Intrinsically Safe Radio Information

2.1

FMRC Approved Equipment
Anyone intending to use a radio in a location where hazardous concentrations of flammable material
exist (hazardous atmosphere) is advised to become familiar with the subject of intrinsic safety and
with the National Electric Code NFPA 70 (National Fire Protection Association) Article 500 (hazardous
[classified] locations).
An Approval Guide, issued by Factory Mutual Research Corporation (FMRC), lists manufacturers and
the products approved by FMRC for use in such locations. FMRC has also issued a voluntary
approval standard for repair service (“Class Number 3605”).
FMRC Approval labels are attached to the radio to identify the unit as being FM Approved for
specified hazardous atmospheres. This label specifies the hazardous Class/Division/Group along
with the part number of the battery that must be used. Depending on the design of the portable unit,
this FM label can be found on the back of the radio housing or the bottom of the radio housing.Their
Approval mark is shown below.
FM
APPROVED

!

WARNING: Do not operate radio communications equipment in a hazardous atmosphere
unless it is a type especially qualified (e.g. FMRC Approved) for such use. An explosion or
fire may result.
WARNING: Do not operate the FMRC Approved Product in a hazardous atmosphere if it has
been physically damaged (e.g. cracked housing). An explosion or fire may result.
WARNING: Do not replace or charge batteries in a hazardous atmosphere. Contact sparking
may occur while installing or removing batteries and cause an explosion or fire.
WARNING: Do not replace or change accessories in a hazardous atmosphere. Contact
sparking may occur while installing or removing accessories and cause an explosion or fire.
WARNING: Do not operate the FMRC Approved Product unit in a hazardous location with the
accessory contacts exposed. Keep the connector cover in place when accessories are not
used.
WARNING: Turn radio off before removing or installing a battery or accessory.
WARNING: Do not disassemble the FMRC Approved Product unit in any way that exposes
the internal electrical circuits of the unit.
Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability
and FM Approval labeling. Radios will not be “upgraded” to this capability and labeled in the field.
A modification changes the unit’s hardware from its original design configuration. Modifications can
only be done by the original product manufacturer at one of its FMRC audited manufacturing facilities.

!

WARNING: Failure to use an FMRC Approved Product unit with an FMRC Approved battery
or FMRC Approved accessories specifically approved for that product may result in the dangerously unsafe condition of an unapproved radio combination being used in a hazardous
location.
Unauthorized or incorrect modification of an FMRC Approved Product unit will negate the Approval
rating of the product.

2-2

Intrinsically Safe Radio Information

2.2

Repair of FMRC Approved Products
REPAIRS FOR MOTOROLA FMRC APPROVED PRODUCTS ARE THE RESPONSIBILITY OF THE
USER.
You should not repair or relabel any Motorola manufactured communication equipment bearing the
FMRC Approval label (“FMRC Approved Product”) unless you are familiar with the current FMRC
Approval standard for repairs and service (“Class Number 3605”).
You may want to consider using a repair facility that operates under 3605 repair service approval.

!

WARNING: Incorrect repair or relabeling of any FMRC Approved Product unit could
adversely affect the Approval rating of the unit.
WARNING: Use of a radio that is not intrinsically safe in a hazardous atmosphere could
result in serious injury or death.
FMRC’s Approval Standard Class Number 3605 is subject to change at any time without notice to
you, so you may want to obtain a current copy of 3605 from FMRC. Per the December, 1994
publication of 3605, some key definitions and service requirements are as follows:

2.2.1

Repair
A repair constitutes something done internally to the unit that would bring it back to its original
condition Approved by FMRC. A repair should be done in an FMRC Approved facility.
Items not considered as repairs are those in which an action is performed on a unit which does not
require the outer casing of the unit to be opened in a manner which exposes the internal electrical

This chapter provides a detailed theory of operation for the radio components. Schematic diagrams
for the circuits described in the following paragraphs are located in Figures 5-1 through 5-34.

3.2

Radio Power Distribution
A block diagram of the DC power distribution throughout the radio board is shown in Figure 3-1. Four
voltage regulators are used as follows:

The 7.5 V battery supplies radio power (UNSWB) directly to the electronic on/off control circuit, audio
power amplifier, 3.3 V Li-Ion regulator U410, transmitter PA driver and PA Final stage, the Power
Control IC, and the low battery detect circuit.
When the radio on/off/volume control is turned on, the switched battery voltage SWB+ from Q400 is
applied to the various regulators, antenna switch, the 20-pin accessories connector J403, the 40-pin
keypad/option board connector J400, and the transmit LED. The Vddd source from digital 3.3V
regulator U400 supplies operating power to the microprocessor, EEPROM, RAM and Flash ROM IC's.
The Vdda analog 3.3 V regulator (U3201 in 200 MHz models, U203 in 700 MHz models) provides
operating voltage for the ASFICcmp, VCOBIC, synthesizer IC. The 5 V regulator (U3711 in 200, U202
in 700) also powers the synthesizer IC as well as the receiver front end and IF circuitry, the RX and
TX (700 MHz only) VCO buffers, and the opamp audio gain stage. Some stages are supplied only
during receive by 5R, switched by Q3721 (200) or Q201 (700 MHz). Regulator voltage routing is
configurable by jumper placement. All models are configured with R401 and R405 placed, and R4024 not placed.
At power up, Q400 is initially turned on by the path through Q403, CR440, and Q405. When C480 has
charged, this path is disabled, and Q400 is maintained on via a logic high ASFICcmp U404 pin 37, via
CR440 and Q405.
The radio turns off when either of the two following conditions occur:
•
•

Radio on/off/volume control is turned off.
Low battery condition is detected.

If a low battery level or loss of battