmed at several points across the frequency range of the transmitter to offset frequency
response variations of the transmitter’s power detector circuitry.
The PCIC provides a DC output voltage at pin 4 (INT) which is amplified and shifted in DC level by
stages Q1504 and Q1505. The 0 to 4 volt DC range at pin 4 of U1503 is transferred to a 0 to 8 volt
DC range at the output of Q1505, and applied as VCNTRL to the power-adjust input pin of the first
transmitter stage U1401. This adjusts the transmitter power output to the intended value. Variations
in antenna impedance cause variations in the DC current of the final stages, and the PCIC adjust
the control voltage above or below its normal value to reduce power if current drain increases, or
raise power if current drain decreases.
Capacitors C1503-4 and C1525, in conjunction with resistors and integrators within the PCIC,
control the transmitter power-rise (key-up) and power-decay (de-key) characteristic to minimize
splatter into adjacent channels.
U1501 is a temperature-sensing device which monitors the circuit board temperature in the vicinity
of the transmitter circuits and provides a DC voltage to the PCIC (TEMP, pin 30) proportional to
temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter
output power will be reduced so as to reduce the transmitter temperature.

3.7

TX Safety Switch
The TX Safety Switch consists of S1501, Q1506, and diode pairs D1502 and D1503 providing
protection to the final stage devices Q1402 and Q1403. These final stage devices can be degraded
or destroyed if the radio is keyed without the cover in place due to the lack of a good thermal path to
the chassis.
Switch S1501 is closed when the radio’s cover is screwed in place by means of the carbonized
region on the cover’s pressure pad making contact with the finger plating on the radio’s PCB. With
the cover in place, transistor Q1506 is off, back-biasing diodes D1502 and D1503, enabling proper
transmitter operation. When the cover is not in place, S1501 opens, causing Q1506 to turn on,
pulling the cathodes of D1502 and D1503 to ground, resulting in the shorting of the transmitter’s
bias lines and control voltage.

Fractional-N Synthesizer
The LVFRAC-N synthesizer IC (U1201) consists of a reference oscillator, pre-scaler, a
programmable loop divider, control divider logic, phase detector, a charge pump, A/D converter for
low frequency digital modulation, a balance attenuator to balance high frequency analog modulation
and low frequency digital modulation, a 13V positive voltage multiplier, a serial interface for control,
and finally a super filter for the regulated 9.3 volt supply.
Regulated 9.3 volts DC applied to the super filter input (U1201, pin 30) delivers a very low noise
output voltage of 8.3 volts DC (VSF) at pin 28. External device Q1201 allows greater current
sourcing capability. The VSF source supplies the receive and transmit VCOs and first buffer stages.
The synthesizer IC supply voltage is provided by a dedicated 5V regulator (U1250) to minimize
power supply noise.
In order to generate a high voltage to supply the phase detector (charge pump) output stage at pin
VCP (U1201 pin 47), a capacitive voltage multiplier circuit (CR1202 and C1209) generates a voltage

6881091C63-A

Chapter 7: 2-8

Low Band Frequency Synthesis

of 13 volts DC. This multiplier is driven by two 1.05 MHz clock signals from U1201 pins 15 and 14
(VMULTI1 and VMULTI2) which are 180 degrees out of phase.
Output LOCK (U1201-4) provides information about the lock status of the synthesizer loop. A high
level at this output indicates a stable loop. A buffered output of the 16.8 MHz reference frequency is
provided at pin 19.
The operating frequency of the synthesizer is loaded serially from the µP via the data line (DATA,
U1201-7), clock line (CLK, U1201-8) and chip select line (CSX, U1201-9).
The reference oscillator circuit within U1201 uses an external 16.8 MHz crystal (Y1201). Varactor
CR1201 allows software-controlled frequency adjustments (warp) and temperature compensation of
the oscillator frequency. Warp adjustment is performed using serial data from the µP. This controls
the setting of an A/D converter, with its output (WARP, pin 25) applied to CR1201.

4.2

Voltage Controlled Oscillator (VCO) and Buffers
Separate voltage controlled oscillator (VCO) and buffer circuits, shown in Figure 7-4, are used for
receiver injection and transmitter carrier frequency generation. Since the receiver uses high-side
injection, the receiver VCO frequency range is 10.7 MHz above the transmit VCO range. The VCO/
buffers are bandsplit into three ranges depending on radio model, covering radio operating
frequencies of 29.7 to 36.0 MHz, 36.0 to 42.0 MHz, or 42.0 to 50.0 MHz. The corresponding three
frequency ranges from the receive VCO are 40.4 to 46.7 MHz, 46.7 to 52.7 MHz, and 52.7 to 60.7
MHz.

Chapter 7: 2-9

The VCOs, together with Fractional-N synthesizer U1201, generates the required frequencies for
transmit and receive modes. The TRB line (U1201, pin 2) determines which VCO/buffer circuit is to
be enabled. A high level on TRB will turn on the transistors in U1378 to turn on via R1376, applying
the 8.3 volt VSF source to the receiver VCO and first buffer. The second buffer in each string
operates from the 9.3V source and become active when RF is applied to their inputs.
The RF signal at the bases of the second buffers are combined and fed back to the Fractional-N
synthesizer via PRE_IN where it is compared to the reference frequency as described below in
Section 4.3. The Fractional-N IC provides a DC steering voltage VCTRL to adjust and maintain the
VCO at the correct frequency.
With a steering voltage from 2.5V to 11V at the appropriate varactor diode (CR1302 for the RX VCO,
or CR1310 for the TX VCO), the full VCO tuning range is obtained. Each VCO uses an AGC circuit
to maintain a constant VCO output level across the frequency band. A diode (CR1306 in the receive
VCO, or CR1314 in the transmit VCO) is configured as a voltage doubler which rectifies the RF level
sampled at the VCO drain and applies a proportional negative DC voltage to the VCO gate.
Increased RF level reduces the VCO gain to compensate.
The VCO output is taken from the source and applied to the first buffer transistor (Q1304 receive,
Q1307 transmit). The first buffer output is further amplified by the second buffer transistor (Q1305
receive, Q1308 transmit) before being applied to the receiver first mixer or transmitter first stage
input.
In TX mode the modulation signal coming from the LVFRAC-N synthesizer IC (MODOUT, U1201 pin
41) is superimposed on the DC steering line voltage by capacitive divider C1215, C1208 and
C1212, causing modulation of the TX VCO using the same varactor as used for frequency control.

4.3

Synthesizer Operation
The complete synthesizer subsystem comprises mainly a low voltage LVFRAC-N synthesizer IC,
Reference Oscillator (crystal oscillator with temperature compensation), charge pump circuitry, loop
filter circuitry, and voltage controlled oscillators and buffers. A sample of the VCO operating signal
PRE_IN is amplified by feedback buffer Q1202, low-pass filtered by L1205, C1222 and C1224, and
fed to U1201 pin 32 (PREIN).
The pre-scaler in the synthesizer (U1201) is basically a dual modulus pre-scaler with selectable
divider ratios. The divider ratio of the pre-scaler is controlled by the loop divider, which in turn
receives its inputs via the serial interface to the µP. The output of the pre-scaler is applied to the loop
divider. The output of the loop divider is connected to the phase detector, which compares the loop
divider’s output signal with the reference signal. The reference signal is generated by dividing down
the signal of the reference oscillator, whose frequency is controlled by Y1201.
The output signal of the phase detector is a pulsed DC signal which is routed to the charge pump.
The charge pump outputs a current at pin 43 of U1201 (IOUT). The loop filter (consisting of R12056, R1208, and C1212-14) transforms this current into a voltage that is applied to varactor diodes
(CR1310 for transmit, CR1302, for receive) and alters the output frequency of the appropriate VCO.
The current can be set to a value fixed in the LVFRAC-N IC or to a value determined by the currents
flowing into BIAS 1 (U1201-40) or BIAS 2 (U1201-39). The currents are set by the value of R1211 or
R1207 respectively. The selection of the three different bias sources is done by software
programming.
To reduce synthesizer lock time when new frequency data has been loaded into the synthesizer the
magnitude of the loop current is increased by enabling the IADAPT (U1201-45) for a certain

6881091C63-A

Chapter 7: 2-10

Low Band Frequency Synthesis

software programmable time (Adapt Mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range, the current is determined
only by the resistors connected to BIAS 1, BIAS 2, or the internal current source. A settled
synthesizer loop is indicated by a high level of signal LOCK (U1201-4).
In order to modulate the PLL the two-spot modulation method is utilized. Via pin 10 (MODIN) on
U1201, the audio signal is applied to both the A/D converter (low frequency path) and the balanced
attenuator (high frequency path). The A/D converter converts the low frequency analog modulating
signal into a digital code that is applied to the loop divider, thereby causing the carrier to deviate.
The balance attenuator is used to adjust the VCO’s deviation sensitivity to high frequency
modulating signals. The output of the balance attenuator is present at the MODOUT port (U120141) and superimposed on the VCO steering line voltage by a divider consisting of C1215, C1208
and C1212.

* Motorola Depot Servicing only
Reference designators with an asterisk indicate
components which are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.
†

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Section 1. Boards are not
orderable using the 84-prefixed number.

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Section 1. Boards are not
orderable using the 84-prefixed number.

* Motorola Depot Servicing only
Reference designators with an asterisk indicate
components which are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.

Reference designators with an asterisk indicate
components which are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.
†

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Section 1. Boards are not
orderable using the 84-prefixed number.

Introduction
This chapter provides a detailed theory of operation for the VHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

VHF (136-174 MHz) 25-45W Bipolar Receiver Front-End

2.1

Receiver Front-End
The receiver is able to cover the VHF range from 136 to 174 MHz. It consists of four major blocks:
front-end bandpass filters and pre-amplifier, first mixer, 1st IF, 2nd IF, and receiver back-end. Two
varactor-tuned bandpass filters perform antenna signal pre-selection. A passive double-balanced
mixer converts the signal to the first IF of 44.85 MHz. High-side injection is used.

VHF (136-174 MHz) 25-45W Bipolar Receiver Front-End

There are two 2-pole 44.85 MHz crystal filters in the 1st IF section and 2 pairs of 455 kHz ceramic
filters in the 2nd IF section to provide the required adjacent channel selectivity. The correct pair of
ceramic filters for 12.5 or 25kHz channel spacing is selected via control line BWSELECT. The
second IF at 455 kHz is mixed, amplified and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuits, before being applied to the
receiver pre-selector filter (C3001, C3002, D3001 and associated components). The 2-pole preselector filter tuned by the dual varactor diode D3001 pre-selects the incoming signal (RXIN) from
the antenna switch to reduce spurious effects to following stages. The tuning voltage (FECTRL_1)
ranging from 2 volts to 8 volts is controlled by pin 20 of PCIC (U3501) in the Transmitter section. A
dual hot carrier diode (D3003) limits any inband signal to 0 dBm to prevent damage to the preamplifier.
The RF pre-amplifier is a surface mount device (SMD) Q3001 with collector-base feedback to
stabilize gain, impedance, and intermodulation. Transistor Q3002 compares the voltage drop across
resistor R3002 with a fixed base voltage from divider R3011, R3000 and R3012, and adjusts the
base current of Q3001 as necessary to maintain its collector current constant at approximately 1520 mA. Operating voltage is from the regulated 9.3V supply (9V3). During transmit, 9.1 volts (K9V1)
turns off both transistors Q3002 and Q3001. This protects the RF pre-amplifier from excessive
dissipation during transmit mode. A following 3dB pad (R3006 – R3008 and R3016 – R3018)
stabilizes the output impedance and intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
The dual varactor diode D3004 is controlled by the same signal FECTRL_1, which controls the preselector filter.

2.3

First Mixer and 1st Intermediate Frequency (IF)
The signal coming from the front-end is converted to the 1st IF frequency of 44.85 MHz using a
passive double-balanced mixer (D3031). Its ports are matched for incoming RF signal conversion to
the 44.85 MHz IF using high side injection. The high-side injection signal (RXINJ) from the
frequency synthesizer circuit has a level of approximately +13 dBm and is injected via matching
transformer T3002.
The IF output signal (IF) from transformer T3001 pin 2 is fed to the first 2-pole crystal filter FL3101.
The filter output in turn is matched to IF amplifier Q3101 which is actively biased by a collector base
feedback (R3101, R3106) to a current drain of approximately 5 mA drawn from the 5 volt supply. Its
output impedance is matched to the second 2-pole crystal filter FL3102. The signal is further
amplified by a pre-amplifier (Q3102) before going into pin 1 of IFIC (U3101).
A dual hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

2.4

2nd Intermediate Frequency (IF) and Receiver Back-End
The 44.85 MHz 1st IF signal from the second IF amplifier feeds the IF IC (U3101) at pin1. Within the
IF IC, the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator (2nd LO) to
produce the 2nd IF signal at 455 kHz. The 2nd LO frequency is determined by crystal Y3101. The
2nd IF signal is amplified and filtered by an external pair of 455 kHz ceramic filters FL3112, FL3114
for 20/25 kHz channel spacing or FL3111, FL3113/F3115 for 12.5 kHz channel spacing. These pairs

6881091C63-A

VHF (136-174 MHz) 25-45W Bipolar Transmitter Power Amplifier (PA) 45W

Chapter 8: 2-3

are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the limiter
input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U3101 pin 8 (DISCAUDIO) which is fed to the ASFIC_CMP (U0221) pin 2 (part of
the Controller circuits).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101, pin 5, having a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101, pin 63) and in addition is available
at accessory connector J0501-15.

3.0

VHF (136-174 MHz) 25-45W Bipolar Transmitter Power Amplifier
(PA) 45W
The radio’s 45W PA is a four-stage amplifier used to amplify the output from the VCOBIC to the
radio transmit level. The line-up consists of three stages which utilize LDMOS technology, followed
by a final stage using a bipolar device. The gain of the first stage (U3401) is adjustable, controlled by
pin 4 of PCIC (U3501) via Q3501 and Q3502 (VCONT). It is followed by an LDMOS pre-driver stage
(Q3421), an LDMOS driver stage (Q3431) and a bipolar final stage (Q3441).

Devices U3401 and Q3421 are surface mounted. The remaining devices are directly attached to the
heat sink.

3.1

Power Controlled Stage
The first stage (U3401) is a 20 dB gain integrated circuit containing two LDMOS FET amplifier
stages. It amplifies the RF signal from the VCO (TXINJ). The output power of stage U3401 is
controlled by a DC voltage applied to pin 1 from the power control circuit (U3501 pin 4, with
transistors Q3501 and Q3502 providing current gain and level-shifting). The control voltage
6881091C63-A

Chapter 8: 2-4

VHF (136-174 MHz) 25-45W Bipolar Transmitter Power Amplifier (PA) 45W

simultaneously varies the bias of two FET stages within U3401. This biasing point determines the
overall gain of U3401 and therefore its output drive level to Q3421, which in turn controls the output
power of the PA.
In receive mode the voltage control line is at ground level and turns off Q3501-2, which in turn
switches off the biasing voltage to U3401.

3.2

Pre-Driver Stage
The next stage is an LDMOS device (Q3421) providing a gain of +13 dB. This device requires a
positive gate bias and a quiescent current flow for proper operation. The voltage of the line
PCIC_MOSBIAS_1 is set during transmit mode by the PCIC pin 24, and fed to the gate of Q3421 via
the resistive network R3410, R3415, and R3416. The bias voltage is factory tuned.

3.3

Driver Stage
The following stage is an enhancement-mode N-Channel MOSFET device (Q3431) providing a gain
of 10 dB. This device also requires a positive gate bias and a quiescent current flow for proper
operation. The voltage of the line MOSBIAS_2 is set in transmit mode by the ASFIC and fed to the
gate of Q3431 via the resistive network R3404, R3406, and R3431-5. This bias voltage is also tuned
in the factory. If the transistor is replaced, the bias voltage must be tuned using the Customer
Programming Software (CPS). Care must be taken not to damage the device by exceeding the
maximum allowed bias voltage. The device’s drain current is drawn directly from the radio’s DC
supply voltage input, PASUPVLTG, via L3431 and L3432.

3.4

Final Stage
The final stage uses bipolar device Q3441. The device’s collector current is also drawn from the
radio’s DC supply voltage input. To maintain class C operation, the base is DC-grounded by a series
inductor (L3441) and a bead (L3442). A matching network consisting of C3446-52, C3467, L34445, and two striplines, transforms the impedance to approximately 50 ohms and feeds the directional
coupler.

3.5

Directional Coupler
The directional coupler is a microstrip printed circuit, which couples a small amount of the forward
and reflected power delivered by Q3441. The coupled signals are rectified by D3451-2 and
combined by R3463-4. The resulting DC voltage is proportional to RF output power and feeds the
RFIN port of the PCIC (U3501, pin 1). The PCIC controls the gain of stage U3401 as necessary to
hold this voltage constant, thus ensuring the forward power out of the radio to be held to a constant
value.
An abnormally high reflected power level, such as may be caused by a damaged antenna, also
causes the DC voltage applied to the PCIC to increase, and this will cause a reduction in the gain of
U3401, reducing transmitter output power to prevent damage to the final device due to an improper
load.

3.6

Antenna Switch
The antenna switch consists of two PIN diodes, D3471 and D3472. In the receive mode, both diodes
are off. Signals applied at the antenna jack J3401 are routed, via the harmonic filter, through
network L3472, C3474 and C3475, to the receiver input. In the transmit mode, the keyed 9 volts
turns on Q3471 which enables current sink Q3472, set to 96 mA by R3473 and VR3471. This
completes a DC path from PASUPVLTG, through L3473, D3471, L3477, L3472, D3472, L3471,

6881091C63-A

VHF (136-174 MHz) 25-45W Bipolar Frequency Synthesis

Chapter 8: 2-5

R3474 and the current sink, to ground. Both diodes are forward biased into conduction. The
transmitter RF from the directional coupler is routed via D3471 to the harmonic filter and antenna
jack. D3472 also conducts, shunting RF power and preventing it from reaching the receiver port
(RXIN). L3472 is selected to appear as a broadband quarter-wave transmission line, making the
short circuit presented by D3472 appear as an open circuit at the junction of D3472 and the receiver
path.

3.7

Harmonic Filter
Components L3491-L3494 and C3490-C3498 form a nine-pole Chebychev low-pass filter to
attenuate harmonic energy of the transmitter. R3490 is used to drain electrostatic charge that might
otherwise build up on the antenna. The harmonic filter also prevents high level RF signals above the
receiver passband from reaching the receiver circuits, improving spurious response rejection.

3.8

Power Control
The transmitter uses the power control IC (PCIC, U3501) to control the power output of the radio. A
portion of the forward and reflected RF power from the transmitter is sampled by the directional
coupler, rectified and summed, to provide a DC voltage to the RFIN port of the PCIC (pin 1) which is
proportional to the sampled RF power.
The ASFIC contains a digital-to-analog converter (DAC) which provides a reference voltage of the
control loop to the PCIC via R3517. The reference voltage level is programmable through the SPI
line of the PCIC. This reference voltage is proportional to the desired power setting of the
transmitter, and is factory programmed at several points across the frequency range of the
transmitter to offset frequency response variations of the transmitter’s power detector circuit.
The PCIC provides a DC output voltage at pin 4 (INT) which is amplified and shifted in DC level by
stages Q3501 and Q3502. The 0 to 4 VDC range at U1503, pin 4 is translated to a 0 to 8.5 VDC
range at the output of Q3501, and applied as VCONT to the power-adjust input pin of the first
transmitter stage U3401. This adjusts the transmitter power output to the intended value. Variations
in forward or reflected transmitter power cause the DC voltage at pin 1 to change, and the PCIC
adjusts the control voltage above or below its nominal value to raise or lower output power.
Capacitors C3502-4, in conjunction with resistors and integrators within the PCIC, control the
transmitter power-rise (key-up) and power-decay (de-key) characteristic to minimize splatter into
adjacent channels.
U3502 is a temperature-sensing device, which monitors the circuit board temperature in the vicinity
of the transmitter driver and final devices, and provides a DC voltage to the PCIC (TEMP, pin 29)
proportional to temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the
transmitter output power is reduced so as to reduce the transmitter temperature.

controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U3201 (pin 25)
to set the frequency of the oscillator. The output of the oscillator (U3262 pin 3) is applied to pin 23
(XTAL1) of U3201 via R3263 and C3235.
In applications where less frequency stability is required, the oscillator inside U3201 is used along
with an external crystal Y3261, varactor diode D3261, C3261, C3262 and R3262. In this case,
Y3262, R3263, C3235 and C3251 are not used. When Y3262 is used, Y3261, D3261, C3261,
C3262 and R3262 are not used, and C3263 is increased to 0.1 uF.

control divider logic, a phase detector, a charge pump, an A/D converter for low frequency digital
modulation, a balance attenuator to balance high frequency analog modulation and low frequency
digital modulation, a 13 volt positive voltage multiplier, a serial interface for control, and finally a
super filter for the regulated 5 volts.

A voltage of 5V applied to the super filter input (U3201 pin 30) supplies an output voltage of 4.5 VDC
(VSF) at pin 28. It supplies the VCO, VCO modulation bias circuit (via R3363) and the synthesizer
charge pump resistor network (R3251, R3252). The synthesizer supply voltage is provided by the
5V regulator U3211.
In order to generate a high voltage to supply the phase detector (charge pump) output stage at pin
VCP (U3201-47), a voltage of 13 VDC is being generated by the positive voltage multiplier circuits
(D3201, C3202, C3203). This voltage multiplier is basically a diode capacitor network driven by two
signals (1.05MHz) 180 degrees out of phase signals (U3201-14 and -15).

The VCOBIC together with the Fractional-N synthesizer (U3201) generates the required frequencies
in both the transmit and receive modes. The TRB line (U3301, pin 19) determines which tank circuits
and internal buffers are to be enabled. A high level on TRB enables the TX tank and TX output (pin
10), and a low enables the RX tank and RX output (pin 8). A sample of the signal from the enabled
RF output is routed from U3301, pin 12 (PRESC_OUT), via a low-pass filter, to U3201, pin 32
(PREIN).

6881091C63-A

Chapter 8: 2-8

VHF (136-174 MHz) 25-45W Bipolar Frequency Synthesis

A steering line voltage (VCTRL) between 2.5 volts and 11 volts at varactor diode D3361 tune the full
TX frequency range (TXINJ) from 136 MHz to 174 MHz, and varactor diode D3341 tunes the full RX
frequency range (RXINJ) from 181 MHz to 219 MHz. The RX tank circuit uses a Hartley
configuration for wider bandwidth. For the RX tank circuit, an external transistor Q3304 is used for
better side-band noise.
The external RX buffers (Q3301 and Q3302) are enabled by a high at U3301, pin 7 (RX_SWITCH)
via transistor switch Q3303. In the TX mode, the modulation signal (VCOMOD) from the LVFRAC-N
synthesizer IC (U3201 pin 41) is applied to varactor diode D3362, which modulates the TX VCO
frequency via capacitor C3362. Varactor D3362 is biased for linearity from the VSF.

4.4

Synthesizer Operation
The complete synthesizer subsystem consists of the low voltage FRAC-N (LVFRACN), reference
oscillator (a crystal oscillator with temperature compensation), charge pump circuit, loop filter circuit
and a DC supply. The output signal PRESC from the VCOBIC (U3301 pin 12) is fed to U3201 pin 32
(PREIN) via a low-pass filter (C3318, L3318 and C3226) which attenuates harmonics and provides
the correct level to close the synthesizer loop.
The pre-scaler in the synthesizer (U3201) is a dual modulus type with selectable divider ratios. The
divider ratio of the pre-scaler is controlled by the loop divider, which in turn receives its inputs via the
SRL. The output of the pre-scaler is applied to the loop divider. The output of the loop divider is
connected to the phase detector, which compares the loop divider’s output signal with the reference
signal. The reference signal is generated by dividing down the signal of reference oscillator Y3261
or Y3262.
The output signal of the phase detector is a pulsed DC signal which is routed to the charge pump.
The charge pump outputs a current at U3201 pin 43 (IOUT). The loop filter (which consists of
R3221-R3223 and C3221-C3224) transforms this current into a voltage that is applied to the
varactor diodes (D3361 for transmit, D3341 for receive) to alter the output frequency of the
appropriate VCO. The current can be set to a value fixed within the LVFRAC-N IC, or to a value
determined by the currents flowing into BIAS 1 (U3201-40) or BIAS 2 (U3201-39). The currents are
set by the value of R3251 and R3252 respectively. The selection of the three different bias sources
is done by software programming.
To reduce synthesizer lock time when new frequency data has been loaded into the synthesizer, the
magnitude of the loop current is increased by enabling the IADAPT pin (U3201-45) for a certain
software programmable time (adapt mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range, the current is determined
only by the resistors connected to BIAS 1 and BIAS 2, or by the internal current source. A settled
synthesizer loop is indicated by a high level signal at U3201-4 (LOCK).
The LOCK signal is routed to one of the µP’s ADC inputs (U0101-56). From the measured voltage,
the µP determines whether LOCK is active.
To modulate the PLL, the two spot modulation method is utilized. Via U3201, pin 10 (MODIN), the
audio signal is applied to both the A/D converter (low frequency path) as well as the balance
attenuator (high frequency path). The A/D converter changes the low frequency analog modulating
signal into a digital code that is applied to the loop divider, thereby causing the carrier to deviate.
The balance attenuator is used to adjust the VCO’s deviation sensitivity to high frequency
modulating signals. The output of the balance attenuator is present at the MODOUT port (U320141) and connected to the VCO modulation diode D3362 via R3364.

* Motorola Depot Servicing only
Reference designators with an asterisk indicate
components which are not field-replaceable
because they need to be calibrated with
specialized factory equipment after installation.
Radios in which these parts have been replaced in
the field will be off frequency at temperature
extremes.

†

Replacement boards must be ordered from
CCSD (formerly AAD) using the number shown
in the model charts in Section 1. Boards are not
orderable using the 84-prefixed number.

Introduction
This chapter provides a detailed theory of operation for the UHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

UHF Band 1 (403-470 MHz) 25-40W Bipolar Receiver Front-End

2.1

Receiver Front-End
The receiver is able to cover the UHF range from 403 to 470 MHz. It consists of four major blocks:
front-end bandpass filters and pre-amplifier, first mixer, 1st IF, 2nd IF and receiver back-end. Two
varactor tuned bandpass filters perform antenna signal pre-selection. A passive double-balanced
mixer converts the signal to the 1st IF of 44.85 MHz. Low side first injection is used.

UHF Band 1 (403-470 MHz) 25-40W Bipolar Receiver Front-End

The 2-pole 44.85 MHz crystal filters in the 1st IF section and two pairs of 455 kHz ceramic filters in
the 2nd IF section provide the required adjacent channel selectivity. The correct pair of ceramic
filters for 12.5 or 25 kHz channel spacing is selected via control line BWSELECT. The 2nd IF at 455
kHz is mixed, amplified, and demodulated in the IF IC. The processing of the demodulated audio
signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuits, before being applied to the
receiver pre-selector filter (C4001, C4002, D4001 and associated components). The 2-pole preselector filter tuned by the varactor diodes D4001 and D4002 pre-selects the incoming signal (RXIN)
from the antenna switch to reduce spurious effects to following stages. The tuning voltage
(FECTRL_1) ranging from 2 volts to 8 volts is controlled by pin 20 of PCIC (U4501) in the
Transmitter section. A dual hot carrier diode (D4003) limits any inband signal to 0 dBm to prevent
damage to the pre-amplifier.
The RF pre-amplifier is an SMD device (Q4003) with collector base feedback to stabilize gain,
impedance, and intermodulation. The collector current of approximately 11-16 mA is drawn from the
9.3 volt supply via L4003 and R4002. A 3dB pad (R4006, R4007, R4011 and R4008 - R4010)
stabilizes the output impedance and intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
The varactor diodes D4004 and D4005 are controlled by the same signal FECTRL_1, which
controls the pre-selector filter. A following 1 dB pad (R4013 - R4015) stabilizes the output
impedance and intermodulation performance.

2.3

First Mixer and 1st Intermediate Frequency (IF)
The signal coming from the front-end is converted to the first IF (44.85 MHz) using a passive doublebalanced mixer (D4051). Its ports are matched for incoming RF signal conversion to the 44.85 MHz
IF using low side injection via matching transformers T4051 and T4052. The injection signal (RXINJ)
coming from the RX VCO buffer (Q4332) is filtered by the low-pass filter consisting of (L4053,
L4054, C4053 - C4055) followed by a matching transformer T4052 and has a level of approximately
15dBm.
The mixer IF output signal (IF) from transformer T4501pin 2 is fed to the first two pole crystal filter
FL3101. The filter output in turn is matched to the following IF amplifier.
The IF amplifier Q3101 is actively biased by a collector base feedback (R3101, R3106) to a current
drain of approximately 5 mA drawn from the 5 volt supply. Its output impedance is matched to the
second two pole crystal filter FL3102. The signal is further amplified by a pre-amplifier (Q3102)
before going into pin 1 of IFIC (U3101).
A dual hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

2.4

2nd Intermediate Frequency (IF) and Receiver Back-End
The 44.85 MHz 1st IF signal from the second IF amplifier feeds the IF IC (U3101) at pin1. Within the
IF IC the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator (2nd LO) to
produce the low IF signal at 455 kHz. The 2nd LO frequency is determined by crystal Y3101. The

6881091C63-A

UHF Band 1 (403-470 MHz) 25-40W Bipolar Transmitter Power Amplifier (PA) 40W

Chapter 9: 2-3

2nd IF signal is amplified and filtered by an external pair of 455 kHz ceramic filters (FL3112, FL3114)
for 20/25 kHz channel spacing or FL3111 and FL3113/F3115 for 12.5 kHz channel spacing. These
pairs are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the
limiter input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U3103 pin 8 (DISCAUDIO) which is fed to the ASFIC_CMP (U0221) pin 2 (part of
the controller circuits).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101 pin 5, having a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101 pin 63) and is available at
accessory connector J0501-15.

3.0

UHF Band 1 (403-470 MHz) 25-40W Bipolar Transmitter Power
Amplifier (PA) 40W
The radio’s 40W power amplifier (PA) is a four-stage amplifier used to amplify the output from the
VCOBIC to the radio transmit level. It consists of the following four stages in the line-up. The first
stage is a LDMOS pre-driver (U4401) that is controlled by pin 4 of PCIC (U4501) via Q4473
(CNTLVLTG). It is followed by another LDMOS stage (Q4421), an LDMOS stage (Q4431), and a
bipolar final stage (Q4441).

3.1

Power Controlled Stage
The first stage (U4401) amplifies the RF signal from the VCO (TXINJ) and controls the output power
of the PA. The output power of the transistor U4401 is controlled by a voltage control line feed from

6881091C63-A

Chapter 9: 2-4

UHF Band 1 (403-470 MHz) 25-40W Bipolar Transmitter Power Amplifier (PA) 40W

the PCIC pin4(U4501). The control voltage simultaneously varies the bias of two FET stages within
U4401. This biasing point determines the overall gain of U4401 and therefore its output drive level to
Q4421, which in turn controls the output power of the PA.
In receive mode the voltage control line is at ground level and turns off Q4473 which in turn switches
off the biasing voltage to U4401.

3.2

Pre-Driver Stage
The next stage is a 13dB gain LDMOS device (Q4421) which requires a positive gate bias and a
quiescent current flow for proper operation. The voltage of the line PCIC_MOSBIAS_1 is set in
transmit mode by PCIC pin 24 and fed to the gate of Q4421 via the resistive network R4407, R4408,
R4416 and R4415. The bias voltage is tuned in the factory.

3.3

Driver Stage
The following stage is an enhancement-mode N-Channel MOSFET device (Q4431) providing a gain
of 10dB. This device also requires a positive gate bias and a quiescent current flow for proper
operation. The voltage of the line Bias_2_UHF_PA_1 is set in transmit mode by the ASFIC and fed
to the gate of Q4431 via the resistive network R4630, R4631, and R4632. This bias voltage is also
tuned in the factory. If the transistor is replaced, the bias voltage must be tuned using the Customer
Programming Software (CPS). Care must be taken not to damage the device by exceeding the
maximum allowed bias voltage. The device’s drain current is drawn directly from the radio’s DC
supply voltage input, A+, via L4421.

3.4

Final Stage
The final stage uses the bipolar device Q4441. The device’s collector current is also drawn from the
radio’s DC supply voltage input. To maintain class C operation, the base is DC-grounded by a series
inductor (L4441) and a bead (L4440). A matching network consisting of C5541-C5544 and two
striplines transform the impedance to 50 Ohms and feeds the directional coupler.

3.5

Bi-directional Coupler
The bi-directional coupler is a microstrip printed circuit, which couples a small amount of the forward
and reverse power of the RF power from Q4441. The coupled signal is rectified to an output power
proportional DC voltage by the diodes D4451 & D4452 and sent to the RFIN of the PCIC. The PCIC
controls the gain of stage U4401 as necessary to hold this voltage constant. This ensures the
forward power out of the radio is held to a constant value.

3.6

Antenna Switch
The antenna switch utilizes the existing DC feed (A+) to the last stage device (Q4441). Basic
operation is to have both PIN diodes D4471 and D4472 turns on during key-up by forward biasing
them. It is achieve by pulling down the voltage at the cathode end of D4472 to around 11.8V (0.7V
drop across each diode). The current through the diodes needs to be set around 80mA to fully open
the transmit path through resistor R4496. Q4472 is a current source controlled by Q4471 and is
eventually connected to pin ANO of PCIC. VR4471 ensures the voltage at the resistor R4511 never
exceeds 5.6V.

Chapter 9: 2-5

Harmonic Filter
Inductors L4491, L4492, L4493 and capacitors C4448, C4493,C4494, C4496 and C4498 form a
low-pass filter to attenuate harmonic energy from the transmitter. R4491 is used to drain any
electrostatic charges that might otherwise build up on the antenna. The harmonic filter also prevents
high level RF signals above the receiver passband from reaching the receiver circuits, improving
spurious response rejection.

3.8

Power Control
The transmitter uses the Power Control IC (PCIC, U4501) to control the power output of the radio. A
portion of the forward RF power from the transmitter is sampled by the bi-directional coupler and
rectified, to provide a DC voltage to the RFIN port of the PCIC (pin 1) which is proportional to the
sampled RF power.
The PCIC has internal digital-to-analog converters (DACs) which provide the reference voltage of
the control loop. The reference voltage level is programmable through the SPI line of the PCIC. This
reference voltage is proportional to the desired power setting of the transmitter, and is factory
programmed at several points across the frequency range of the transmitter to offset frequency
response variations of the transmitter’s power detector circuits.
The PCIC provides a DC output voltage at pin 4 (INT) and applied as CNTLVLTG to the poweradjust input pin of the first transmitter stage U4401. This adjusts the transmitter power output to the
intended value. Variations in forward or reflected transmitter power cause the DC voltage at pin 1 to
change, and the PCIC adjusts the control voltage above or below its nominal value to raise or lower
output power.
Capacitors C4502-4, in conjunction with resistors and integrators within the PCIC, control the
transmitter power-rise (key-up) and power-decay (de-key) characteristic to minimize splatter into
adjacent channels.
U4502 is a temperature-sensing device, which monitors the circuit board temperature in the vicinity
of the transmitter driver and final devices, and provides a DC voltage to the PCIC (TEMP, pin 29)
proportional to temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the
transmitter output power is reduced so as to reduce the transmitter temperature.

4.0

UHF Band 1 (403-470 MHz) 25-40W Bipolar Frequency Synthesis
The synthesizer subsystem consists of the reference oscillator (Y4261 or Y4262), the low voltage
fractional-N synthesizer (LVFRAC-N, U4201), and the Voltage Controlled Oscillator VCO.

4.1

Reference Oscillator
The reference oscillator (Y4262) contains a temperature compensated crystal oscillator with a
frequency of 16.8 MHz. An analog-to-digital (A/D) converter internal to U4201 (LVFRAC-N) and
controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U4201, pin 25 to
set the frequency of the oscillator. The output of the oscillator (pin 3 of Y4262) is applied to pin 23
(XTAL1) of U4201 via an RC series combination.
In applications where less frequency stability is required the oscillator inside U4201 is used along
with an external crystal Y4261, varactor diode D4261, C4261, C4262 and R4262. In this case,

Y4262, R4263, C4235 and C4251 are not used. When Y4262 is used, Y4261, D4261, C4261,
C4262 and R4262 are not used, and C4263 is increased to 0.1 uF.

4.2

Fractional-N Synthesizer
The LVFRAC-N synthesizer IC (U4201) consists of a pre-scaler, a programmable loop divider,
control divider logic, a phase detector, a charge pump, an A/D converter for low frequency digital
modulation, a balanced attenuator to balance high frequency analog modulation and low frequency
digital modulation, a 13V positive voltage multiplier, a serial interface for control, and finally a super
filter for the regulated 5 volts.
A voltage of 5V applied to the super filter input (U4201 pin 30) supplies an output voltage of 4.5 Vdc
(VSF) at pin 28. It supplies the VCO, VCO modulation bias circuit (via R4322) and the synthesizer
charge pump resistor network (R4251, R4252). The synthesizer supply voltage is provided by the
5V regulator U4211.
In order to generate a high voltage to supply the phase detector (charge pump) output stage at pin
VCP (U5701-32), a voltage of 13 Vdc is being generated by the positive voltage multiplier circuitry
(D4201, C4202, C4203). This voltage multiplier is basically a diode capacitor network driven by two
signals (1.05MHz) 180 degrees out of phase (U4201-14 and -15).

Voltage Controlled Oscillator (VCO)
The Voltage Controlled Oscillator (VCO) consists of the VCO buffer IC (VCOBIC, U4301), the TX
and RX tank circuits, the external RX buffer stages, and the modulation circuits.
The VCOBIC together with Fractional-N synthesizer (U4201) generates the required frequencies in
both transmit and receive modes. The TRB line (U4301 pin 19) determines which tank circuits and
internal buffers are to be enabled. A high level on TRB enables TX tank and TX output (pin 10), and
a low enables RX tank and RX output (pin 8). A sample of the signal from the enabled output is
routed from U4301 pin 12 (PRESC_OUT), via a low-pass filter, to pin 32 of U4201 (PREIN).
A steering line voltage (VCTRL) between 3.0V and 10.0V at varactor diode CR4311 will tune the full
TX frequency range (TXINJ) from 403 MHz to 470 MHz, and at varactor diodes CR4301, CR4302
and CR4303 will tune the full RX frequency range (RXINJ) from 358 MHz to 425 MHz. The tank
circuits uses the Hartley configuration for wider bandwidth. For the RX tank circuit, an external
transistor Q4301 is used in conjunction with the internal transistor for better side-band noise.

pin41) is applied to the modulation circuits CR4321, R4321, R4322 and C4324. These modulate the
TX VCO frequency via coupling capacitor C4321. Varactor CR4321 is biased for linearity from the
VSF.

4.4

UHF Band 1 (403-470 MHz) 25-40W Bipolar Frequency Synthesis

Synthesizer Operation
The complete synthesizer subsystem comprises mainly of a low voltage FRAC-N (LVFRACN) IC,
Reference Oscillator (crystal oscillator with temperature compensation), charge pump circuits, loop
filter circuits, and DC supply. The output signal (PRESC_OUT) of the VCOBIC (U4301, pin12) is fed
to of U4201, pin 32 (PREIN) via a low-pass filter (C4229,L4225,C4226) which attenuates harmonics
and provides correct level to close the synthesizer loop.
The pre-scaler in the synthesizer (U4201) is basically a dual modulus pre-scaler with selectable
divider ratios. The divider ratio of the pre-scaler is controlled by the loop divider, which in turn
receives its inputs via the SRL. The output of the pre-scaler is applied to the loop divider. The output
of the loop divider is connected to the phase detector, which compares the loop divider’s output
signal with the reference signal. The reference signal is generated by dividing down the signal of the
reference oscillator (Y4261 or Y4262).
The output signal of the phase detector is a pulsed DC signal which is routed to the charge pump.
The charge pump outputs a current at pin 43 of U4201 (IOUT). The loop filter (which consists of
R4221-R4223, C4221-C4225,L4221) transforms this current into a voltage that is applied to the
varactor diodes CR4311 for transmit, CR4301, CR4302 & CR4303 for receive and alters the output
frequency of the VCO. The current can be set to a value fixed in the LVFRAC-N IC or to a value
determined by the currents flowing into BIAS 1 (U4201-40) or BIAS 2 (U4201-39). The currents are
set by the value of R4251 or R4252 respectively. The selection of the three different bias sources is
done by software programming.
To reduce synthesizer lock time when new frequency data has been loaded into the synthesizer the
magnitude of the loop current is increased by enabling the IADAPT (U4201-45) for a certain
software programmable time (Adapt Mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range the current is determined
only by the resistors connected to BIAS 1, BIAS 2, or the internal current source. A settled
synthesizer loop is indicated by a high level of signal LOCK (U4201-4).
LOCK (U4201-4) signal is routed to one of the µP’s ADCs input U101-56. From the voltage the µP
determines whether LOCK is active.
In order to modulate the PLL the two spot modulation method is utilized Via pin 10 (MODIN) on
U4201. The audio signal is applied to both the A/D converter (low frequency path) as well as the
balanced attenuator (high frequency path). The A/D converter converts the low frequency analog
modulating signal into a digital code which is applied to the loop divider, thereby causing the carrier
to deviate. The balance attenuator is used to adjust the VCO’s deviation sensitivity to high frequency
modulating signals. The output of the balance attenuator is present at the MODOUT port (U420141) and connected to the VCO modulation diode CR4321 via R4321, C4325.

Introduction
This chapter provides a detailed theory of operation for the UHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

UHF Band 2 (450-512/520 MHz) 25-40W Bipolar Receiver FrontEnd

2.1

Receiver Front-End
The UHF receiver, shown in Figure 10-1, is able to cover the UHF range from 450 to 512 MHz (for
CDM models) and from 450 to 520 MHz (for PRO models). It consists of four major blocks: front-end
bandpass filters and pre-amplifier, first mixer, high-IF, low-IF and receiver back-end. Two varactortuned bandpass filters perform antenna signal pre-selection. A passive double-balanced mixer
converts the signal to the first IF of 44.85 MHz. Low-side first injection is used.

Chapter 10: 2-2

UHF Band 2 (450-512/520 MHz) 25-40W Bipolar Receiver Front-End

The two 2-pole 44.85 MHz crystal filters in the high-IF section and two pairs of 455 kHz ceramic
filters in the low-IF section provide the required adjacent channel selectivity. The correct pair of
ceramic filters for 12.5 or 25 kHz channel spacing is selected via control line BWSELECT. The
second IF at 455 kHz is mixed, amplified, and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuits, before being applied to the
receiver pre-selector filter (C5001, C5002, D5001, and related components). The 2-pole preselector filter, tuned by the varactor diodes D5001 and D5002, pre-select the incoming signal (RXIN)
from the antenna switch to reduce spurious effects to the stages that follow. The tuning voltage
(FECTRL_1), ranging from 2 volts to 8 volts, is controlled by pin 20 of PCIC (U5501) in the
transmitter section. A dual hot carrier diode (D5003) limits any inband signal to 0 dBm to prevent
damage to the pre-amplifier.
The RF pre-amplifier is an SMD device (Q5003) with collector base feedback to stabilize gain,
impedance, and intermodulation. The collector current of approximately 11-16 mA is drawn from the
9.3 volt supply via L5003 and R5002. A 3dB pad (R5006, R5007, R5011, and R5008 - R5010)
stabilizes the output impedance and intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
Varactor diodes D5004 and D5005 are controlled by the same signal, FECTRL_1, which controls
the pre-selector filter. A following 1 dB pad (R5013 - R5015) stabilizes the output impedance and
intermodulation performance.

2.3

First Mixer and High Intermediate Frequency (IF)
The signal from the front-end is converted to the first IF (44.85 MHz) using passive double-balanced
mixer D5051. Its ports are matched for incoming RF signal conversion to the 44.85 MHz IF using low
side injection via matching transformers T5051 and T5052. The injection signal (RXINJ) coming
from the RX VCO buffer (Q5332) is filtered by the low-pass filter consisting of L5053, L5054, and
C5053 - C5055 followed by matching transformer T5052 which has a level of approximately 15dBm.
The mixer IF output signal from transformer T5501, pin 2 is fed to the first two-pole crystal filter
(FL3101). The filter output in turn is matched to IF amplifier Q3101 which is actively biased using
collector-base feedback resistors R3101and R3106 to provide a current drain of approximately 5
mA drawn from the 5 volt supply. The output impedance of this device is matched to the second twopole crystal filter FL3102. The signal is further amplified by a pre-amplifier Q3102 before going to pin
1 of IFIC (U3101).
A dual, hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

2.4

Low Intermediate Frequency (IF) and Receiver Back-End
The 44.85 MHz first IF signal from the second IF amplifier feeds the IF IC (U3101) at pin1. Within the
IF IC the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator to produce a
low IF signal of 455 kHz. The second LO frequency is determined by crystal Y3101. The second IF
signal is amplified and filtered by an external pair of 455 kHz ceramic filters (FL3112 and FL3114) for
20/25 kHz channel spacing, or FL3111 and FL3113/F3115 for 12.5 kHz channel spacing. These

pairs are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the
limiter input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U3103, pin 8 (DISCAUDIO) which is fed to ASFIC_CMP U0221, pin 2 (part of the
controller circuits).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101, pin 5, which has a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101, pin 63) and is available at
accessory connector J0501-15.

3.0

UHF Band 2 (450-512/520 MHz) 25-40W Bipolar Transmitter
Power Amplifier (PA) 40W
The radio’s 40W power amplifier (PA), shown in Figure 10-2, is a four-stage amplifier used to amplify
the output from the VCOBIC to the radio transmit level. The first stage is an LDMOS pre-driver
(U5401) controlled by pin 4 of PCIC (U5501) via Q5473 (CNTLVLTG). This stage is followed by
another LDMOS stage (Q5421), LDMOS stage Q5431, and a bipolar final stage (Q5441). Device
Q5401 is surface mounted and Q5421, Q5431, and Q5441 are directly attached to the heat sink.

3.1

Power Controlled Stage
The first stage (U5401) amplifies the RF signal from the VCO (TXINJ) and controls the output power
of the PA. The output power of the transistor U5401 is controlled by a voltage control line feed from
the PCIC (U5501, pin 4). The control voltage simultaneously varies the bias of two FET stages
within U5401. This biasing point determines the overall gain of U5401 and therefore its output drive
level to Q5421, which in turn controls the output power of the PA.

Chapter 10: 2-4

UHF Band 2 (450-512/520 MHz) 25-40W Bipolar Transmitter Power Amplifier (PA) 40W

In receive mode, the voltage control line is at ground level and turns off Q5473, which in turn
switches off the biasing voltage to U5401.

3.2

Pre-Driver Stage
The next stage is a 13dB gain LDMOS device (Q5421) which requires a positive gate bias and a
quiescent current flow for proper operation. The voltage of the line PCIC_MOSBIAS_1 is set in
transmit mode by PCIC, pin 24 and fed to the gate of Q5421 via the resistive network R5407,
R5408, R5416, and R5415. The bias voltage is factory tuned.

3.3

Driver Stage
This stage is an enhancement-mode N-Channel MOSFET device (Q5431) providing a gain of 10dB.
This device also requires a positive gate bias and a quiescent current flow for proper operation. The
voltage of the line Bias_2_UHF_PA_1 is set in transmit mode by the ASFIC and fed to the gate of
Q5431 via resistive network R5630, R5631, and R5632. This bias voltage is also factory tuned.
If the transistor is replaced, the bias voltage must be tuned using the Customer Programming
Software (CPS). Care must be taken not to damage the device by exceeding the maximum allowed
bias voltage. The device’s drain current is drawn directly from the radio’s DC supply voltage input,
A+ via L5421.

3.4

Final Stage
The final stage uses bipolar device Q5441 whose collector current is also drawn from the radio’s DC
supply voltage input. To maintain class C operation, the base is DC-grounded by series inductor
L5441 and bead L5440. A matching network consisting of C5541-C5544 and two striplines
transform the impedance to 50 ohms and also feed the directional coupler.

3.5

Bi-directional Coupler
The bi-directional coupler is a microstrip printed circuit, which couples a small amount of the forward
and reverse power of the RF power from Q5441. The coupled signal is rectified to an output power
proportional DC voltage by diodes D5451 and D5452 before being sent to the RFIN input of the
PCIC. The PCIC controls the gain of stage U5401 as necessary to hold this voltage constant. This
ensures the forward power out of the radio is held to a constant value.

3.6

Antenna Switch
The antenna switch utilizes the existing DC feed (A+) to the last stage device (Q5441). Basic
operation is to have both PIN diodes (D5471 and D5472) turned on during key-up by forward
biasing them. This is achieved by pulling down the voltage at the cathode end of D5472 to around
11.8V (0.7V drop across each diode). The current through the diodes needs to be set around 80mA
to fully open the transmit path through resistor R5496. Q5472 is a current source controlled by
Q5471 and is eventually connected to pin ANO of PCIC. VR5471 ensures the voltage at resistor
R4511 never exceeds 5.6V.

3.7

Chapter 10: 2-5

Harmonic Filter
Inductors L5491, L5492, and L4493 along with capacitors C5448, C5493, C5494, C5496, and
C5498 form a low-pass filter to attenuate harmonic energy from the transmitter. Resistor R5491
drains any electrostatic charges that might otherwise build up on the antenna. The harmonic filter
also prevents high level RF signals above the receiver passband from reaching the receiver circuits
to improve spurious response rejection.

3.8

Power Control
The transmitter uses the power control IC (PCIC, U5501) to control the power output of the radio. A
portion of the forward RF power from the transmitter is sampled by the bi-directional coupler and
rectified to provide a DC voltage to the RFIN port of the PCIC (pin 1) that is proportional to the
sampled RF power.
The PCIC has internal digital-to-analog converters (DACs) which provide a reference voltage to the
control loop. The reference voltage level is programmable through the SPI line of the PCIC and is
proportional to the desired power setting of the transmitter. Factory programming at several points
across the frequency range of the transmitter is used to offset frequency response variations of the
transmitter’s power detector circuits.
The PCIC provides a DC output voltage at pin 4 (INT) and applied as CNTLVLTG to the poweradjust input pin of the first transmitter stage U5401. This adjusts the transmitter power output to the
intended value. Variations in forward or reflected transmitter power cause the DC voltage at pin 1 to
change, and the PCIC adjusts the control voltage above or below its nominal value to raise or lower
output power.
Capacitor C5502-4, in conjunction with resistors and integrators within the PCIC, control the
transmitter power rise (key-up) and power decay (de-key) characteristic to minimize splatter into
adjacent channels.
U5502 is a temperature-sensing device, which monitors the circuit board temperature in the vicinity
of the transmitter driver and final devices, and provides a DC voltage to the PCIC (TEMP, pin 29)
proportional to temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the
transmitter output power is reduced to decrease the transmitter temperature.

4.0

UHF Band 2 (450-512/520 MHz) 25-40W Bipolar Frequency
Synthesis
The synthesizer, shown in Figure 10-3, consists of a reference oscillator (Y5261 or Y5262), low
voltage LVFRAC-N synthesizer (U5201), and a voltage controlled oscillator (VCO).

4.1

Reference Oscillator
The reference oscillator (Y5262) contains a temperature compensated crystal oscillator with a
frequency of 16.8 MHz. An analog-to-digital (A/D) converter internal to U5201 (LVFRAC-N) and
controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U5201, pin 25 to
set the frequency of the oscillator. The output of the oscillator (Y5262, pin 3) is applied to pin 23
(XTAL1) of U5201 via an RC series combination.

6881091C63-A

Chapter 10: 2-6

UHF Band 2 (450-512/520 MHz) 25-40W Bipolar Frequency Synthesis

In applications where less frequency stability is required, the oscillator inside U5201 is used along
with external crystal Y5261, varactor diode D5261, C5261, C5262, and R5262. In this case, Y5262,
R5263, C5235 and C5251 are not used. When Y5262 is used, Y5261, D5261, C5261, C5262 and
R5262 are not used, and C5263 is increased to 0.1 uF.

4.2

Fractional-N Synthesizer
The LVFRAC-N synthesizer IC (U5201) consists of a pre-scaler, programmable loop divider, control
divider logic, phase detector, charge pump, A/D converter for low frequency digital modulation,
balanced attenuator used to balance high frequency analog modulation and low frequency digital
modulation, 13V positive voltage multiplier, serial interface for control, and a super filter for the
regulated 5 volts.
A voltage of 5V applied to the super filter input (U5201, pin 30) supplies an output voltage of 4.5 Vdc
(VSF) at pin 28. It supplies the VCO, VCO modulation bias circuit (via R5322), and synthesizer
charge pump resistor network (R5251, R5252). The synthesizer supply voltage is provided by 5V
regulator, U5211.
To generate a high voltage to supply the phase detector (charge pump) output stage at pin VCP
(U5701-32), a voltage of 13 Vdc is generated by the positive voltage multiplier circuit (D5201,
C5202, and C5203). This voltage multiplier is basically a diode capacitor network driven by two
signals (1.05MHz) 180 degrees out of phase (U5201, pins 14 and 15).

UHF Band 2 (450-512/520 MHz) 25-40W Bipolar Frequency Synthesis

Chapter 10: 2-7

The serial interface (SRL) is connected to the µP via data line DATA (U5201-7), clock line CLK
(U5201-8), and chip enable line CSX (U5201-9).

4.3

Voltage Controlled Oscillator (VCO)
The voltage controlled oscillator (VCO), shown in Figure 10-4, consists of a VCO buffer IC
(VCOBIC, U5301), TX and RX tank circuits, external RX buffer stages, and modulation circuits.
The VCOBIC together with Fractional-N synthesizer (U5201) generates the required frequencies in
both transmit and receive modes. The TRB line (U5301, pin 19) determines which tank circuits and
internal buffers are to be enabled. A high level on TRB enables TX tank and TX output (pin 10), and
a low enables RX tank and RX output (pin 8). A sample of the signal from the enabled output is
routed from U5301, pin 12 (PRESC_OUT), via a low-pass filter of U5201, pin 32 (PREIN).
A steering line voltage (VCTRL) between 3.0V and 10.0V at varactor diode CR5311 tunes the full TX
frequency range (TXINJ) from 450 MHz to 512 (or 520) MHz, and at varactor diodes CR5301,
CR5302, and CR5303 tunes the full RX frequency range (RXINJ) from 405 MHz to 475 MHz. The
tank circuits uses the Hartley configuration for wider bandwidth. For the RX tank circuit, external
transistor Q5301 is used in conjunction with the internal transistor for better side-band noise.

UHF Band 2 (450-512/520 MHz) 25-40W Bipolar Frequency Synthesis

The external RX buffers (Q5332) are enabled by a high at U5201, pin 3 (AUX4) via transistor switch
Q5333. In TX mode, the modulation signal (VCOMOD) from the LVFRAC-N synthesizer IC (U5201,
pin 41) is applied to the modulation circuits CR5321, R5321, R5322, and C5324. These modulate
the TX VCO frequency via coupling capacitor C5321. Varactor CR5321 is biased for linearity from
the VSF.

4.4

Synthesizer Operation
The synthesizer consists of a low voltage FRAC-N (LVFRACN) IC, reference oscillator (crystal
oscillator with temperature compensation), charge pump circuits, loop filter circuits, and DC supply.
The output signal (PRESC_OUT) of the VCOBIC (U5301, pin12) is fed to of U5201, pin 32 (PREIN)
via a low-pass filter (C5229,L5225,and C5226) which attenuates harmonics and provides correct
level to close the synthesizer loop.
The pre-scaler in the synthesizer (U5201) is a dual modulus pre-scaler with selectable divider ratios.
The divider ratio of the pre-scaler is controlled by the loop divider, which in turn receives its inputs
via the SRL. The output of the pre-scaler is applied to the loop divider. The output of the loop divider
is connected to the phase detector, which compares the loop divider’s output signal with the
reference signal. The reference signal is generated by dividing down the signal of the reference
oscillator (Y5261 or Y5262).
The output signal of the phase detector is a pulsed DC signal routed to the charge pump. The
charge pump outputs a current at U5201, pin 43 (IOUT). The loop filter (consisting of R5221-R5223,
C5221-C5225, and L5221) transforms this current into a voltage that is applied to varactor diodes
CR5311 for transmit, CR5301, CR5302 and CR5303 for receive and alters the output frequency of
the VCO. The current can be set to a value fixed in the LVFRAC-N IC or to a value determined by
the currents flowing into BIAS 1 (U5201-40) or BIAS 2 (U5201-39). The currents are set by the value
of R5251 or R5252 respectively. The selection of the three different bias sources is done by
software programming.
To reduce synthesizer lock time, when new frequency data has been loaded into the synthesizer, the
magnitude of the loop current is increased by enabling the IADAPT (U5201-45) for a certain
software programmable time (Adapt Mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range, the current is determined
only by the resistors connected to BIAS 1, BIAS 2, or the internal current source. A settled
synthesizer loop is indicated by a high level of signal LOCK (U5201-4) which is routed to one of the
µP’s ADCs input U101-56. From the voltage the µP determines whether LOCK is active.
To modulate the PLL, the two-spot modulation method is utilized via pin 10 (MODIN) on U5201. The
audio signal is applied to both the A/D converter (low frequency path) and the balanced attenuator
(high frequency path). The A/D converter converts the low frequency analog modulating signal into a
digital code which is applied to the loop divider, thereby causing the carrier to deviate. The balance
attenuator is used to adjust the VCO’s deviation sensitivity to high frequency modulating signals.
The output of the balance attenuator is present at the MODOUT port (U5201-41) and connected to
the VCO modulation diode CR5321 via R5321 and C5325.

Introduction
This chapter provides a detailed theory of operation for the VHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

VHF (136-174 MHz) 25-45W LDMOS Receiver Front-End

2.1

Receiver Front-End
The receiver is able to cover the VHF range from 136 to 174 MHz. It consists of four major blocks:
front-end bandpass filters and pre-amplifier, first mixer, 1st IF, 2nd IF, and receiver back-end. Two
varactor-tuned bandpass filters perform antenna signal pre-selection. A passive double-balanced
mixer converts the signal to the first IF of 44.85 MHz. High-side injection is used.

Chapter 11: 2-2

VHF (136-174 MHz) 25-45W LDMOS Receiver Front-End

There are two 2-pole 44.85 MHz crystal filters in the 1st IF section and 2 pairs of 455 kHz ceramic
filters in the 2nd IF section to provide the required adjacent channel selectivity. The correct pair of
ceramic filters for 12.5 or 25kHz channel spacing is selected via control line BWSELECT. The
second IF at 455 kHz is mixed, amplified and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuits, before being applied to the
receiver pre-selector filter (C3001, C3002, D3001 and associated components). The 2-pole preselector filter tuned by the dual varactor diode D3001 pre-selects the incoming signal (RXIN) from
the antenna switch to reduce spurious effects to following stages. The tuning voltage (FECTRL_1)
ranging from 2 volts to 8 volts is controlled by pin 20 of PCIC (U3501) in the Transmitter section. A
dual hot carrier diode (D3003) limits any inband signal to 0 dBm to prevent damage to the preamplifier.
The RF pre-amplifier is a surface mount device (SMD) Q3001 with collector-base feedback to
stabilize gain, impedance, and intermodulation. Transistor Q3002 compares the voltage drop across
resistor R3002 with a fixed base voltage from divider R3011, R3000 and R3012, and adjusts the
base current of Q3001 as necessary to maintain its collector current constant at approximately 1520 mA. Operating voltage is from the regulated 9.3V supply (9V3). During transmit, 9.1 volts (K9V1)
turns off both transistors Q3002 and Q3001. This protects the RF pre-amplifier from excessive
dissipation during transmit mode. A following 3dB pad (R3006 – R3008 and R3016 – R3018)
stabilizes the output impedance and intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
The dual varactor diode D3004 is controlled by the same signal FECTRL_1, which controls the preselector filter.

2.3

First Mixer and 1st Intermediate Frequency (IF)
The signal coming from the front-end is converted to the 1st IF frequency of 44.85 MHz using a
passive double-balanced mixer (D3031). Its ports are matched for incoming RF signal conversion to
the 44.85 MHz IF using high side injection. The high-side injection signal (RXINJ) from the
frequency synthesizer circuit has a level of approximately +13 dBm and is injected via matching
transformer T3002.
The IF output signal (IF) from transformer T3001 pin 2 is fed to the first 2-pole crystal filter FL3101.
The filter output in turn is matched to IF amplifier Q3101 which is actively biased by a collector base
feedback (R3101, R3106) to a current drain of approximately 5 mA drawn from the 5 volt supply. Its
output impedance is matched to the second 2-pole crystal filter FL3102. The signal is further
amplified by a pre-amplifier (Q3102) before going into pin 1 of IFIC (U3101).
A dual hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

2.4

2nd Intermediate Frequency (IF) and Receiver Back-End
The 44.85 MHz 1st IF signal from the second IF amplifier feeds the IF IC (U3101) at pin1. Within the
IF IC, the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator (2nd LO) to
produce the 2nd IF signal at 455 kHz. The 2nd LO frequency is determined by crystal Y3101. The
2nd IF signal is amplified and filtered by an external pair of 455 kHz ceramic filters FL3112, FL3114
for 20/25 kHz channel spacing or FL3111, FL3113/F3115 for 12.5 kHz channel spacing. These pairs
are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the limiter
input pin of the IF IC (pin 14).

VHF (136-174 MHz) 25-45W LDMOS Transmitter Power Amplifier (PA) 45W

Chapter 11: 2-3

The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U3101 pin 8 (DISCAUDIO) which is fed to the ASFIC_CMP (U0221) pin 2 (part of
the Controller circuits).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101, pin 5, having a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101, pin 63) and in addition is available
at accessory connector J0501-15.

3.0

VHF (136-174 MHz) 25-45W LDMOS Transmitter Power Amplifier
(PA) 45W
The radio’s 45W PA is a three-stage amplifier used to amplify the output from the VCOBIC to the
radio transmit level. All three stages utilize LDMOS technology. The gain of the first stage (U3401) is
adjustable, controlled by pin 4 of PCIC (U3501) via U3402-1. It is followed by an LDMOS driver
stage (Q3421) and an LDMOS final stage (Q3441). All devices are surface mounted. A pressure
pad between the board and the radio’s cover provides both closure of the switch and insurance of
good thermal contact between the devices and the chassis.

3.1

Power Controlled Stage
The first stage (U3401) is a 20 dB gain integrated circuit containing two LDMOS FET amplifier
stages. It amplifies the RF signal from the VCO (TXINJ). The output power of stage U3401 is
controlled by a DC voltage applied to pin 1 from the power control circuit (U3501 pin 4, with
operational amplifier U3402-1, pin 1). The control voltage simultaneously varies the bias of two FET
stages within U3401. This biasing point determines the overall gain of U3401 and therefore its
output drive level to Q3421, which in turn controls the output power of the PA.
Op-amp U3402-1 monitors the drain current of U3401 via resistor R3444 and adjusts the bias
voltage of U3401 so that the current remains constant. The PCIC (U3501) provides a DC output
voltage at pin 4 (INT) which sets the reference voltage of the current control loop. A rising power
6881091C63-A

Chapter 11: 2-4

VHF (136-174 MHz) 25-45W LDMOS Transmitter Power Amplifier (PA) 45W

output causes the DC voltage from the PCIC to fall, and U3402-1 adjusts the bias voltage for a lower
drain current to lower the gain of the stage.
In receive mode the DC voltage from PCIC pin 23 (RX) turns on Q3442, which in turn switches off
the biasing voltage to U3401.
Switch S3440 is a pressure pad with a conductive strip, which connects two conductive areas on the
board when the radio’s cover is properly screwed to the chassis. When the cover is removed, S3440
opens and the resulting high voltage level at the inverting inputs of the current control op-amps
U3402-1 switches off the biasing of U3401. This prevents transmitter key-up while the devices do
not have proper thermal contact to the chassis.

3.2

Driver Stage
The next stage is an LDMOS device (Q3421) providing a gain of 13 dB. This device requires a
positive gate bias and a quiescent current flow for proper operation. The voltage of the line
MOSBIAS_1 is set during transmit mode by PCIC pin 24 and fed to the gate of Q3421 via the
resistive network R3417, R3415, and R3416. This bias voltage is tuned in the factory.
In receive mode, the MOSBIAS_1 supplied to Q3421 is grounded by the PCIC.

3.3

Final Stage
The final stage is an LDMOS MRF1550 device (Q3441). It provides a gain of 10 dB. This device also
requires a positive gate bias and a quiescent current flow for proper operation. The voltage of the
line MOSBIAS_2 is set during transmit mode by the ASFIC and fed to the gate of Q3441 via the
resistive network R3404, R3406, and R3431-2. This bias voltage is tuned in the factory. If the
transistor is replaced, the bias voltage must be tuned using Global Tuner Software. Care must be
taken not to damage the device by exceeding the maximum allowed bias voltage.
In receive mode, MOSBIAS_2 voltage is reduced to switch off Q3441.
The drain current of MRF1550 is drawn from the radio DC supply via filtering beads, bypass
capacitors and a current-sensing resistor (R3518). A differential DC amplifier U3503-1 compares the
voltage drop across R3518, which is proportional to the transmitter final stage DC current, with the
voltage across resistors R3511 and R3510, which is proportional to the current through transistor
Q1503. This transistor is controlled by the output of the differential amplifier, which varies the
transistor current until equilibrium of the two compared voltages is reached. The current through
Q1503 develops a voltage across R3517, which is exactly proportional to the DC current of the final
stage. This voltage is combined with power-sensing and temperature-sensing inputs and applied to
the RFIN port of the PCIC (pin 1).

3.4

Antenna Switch
The antenna switch consists of two PIN diodes, D3471 and D3472. In receive mode, both diodes
are off. Signals applied at the antenna jack J3401 are routed, via the coupler and harmonic filter,
through network L3511, C3451 and C3475, to the receiver input. In transmit mode, the keyed 9 volts
turns on Q3471 which enables current sink Q3472, set to 96 mA by R3473 and VR3471. This
completes a DC path from A+, through L3436, R3518, L3437, L3443, D3471, L3510, L3511, D3472,
L3471, and R3474 and the current sink, to ground. Both diodes are forward biased into conduction.
The transmitter RF from the PA is routed via D3471, C3561 and C3563 to the harmonic filter,
directional coupler and antenna jack. D3472 also conducts, shunting RF power and preventing it
from reaching the receiver port (RXIN). L3511 is selected to appear as a broadband quarter-wave
transmission line, making the short circuit presented by D3472 appear as an open circuit at the
junction of D3472 and the receiver path.

3.5

Chapter 11: 2-5

Harmonic Filter
Components L3512-L3515 and C3564-C3568 form a nine-pole Chebychev low-pass filter and
attenuate harmonic energy of the transmitter. R3545 is used to drain electrostatic charge that might
otherwise build up on the antenna. The harmonic filter also prevents high-level RF signals above the
receiver passband from reaching the receiver circuits, improving spurious response rejection.

3.6

Directional Coupler
The directional coupler is a microstrip printed circuit, which couples a small amount of the forward
and reflected power delivered by Q3441. The coupled signals are rectified by D3451-2 and
combined by R3540-1. The resulting DC voltage is proportional to RF output power. This RF powersensing signal later is combined with the current-sensing signal from U3503 and Q1503 as well as
the temperature-sensing signal from RT3501 and fed to the RFIN port of the PCIC (U3501, pin 1).
The PCIC controls the gain of stage U3401 as necessary to hold the sum of these signals constant,
thus ensuring the forward power out of the radio to be held to a constant value.
An abnormally high reflected power level, such as may be caused by a damaged antenna, also
causes the DC voltage applied to the PCIC to increase, and this will cause a reduction in the gain of
U3401, reducing transmitter output power to prevent damage to the final device due to an improper
load.

3.7

Power Control
The transmitter uses the power control IC (PCIC, U3501) to control the power output of the radio. A
portion of the forward and reflected RF power from the transmitter is sampled by the directional
coupler, rectified and summed, to provide a DC voltage to the RFIN port of the PCIC (pin 1) which is
proportional to the sampled RF power.
The ASFIC contains a digital-to-analog converter (DAC) which provides a reference voltage of the
control loop to the PCIC via R3505. The reference voltage level is programmable through the SPI
line of the PCIC. This reference voltage is proportional to the desired power setting of the
transmitter, and is factory programmed at several points across the frequency range of the
transmitter to offset frequency response variations of the transmitter’s power detector circuit.
The PCIC provides a DC output voltage at pin 4 (INT) which is amplified by U3402-1, and applied to
the power-adjust input pin of the first transmitter stage U3401. This adjusts the transmitter power
output to the intended value. Variations in forward or reflected transmitter power cause the DC
voltage at pin 1 to change, and the PCIC adjusts the control voltage above or below its nominal
value to raise or lower output power.
Capacitors C3502-4, in conjunction with resistors and integrators within the PCIC, control the
transmitter power-rise (key-up) and power-decay (de-key) characteristic to minimize splatter into
adjacent channels.
U3502 is a temperature-sensing device, which monitors the circuit board temperature in the vicinity
of the transmitter driver and final devices, and provides a DC voltage to the PCIC (TEMP, pin 29)
proportional to temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the
transmitter output power is reduced so as to reduce the transmitter temperature.

The frequency synthesizer subsystem consists of the reference oscillator (Y3261 or Y3262), the

The reference oscillator (Y3262) contains a temperature compensated crystal oscillator with a
frequency of 16.8 MHz. An analog-to-digital (A/D) converter internal to U3201 (LVFRAC-N) and
controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U3201 (pin 25)
to set the frequency of the oscillator. The output of the oscillator (U3262 pin 3) is applied to pin 23
(XTAL1) of U3201 via R3263 and C3235.
In applications where less frequency stability is required, the oscillator inside U3201 is used along
with an external crystal Y3261, varactor diode D3261, C3261, C3262 and R3262. In this case,
Y3262, R3263, C3235 and C3251 are not used. When Y3262 is used, Y3261, D3261, C3261,

In order to generate a high voltage to supply the phase detector (charge pump) output stage at pin
VCP (U3201-47), a voltage of 13 VDC is being generated by the positive voltage multiplier circuits
(D3201, C3202, C3203). This voltage multiplier is basically a diode capacitor network driven by two
signals (1.05MHz) 180 degrees out of phase signals (U3201-14 and -15).
Output LOCK (U3201-4) provides information about the lock status of the synthesizer loop. A high
level at this output indicates a stable loop. IC U3201 provides the 16.8 MHz reference frequency at

frequency range (RXINJ) from 181 MHz to 219 MHz. The RX tank circuit uses a Hartley
configuration for wider bandwidth. For the RX tank circuit, an external transistor Q3304 is used for
better side-band noise.
The external RX buffers (Q3301 and Q3302) are enabled by a high at U3301, pin 7 (RX_SWITCH)
via transistor switch Q3303. In the TX mode, the modulation signal (VCOMOD) from the LVFRAC-N
synthesizer IC (U3201 pin 41) is applied to varactor diode D3362, which modulates the TX VCO
frequency via capacitor C3362. Varactor D3362 is biased for linearity from the VSF.

Synthesizer Operation
The complete synthesizer subsystem consists of the low voltage FRAC-N (LVFRACN), reference
oscillator (a crystal oscillator with temperature compensation), charge pump circuit, loop filter circuit
and a DC supply. The output signal PRESC from the VCOBIC (U3301 pin 12) is fed to U3201 pin 32
(PREIN) via a low-pass filter (C3318, L3318 and C3226) which attenuates harmonics and provides
the correct level to close the synthesizer loop.
The pre-scaler in the synthesizer (U3201) is a dual modulus type with selectable divider ratios. The
divider ratio of the pre-scaler is controlled by the loop divider, which in turn receives its inputs via the
SRL. The output of the pre-scaler is applied to the loop divider. The output of the loop divider is
connected to the phase detector, which compares the loop divider’s output signal with the reference
signal. The reference signal is generated by dividing down the signal of reference oscillator Y3261
or Y3262.
The output signal of the phase detector is a pulsed DC signal which is routed to the charge pump.
The charge pump outputs a current at U3201 pin 43 (IOUT). The loop filter (which consists of
R3221-R3223 and C3221-C3224) transforms this current into a voltage that is applied to the
varactor diodes (D3361 for transmit, D3341 for receive) to alter the output frequency of the
appropriate VCO. The current can be set to a value fixed within the LVFRAC-N IC, or to a value
determined by the currents flowing into BIAS 1 (U3201-40) or BIAS 2 (U3201-39). The currents are
set by the value of R3251 and R3252 respectively. The selection of the three different bias sources
is done by software programming.
To reduce synthesizer lock time when new frequency data has been loaded into the synthesizer, the
magnitude of the loop current is increased by enabling the IADAPT pin (U3201-45) for a certain
software programmable time (adapt mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range, the current is determined
only by the resistors connected to BIAS 1 and BIAS 2, or by the internal current source. A settled
synthesizer loop is indicated by a high level signal at U3201-4 (LOCK).
The LOCK signal is routed to one of the µP’s ADC inputs (U0101-56). From the measured voltage,
the µP determines whether LOCK is active.
To modulate the PLL, the two spot modulation method is utilized. Via U3201, pin 10 (MODIN), the
audio signal is applied to both the A/D converter (low frequency path) as well as the balance
attenuator (high frequency path). The A/D converter changes the low frequency analog modulating
signal into a digital code that is applied to the loop divider, thereby causing the carrier to deviate.
The balance attenuator is used to adjust the VCO’s deviation sensitivity to high frequency
modulating signals. The output of the balance attenuator is present at the MODOUT port (U320141) and connected to the VCO modulation diode D3362 via R3364.

Introduction
This chapter provides a detailed theory of operation for the UHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of this manual.

UHF Band 1 (403-470 MHz) 25-40W LDMOS Receiver Front-End

2.1

Receiver Front-End
The receiver is able to cover the UHF range from 403 to 470 MHz. It consists of four major blocks:
front-end bandpass filters and pre-amplifier, first mixer, high-IF, low-IF and receiver back-end. Two
varactor-tuned bandpass filters perform antenna signal pre-selection. A passive double-balanced
mixer converts the signal to the first IF of 44.85 MHz. Low-side first injection is used.

Chapter 12: 2-2

UHF Band 1 (403-470 MHz) 25-40W LDMOS Receiver Front-End

There are two 2-pole 44.85 MHz crystal filters in the high-IF section and 2 pairs of 455 kHz ceramic
filters in the low-IF section to provide the required adjacent channel selectivity. The correct pair of
ceramic filters for 12.5 or 25 kHz channel spacing is selected via control line BWSELECT. The
second IF at 455 kHz is mixed, amplified and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuitry, before being applied to the
receiver pre-selector filter (C4001, C4002, D4001 and associated components). The 2-pole preselector filter tuned by the varactor diodes D4001 and D4002 pre-selects the incoming signal (RXIN)
from the antenna switch to reduce spurious effects to following stages. The tuning voltage
(FECTRL_1) ranging from 2 volts to 8 volts is controlled by pin 20 of PCIC (U4501) in the
Transmitter section. A dual hot carrier diode (D4003) limits any inband signal to 0 dBm to prevent
damage to the pre-amplifier.
The RF pre-amplifier is an SMD device (Q4003) with collector base feedback to stabilize gain,
impedance, and intermodulation. The collector current of approximately 11-16 mA is drawn from the
9.3V supply via L4003 and R4002. A switchable 3dB pad (R4066, R4007, R4063, R4064 and
R4070), controlled via line FECTRL_2 and Q4004 stabilizes the output impedance and
intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
The varactor diodes D4004 and D4005 are controlled by the same signal FECTRL_1, which
controls the pre-selector filter. A following 1 dB pad (R4013 - R4015) stabilizes the output
impedance and intermodulation performance.

2.3

First Mixer and High Intermediate Frequency (IF)
The signal coming from the front-end is converted to the first IF (44.85 MHz) using a passive doublebalanced mixer (D4051). Its ports are matched for incoming RF signal conversion to the 44.85 MHz
IF using low side injection via matching transformers T4051 and T4052. The injection signal (RXINJ)
coming from the RX VCO buffer (Q4332) is filtered by the low-pass filter consisting of (L4053,
L4054, C4053 - C4055) followed by a matching transformer T4052 and has a level of approximately
15dBm.
The mixer IF output signal (IF) from transformer T4501pin 2 is fed to the first two pole crystal filter
FL3101. The filter output in turn is matched to the following IF amplifier.
The IF amplifier Q3101 is actively biased by a collector base feedback (R3101, R3106) to a current
drain of approximately 5 mA drawn from the voltage 5V. Its output impedance is matched to the
second two pole crystal filter FL3102. The signal is further amplified by a pre-amplifier (Q3102)
before going into pin 1 of IFIC (U3101).
A dual hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

2.4

Chapter 12: 2-3

Low Intermediate Frequency (IF) and Receiver Back-End
The 44.85 high IF signal from the second IF amplifier feeds the IF IC (U3101) at pin1. Within the IF
IC the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator (2nd LO) to
produce the low IF signal at 455 kHz. The 2nd LO frequency is determined by crystal Y3101. The
low IF signal is amplified and filtered by an external pair of 455 kHz ceramic filters FL3112, FL3114
for 20/25 kHz channel spacing or FL3111,FL3113/F3115 for 12.5 kHz channel spacing. These pairs
are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the limiter
input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U3103 pin 8 (DISCAUDIO) which is fed to the ASFIC_CMP (U0221) pin 2 (part of
the controller circuitry).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101 pin 5, having a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101 pin 63) and in addition is available
at accessory connector J0501-15.

3.0

UHF Band 1 (403-470 MHz) 25-40W LDMOS Transmitter Power
Amplifier (PA) 40W
The radio’s 40W PA is a three-stage amplifier used to amplify the output from the VCOBIC to the
radio transmit level. All three stages utilize LDMOS technology. The gain of the first stage (U4401) is
adjustable, controlled by pin 4 of PCIC (U4501). It is followed by an LDMOS stage (Q4421) and
LDMOS final stage (Q4441).

Devices U4401, Q4421 and Q4441 are surface mounted. A pressure pad between the board and
the radio's cover provides good thermal contact between the devices and the chassis.

Chapter 12: 2-4

3.1

UHF Band 1 (403-470 MHz) 25-40W LDMOS Transmitter Power Amplifier (PA) 40W

First Power Controlled Stage
The first stage (U4401) is a 20dB gain integrated circuit containing two LDMOS FET amplifier
stages. It amplifies the RF signal from the VCO (TXINJ). The output power of stage U4401 is
controlled by a DC voltage applied to pin 1 from Q4473. The control voltage simultaneously varies
the bias of two FET stages within U4401. This biasing point determines the overall gain of U4401
and therefore its output drive level to Q4421, which in turn controls the output power of the PA.
Switch S4440 is a pressure pad with a conductive strip which connects two conductive areas on the
board when the radio's cover is properly screwed to the chassis. When the cover is removed, S4440
opens and cuts the supply voltage to Q4473 thus disabling control voltage to U4401. This prevents
transmitter key up while the devices do not have proper thermal contact to the chassis.

3.2

Power Controlled Driver Stage
The next stage is an LDMOS device (Q4421) providing a gain of 12dB. This device requires a
positive gate bias and a quiescent current flow for proper operation. The bias is set during transmit
mode by U4501-24 and fed to the gate of Q4421 via the resistive network R4480, R4408, R4415
and R4416.

3.3

Final Stage
The final stage is an LDMOS MRF 1570 device Q4441. It provides a gain of 11dB. It integrates two
MRF1535 die inside. These two die are being run in parallel. The output of each of the device (die)
inside are combined to constitute the total output power. This device also requires a positive gate
bias and a quiescent current flow for proper operation. The voltage of the line MOSBIAS_2 and
MOSBIAS_3 are set in transmit mode by the ASFIC and fed to the gate of Q4441 via two resistive
network R4631, R4634, R4485, R4486 and R4632, R4635, R4481, R4489. These bias voltages are
tuned in the factory. If the transistor is replaced, the bias voltage must be tuned using the Global
Tuner. Care must be taken not to damage the device by exceeding the maximum allowed bias
voltage. The device’s drain current is drawn directly from the radio’s DC supply voltage input,
PASUPVLTG, via L4421, L4437 and L4436, L4438.
A matching network consisting of C4440-45, C4466-67, C4476-77, C4487, C4491, C4489, C4490,
C4455-56, C4449-50 and striplines transforms the impedance to 50 ohms and feeds the directional
coupler.

3.4

Directional Coupler
The directional coupler is a microstrip printed circuit, which couples a small amount of the forward
power delivered by Q4441. The coupled signal is rectified by D4451. The DC voltage is proportional
to the RF output power and feeds the RFIN port of the PCIC (U4501 pin 1). The PCIC controls the
gain of stage U4401 as necessary to hold this voltage constant, thus ensuring the forward power out
of the radio to be held to a constant value.

3.5

Antenna Switch
The antenna switch consists of two PIN diodes, D4471 and D4472. In the receive mode, both diodes
are off. Signals applied at the antenna jack J4401 are routed, via the harmonic filter, through
network L4472, C4474 and C4475, to the receiver input. In the transmit mode, K9V1 turns on
Q4471 which enables current sink Q4472, set to 96 mA by R4512 and VR4471. This completes a

6881091C63-A

Chapter 12: 2-5

DC path from PASUPVLTG, through L4437, D4471, L4472, D4472, L4473, R4496 and the current
sink, to ground. Both diodes are forward biased into conduction. The transmitter RF from the
directional coupler is routed via D4471 to the harmonic filter and antenna jack. D4472 also
conducts, shunting RF power and preventing it from reaching the receiver port (RXIN). L4472 is
selected to appear as a broadband lambda/4 wave transmission line, making the short circuit
presented by D4472 appear as an open circuit at the junction of D4472 and the receiver path.

3.6

Harmonic Filter
Components L4491-L4493 and L4472, C4448, C4494, C4496 and C4498 form a Butterworth lowpass filter to attenuate harmonic energy of the transmitter to specifications level. R4491 is used to
drain electrostatic charge that might otherwise build up on the antenna. The harmonic filter also
prevents high level RF signals above the receiver passband from reaching the receiver circuits,
improving spurious response rejection.

3.7

Power Control
The transmitter uses the Power Control IC (PCIC, U4501) to control the power output of the radio. A
portion of the forward RF power from the transmitter is sampled by the directional coupler and
rectified, to provide a DC voltage to the RFIN port of the PCIC (pin 1) which is proportional to the
sampled RF power.
The ASFIC (U0221) has internal digital-to-analog converters (DACs) which provide a reference
voltage of the control loop to the PCIC via R4483. The reference voltage level is programmable
through the SPI line of the PCIC. This reference voltage is proportional to the desired power setting
of the transmitter, and is factory programmed at several points across the frequency range of the
transmitter to offset frequency response variations of the transmitter’s power detector circuit.
The PCIC provides a DC output voltage at pin 4 (INT) which sets the drain current of the first
(U4401). This adjusts the transmitter power output to the intended value. Variations in forward
transmitter power cause the DC voltage at pin 1 to change, and the PCIC adjusts the control voltage
above or below its nominal value to raise or lower output power.
Capacitors C4502-4, in conjunction with resistors and integrators within the PCIC, control the
transmitter power-rise (key-up) and power-decay (de-key) characteristic to minimize splatter into
adjacent channels.
U4502 is a temperature-sensing device, which monitors the circuit board temperature in the vicinity
of the transmitter driver and final devices, and provides a DC voltage to the PCIC (TEMP, pin 30)
proportional to temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the
transmitter output power will be reduced so as to reduce the transmitter temperature.

UHF Band 1 (403-470 MHz) 25-40W LDMOS Frequency Synthesis

Reference Oscillator
The reference oscillator (Y4262) contains a temperature compensated crystal oscillator with a
frequency of 16.8 MHz. An analog-to-digital (A/D) converter internal to U4201 (LVFRAC-N) and
controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U4201 pin 25 to
set the frequency of the oscillator. The output of the oscillator (pin 3 of Y4262) is applied to pin 23
(XTAL1) of U4201 via a RC series combination.
In applications where less frequency stability is required the oscillator inside U4201 is used along
with an external crystal Y4261, varactor diode D4261, C4261, C4262 and R4262. In this case,
Y4262, R4263, C4235 and C4251 are not used. When Y4262 is used, Y4261, D4261, C4261,
C4262 and R4262 are not used, and C4263 is increased to 0.1 uF.

Chapter 12: 2-7

In order to generate a high voltage to supply the phase detector (charge pump) output stage at
pin 47 VCP (U4201-47), a voltage of 13 VDC is being generated by the positive voltage multiplier
circuitry (D4201, C4202, C4203). This voltage multiplier is basically a diode capacitor network driven
by two (1.05MHz) 180 degrees out of phase signals (U4201-14 and -15).
Output LOCK (U4201-4) provides information about the lock status of the synthesizer loop. A high
level at this output indicates a stable loop. IC U4201 provides the 16.8 MHz reference frequency at
pin 19.
The serial interface (SRL) is connected to the µP via the data line DATA (U4201-7), clock line CLK
(U4201-8), and chip enable line CSX (U4201-9).

a low enables RX tank and RX output (pin 8). A sample of the signal from the enabled output is
routed from U4301 pin 12 (PRESC_OUT), via a low-pass filter, to pin 32 of U4201 (PREIN).
A steering line voltage (VCTRL) between 3.0V and 10.0V at varactor diode CR4311 will tune the full
TX frequency range (TXINJ) from 403 MHz to 470 MHz, and at varactor diodes CR4301, CR4302
and CR4303 will tune the full RX frequency range (RXINJ) from 358 MHz to 425 MHz. The tank
circuits uses the Hartley configuration for wider bandwidth. For the RX tank circuit, an external
transistor Q4301 is used in conjunction with the internal transistor for better side-band noise.
The external RX buffers (Q4332) are enabled by a high at U4201 pin 3 (AUX4) via transistor switch
Q4333. In TX mode the modulation signal (VCOMOD) from the LVFRAC-N synthesizer IC (U4201
pin41) is applied modulation circuitry CR4321, R4321, R4322 and C4324, which modulates the TX
VCO frequency via coupling capacitor C4321. Varactor CR4321 is biased for linearity from VSF.

4.4

Synthesizer Operation
The complete synthesizer subsystem comprises mainly of low voltage FRAC-N (LVFRACN) IC,
Reference Oscillator (crystal oscillator with temperature compensation), charge pump circuitry, loop
filter circuitry and DC supply. The output signal PRESC_OUT of the VCOBIC (U4301 pin 12) is fed
to pin 32 of U4201 (PREIN) via a low-pass filter (C4229, L4225) which attenuates harmonics and
provides the correct level to close the synthesizer loop.
The pre-scaler in the synthesizer (U4201) is basically a dual modulus pre-scaler with selectable
divider ratios. This divider ratio of the pre-scaler is controlled by the loop divider, which in turn
receives its inputs via the SRL. The output of the pre-scaler is applied to the loop divider. The output
of the loop divider is connected to the phase detector, which compares the loop divider’s output
signal with the reference signal. The reference signal is generated by dividing down the signal of the
reference oscillator (Y4261 or Y4262).
The output signal of the phase detector is a pulsed DC signal which is routed to the charge pump.
The charge pump outputs a current at pin 43 of U4201 (IOUT). The loop filter (which consists of
R4221-R4223, C4221-C4225,L4221) transforms this current into a voltage that is applied to the
varactor diodes CR4311 for transmit, CR4301, CR4302 & CR4303 for receive and alters the output
frequency of the VCO. The current can be set to a value fixed in the LVFRAC-N IC or to a value
determined by the currents flowing into BIAS 1 (U4201-40) or BIAS 2 (U4201-39). The currents are
set by the value of R4251 or R4252 respectively. The selection of the three different bias sources is
done by software programming.
To reduce synthesizer lock time when new frequency data has been loaded into the synthesizer the
magnitude of the loop current is increased by enabling the IADAPT (U4201-45) for a certain
software programmable time (Adapt Mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range the current is determined
only by the resistors connected to BIAS 1, BIAS 2, or the internal current source. A settled
synthesizer loop is indicated by a high level of signal LOCK (U4201-4).
The LOCK (U4201-4) signal is routed to one of the µP’s ADCs input U101-56. From the voltage the
µP determines whether LOCK is active. In order to modulate the PLL the two spot modulation
method is utilized. Via pin 10 (MODIN) on U4201 the audio signal is applied to both the A/D
converter (low freq path) as well as the balance attenuator (high freq path). The A/D converter
converts the low frequency analog modulating signal into a digital code that is applied to the loop
divider, thereby causing the carrier to deviate. The balance attenuator is used to adjust the VCO’s
deviation sensitivity to high frequency modulating signals. The output of the balance attenuator is
present at the MODOUT port (U4201-41) and connected to the VCO modulation diode CR4321 via
R4321, C4325.

THEORY OF OPERATION

Introduction
This chapter provides a detailed theory of operation for the UHF circuits in the radio. For details of
the theory of operation and troubleshooting for the associated controller circuits refer to the
controller section of the manual.

2.0

UHF Band 2 (450-512/520 MHz) 25-40W LDMOS Receiver Front-End

2.1

Receiver Front-End
The UHF receiver, shown in Figure 13-1, is able to cover the UHF range from 450 to 512 MHz (for
CDM models) and from 450 to 520 MHz (for PRO models). It consists of four major blocks: front-end
bandpass filters and pre-amplifier, first mixer, high-IF, low-IF and receiver back-end. Two varactortuned bandpass filters perform antenna signal pre-selection. A passive double-balanced mixer
converts the signal to the first IF of 44.85 MHz. Low-side first injection is used.

Chapter 13: 2-2

UHF Band 2 (450-512/520 MHz) 25-40W LDMOS Receiver Front-End

The two 2-pole 44.85 MHz crystal filters in the high-IF section and two pairs of 455 kHz ceramic
filters in the low-IF section provide the required adjacent channel selectivity. The correct pair of
ceramic filters for 12.5 or 25 kHz channel spacing is selected via control line BWSELECT. The
second IF at 455 kHz is mixed, amplified, and demodulated in the IF IC. The processing of the
demodulated audio signal is performed by an audio processing IC located in the controller section.

2.2

Front-End Bandpass Filters and Pre-Amplifier
The received signal from the radio’s antenna connector is first routed through the harmonic filter and
antenna switch, which are part of the RF power amplifier circuits, before being applied to the
receiver pre-selector filter (C5001, C5002, D5001, and related components). The 2-pole preselector filter, tuned by the varactor diodes D5001 and D5002, pre-select the incoming signal (RXIN)
from the antenna switch to reduce spurious effects to the stages that follow. The tuning voltage
(FECTRL_1), ranging from 2 volts to 8 volts, is controlled by pin 20 of PCIC (U5501) in the
transmitter section. A dual hot carrier diode (D5003) limits any inband signal to 0 dBm to prevent
damage to the pre-amplifier.
The RF pre-amplifier is an SMD device (Q5003) with collector base feedback to stabilize gain,
impedance, and intermodulation. The collector current of approximately 11-16 mA is drawn from the
9.3 volt supply via L5003 and R5002. A 3 dB pad (R5006, R5007, R5011, and R5008 - R5010)
stabilizes the output impedance and intermodulation performance.
A second 2-pole varactor tuned bandpass filter provides additional filtering of the amplified signal.
Varactor diodes D5004 and D5005 are controlled by the same signal, FECTRL_1, which controls
the pre-selector filter. A following 1 dB pad (R5013 - R5015) stabilizes the output impedance and
intermodulation performance.

2.3

First Mixer and High Intermediate Frequency (IF)
The signal from the front-end is converted to the first IF (44.85 MHz) using passive double-balanced
mixer D5051. Its ports are matched for incoming RF signal conversion to the 44.85 MHz IF using low
side injection via matching transformers T5051 and T5052. The injection signal (RXINJ) coming
from the RX VCO buffer (Q5332) is filtered by the low-pass filter consisting of L5053, L5054, and
C5053 - C5055 followed by matching transformer T5052 which has a level of approximately 15
dBm.
The mixer IF output signal from transformer T5501, pin 2 is fed to the first two-pole crystal filter
(FL3101). The filter output in turn is matched to IF amplifier Q3101 which is actively biased using
collector-base feedback resistors R3101and R3106 to provide a current drain of approximately 5
mA drawn from the 5 volt supply. The output impedance of this device is matched to the second twopole crystal filter FL3102. The signal is further amplified by a pre-amplifier Q3102 before going to pin
1 of IFIC (U3101).
A dual, hot carrier diode (D3101) limits the filter output voltage swing to reduce overdrive effects at
RF input levels above -27 dBm.

2.4

Low Intermediate Frequency (IF) and Receiver Back-End
The 44.85 MHz first IF signal from the second IF amplifier feeds the IF IC (U3101) at pin1. Within the
IF IC the 44.85 MHz high IF signal mixes with the 44.395 MHz second local oscillator to produce a
low IF signal of 455 kHz. The second LO frequency is determined by crystal Y3101. The second IF
signal is amplified and filtered by an external pair of 455 kHz ceramic filters (FL3112 and FL3114) for

6881091C63-A

UHF Band 2 (450-512/520 MHz) 25-40W LDMOS Transmitter Power Amplifier (PA) 40W

Chapter 13: 2-3

20/25 kHz channel spacing, or FL3111 and FL3113/F3115 for 12.5 kHz channel spacing. These
pairs are selectable via BWSELECT. The filtered output from the ceramic filters is applied to the
limiter input pin of the IF IC (pin 14).
The IF IC contains a quadrature detector using a ceramic phase-shift element (Y3102) to provide
audio detection. Internal amplification provides an audio output level of 120 mV rms (at 60%
deviation) from U3103, pin 8 (DISCAUDIO) which is fed to ASFIC_CMP U0221, pin 2 (part of the
controller circuits).
A Receive Signal Strength Indicator (RSSI) signal is available at U3101, pin 5, which has a dynamic
range of 70 dB. The RSSI signal is interpreted by the µP (U0101, pin 63) and is available at
accessory connector J0501-15.

3.0

UHF Band 2 (450-512/520 MHz) 25-40W LDMOS Transmitter
Power Amplifier (PA) 40W
The radio’s 40W PA is a three-stage amplifier used to amplify the output from the VCOBIC to the
radio transmit level. All three stages utilize LDMOS technology. The gain of the first stage (U5401) is
adjustable, controlled by pin 4 of PCIC (U5501). It is followed by an LDMOS stage (Q5421) and
LDMOS final stage (Q5441).

Devices U5401, Q5421 and Q5441 are surface mounted. A pressure pad between the board and
the radio’s cover provides good thermal contact between the devices and the chassis.

3.1

First Power Controlled Stage
The first stage (U5401) is a 20 dB gain integrated circuit containing two LDMOS FET amplifier
stages. It amplifies the RF signal from the VCO (TXINJ). The output power of stage U5401 is

6881091C63-A

Chapter 13: 2-4

UHF Band 2 (450-512/520 MHz) 25-40W LDMOS Transmitter Power Amplifier (PA) 40W

controlled by a DC voltage applied to pin 1 from Q5473. The control voltage simultaneously varies
the bias of two FET stages within U5401. This biasing point determines the overall gain of U5401
and therefore its output drive level to Q5421, which in turn controls the output power of the PA.
Switch S5440 is a pressure pad with a conductive strip which connects two conductive areas on the
board when the radio's cover is properly screwed to the chassis. When the cover is removed, S5440
opens and cuts the supply voltage to Q5473 thus disabling control voltage to U5401. This prevents
transmitter key up while the devices do not have proper thermal contact to the chassis.

3.2

Power Controlled Driver Stage
The next stage is an LDMOS device (Q5421) providing a gain of 12 dB. This device requires a
positive gate bias and a quiescent current flow for proper operation. The bias is set during transmit
mode by U5501-24 and fed to the gate of Q5421 via the resistive network R5480, R5408, R5415
and R5416.

3.3

Final Stage
The final stage is an LDMOS MRF1570 device Q5441. It provides a gain of 11 dB. It integrates two
MRF1535 die inside. These two die are being run in parallel. The output of each of the device (die)
inside are combined to constitute the total output power. This device also requires a positive gate
bias and a quiescent current flow for proper operation. The voltage of the line MOSBIAS_2 and
MOSBIAS_3 are set in transmit mode by the ASFIC and fed to the gate of Q5441 via two resistive
networks R5631, R5634, R5485, R5486 and R5632, R5635, R5481, R5489. These bias voltages
are tuned in the factory. If the transistor is replaced, the bias voltage must be tuned using the Global
Tuner. Care must be taken not to damage the device by exceeding the maximum allowed bias
voltage. The device’s drain current is drawn directly from the radio’s DC supply voltage input,
PASUPVLTG, via L5421, L5437 and L5436, L5438. A matching network consisting of C5440-45,
C5466-67, C5476-77, C5487, C5491, C5455-56, C5449-50, C5465, C5468 and striplines
transforms the impedance to 50 ohms and feeds the directional coupler.

3.4

Directional Coupler
The directional coupler is a microstrip printed circuit, which couples a small amount of the forward
power delivered by Q5441. The coupled signal is rectified by D5451. The DC voltage is proportional
to the RF output power and feeds the RFIN port of the PCIC (U5501 pin 1). The PCIC controls the
gain of stage U5401 as necessary to hold this voltage constant, thus ensuring the forward power out
of the radio to be held to a constant value.

3.5

Antenna Switch
The antenna switch consists of two PIN diodes, D5471 and D5472. In the receive mode, both diodes
are off. Signals applied at the antenna jack J5401 are routed, via the harmonic filter, through
network L5472, C5474 and C5475, to the receiver input. In the transmit mode, K9V1 turns on
Q5471 which enables current sink Q5472, set to 96 mA by R5512 and VR5471. This completes a
DC path from PASUPVLTG, through L5437, D5471, L5472, D5472, L5473, R5496 and the current
sink to ground. Both diodes are forward biased into conduction. The transmitter RF from the
directional coupler is routed via D5471 to the harmonic filter and antenna jack. D5472 also
conducts, shunting RF power and preventing it from reaching the receiver port (RXIN). L5472 is
selected to appear as a broadband lambda/4 wave transmission line, making the short circuit
presented by D5472 appear as an open circuit at the junction of D5472 and the receiver path.

Chapter 13: 2-5

Harmonic Filter
Components L5491-L5493 and L5472, C5448, C5494, C5496 and C5498 form a Butterworth lowpass filter to attenuate harmonic energy of the transmitter to specifications level. R5491 is used to
drain electrostatic charge that might otherwise build up on the antenna. The harmonic filter also
prevents high level RF signals above the receiver passband from reaching the receiver circuits,
improving spurious response rejection.

3.7

Power Control
The transmitter uses the power control IC (PCIC, U5501) to control the power output of the radio. A
portion of the forward RF power from the transmitter is sampled by the bi-directional coupler and
rectified to provide a DC voltage to the RFIN port of the PCIC (pin 1) that is proportional to the
sampled RF power.
The ASFIC (U0221) has internal digital-to-analog converters (DACs) which provide a reference
voltage of the control loop to the PCIC via R5483. The reference voltage level is programmable
through the SPI line of the PCIC. This reference voltage is proportional to the desired power setting
of the transmitter, and is factory programmed at several points across the frequency range of the
transmitter to offset frequency response variations of the transmitter’s power detector circuit.
The PCIC provides a DC output voltage at pin 4 (INT) which sets the drain current of the first
(U5401). This adjusts the transmitter power output to the intended value. Variations in forward
transmitter power cause the DC voltage at pin 1 to change, and the PCIC adjusts the control voltage
above or below its nominal value to raise or lower output power.
Capacitors C5502-4, in conjunction with resistors and integrators within the PCIC, control the
transmitter power rise (key-up) and power decay (de-key) characteristic to minimize splatter into
adjacent channels.
U5502 is a temperature-sensing device, which monitors the circuit board temperature in the vicinity
of the transmitter driver and final devices, and provides a DC voltage to the PCIC (TEMP, pin 30)
proportional to temperature. If the DC voltage produced exceeds the set threshold in the PCIC, the
transmitter output power will be reduced so as to decrease the transmitter temperature.

UHF Band 2 (450-512/520 MHz) 25-40W LDMOS Frequency
Synthesis
The synthesizer subsystem shown in Figure 13-3, consists of the reference oscillator (Y5261 or
Y5262), the Low Voltage Fractional-N synthesizer (LVFRAC-N, U5201), and the Voltage Controlled
Oscillator (VCO).

4.1

Reference Oscillator
The reference oscillator (Y5262) contains a temperature compensated crystal oscillator with a
frequency of 16.8 MHz. An analog-to-digital (A/D) converter internal to U5201 (LVFRAC-N) and
controlled by the µP via serial interface (SRL) sets the voltage at the warp output of U5201, pin 25 to
set the frequency of the oscillator. The output of the oscillator (Y5262, pin 3) is applied to pin 23
(XTAL1) of U5201 via an RC series combination.

6881091C63-A

Chapter 13: 2-6

UHF Band 2 (450-512/520 MHz) 25-40W LDMOS Frequency Synthesis

In applications where less frequency stability is required, the oscillator inside U5201 is used along
with external crystal Y5261, varactor diode D5261, C5261, C5262, and R5262. In this case, Y5262,
R5263, C5235 and C5251 are not used. When Y5262 is used, Y5261, D5261, C5261, C5262 and
R5262 are not used, and C5263 is increased to 0.1 uF.

4.2

Fractional-N Synthesizer
The LVFRAC-N synthesizer IC (U5201) consists of a pre-scaler, programmable loop divider, control
divider logic, phase detector, charge pump, A/D converter for low frequency digital modulation,
balanced attenuator used to balance high frequency analog modulation and low frequency digital
modulation, 13 V positive voltage multiplier, serial interface for control, and a super filter for the
regulated 5 volts.
A voltage of 5 V applied to the super filter input (U5201, pin 30) supplies an output voltage of 4.5
Vdc (VSF) at pin 28. It supplies the VCO, VCO modulation bias circuit (via R5322), and synthesizer
charge pump resistor network (R5251, R5252). The synthesizer supply voltage is provided by 5 V
regulator, U5211.
To generate a high voltage to supply the phase detector (charge pump) output stage at pin VCP
(U5701-32), a voltage of 13 Vdc is generated by the positive voltage multiplier circuit (D5201,
C5202, and C5203). This voltage multiplier is basically a diode capacitor network driven by two
signals (1.05 MHz) 180 degrees out of phase (U5201, pins 14 and 15).

The serial interface (SRL) is connected to the µP via data line DATA (U5201-7), clock line CLK
(U5201-8), and chip enable line CSX (U5201-9).

4.3

Voltage Controlled Oscillator (VCO)
The voltage controlled oscillator (VCO), shown in Figure 13-4, consists of a VCO buffer IC
(VCOBIC, U5301), TX and RX tank circuits, external RX buffer stages, and modulation circuits.
The VCOBIC together with Fractional-N synthesizer (U5201) generates the required frequencies in
both transmit and receive modes. The TRB line (U5301, pin 19) determines which tank circuits and
internal buffers are to be enabled. A high level on TRB enables TX tank and TX output (pin 10), and
a low enables RX tank and RX output (pin 8). A sample of the signal from the enabled output is
routed from U5301, pin 12 (PRESC_OUT), via a low-pass filter of U5201, pin 32 (PREIN).
A steering line voltage (VCTRL) between 3.0 V and 10.0 V at varactor diode CR5311 tunes the full
TX frequency range (TXINJ) from 450 MHz to 512 (or 520) MHz, and at varactor diodes CR5301,
CR5302, and CR5303 tunes the full RX frequency range (RXINJ) from 405 MHz to 467 MHz. The
tank circuits uses the Hartley configuration for wider bandwidth. For the RX tank circuit, external
transistor Q5301 is used in conjunction with the internal transistor for better side-band noise.

The external RX buffers (Q5332) are enabled by a high at U5201, pin 3 (AUX4) via transistor switch
Q5333. In TX mode, the modulation signal (VCOMOD) from the LVFRAC-N synthesizer IC (U5201,
pin 41) is applied to the modulation circuits CR5321, R5321, R5322, and C5324. These modulate
the TX VCO frequency via coupling capacitor C5321. Varactor CR5321 is biased for linearity from
the VSF.

4.4

Synthesizer Operation
The synthesizer consists of a low voltage FRAC-N (LVFRACN) IC, reference oscillator (crystal
oscillator with temperature compensation), charge pump circuits, loop filter circuits, and DC supply.
The output signal (PRESC_OUT) of the VCOBIC (U5301, pin12) is fed to U5201, pin 32 (PREIN) via
a low-pass filter (C5229,L5225,and C5226) which attenuates harmonics and provides correct level
to close the synthesizer loop.
The pre-scaler in the synthesizer (U5201) is a dual modulus pre-scaler with selectable divider ratios.
The divider ratio of the pre-scaler is controlled by the loop divider, which in turn receives its inputs
via the SRL. The output of the pre-scaler is applied to the loop divider. The output of the loop divider
is connected to the phase detector, which compares the loop divider’s output signal with the
reference signal. The reference signal is generated by dividing down the signal of the reference
oscillator (Y5261 or Y5262).
The output signal of the phase detector is a pulsed DC signal routed to the charge pump. The
charge pump outputs a current at U5201, pin 43 (IOUT). The loop filter (consisting of R5221-R5223,
C5221-C5225, and L5221) transforms this current into a voltage that is applied to varactor diodes
CR5311 for transmit, CR5301, CR5302 and CR5303 for receive and alters the output frequency of
the VCO. The current can be set to a value fixed in the LVFRAC-N IC or to a value determined by
the currents flowing into BIAS 1 (U5201-40) or BIAS 2 (U5201-39). The currents are set by the value
of R5251 or R5252 respectively. The selection of the three different bias sources is done by
software programming.
To reduce synthesizer lock time, when new frequency data has been loaded into the synthesizer, the
magnitude of the loop current is increased by enabling the IADAPT (U5201-45) for a certain
software programmable time (Adapt Mode). The adapt mode timer is started by a low to high
transition of the CSX line. When the synthesizer is within the lock range, the current is determined
only by the resistors connected to BIAS 1, BIAS 2, or the internal current source. A settled
synthesizer loop is indicated by a high level of signal LOCK (U5201-4) which is routed to one of the
µP’s ADCs input U101-56. From the voltage the µP determines whether LOCK is active.
To modulate the PLL, the two-spot modulation method is utilized via pin 10 (MODIN) on U5201. The
audio signal is applied to both the A/D converter (low frequency path) and the balanced attenuator
(high frequency path). The A/D converter converts the low frequency analog modulating signal into a
digital code which is applied to the loop divider, thereby causing the carrier to deviate. The balance
attenuator is used to adjust the VCO’s deviation sensitivity to high frequency modulating signals.
The output of the balance attenuator is present at the MODOUT port (U5201-41) and connected to
the VCO modulation diode CR5321 via R5321 and C5325.
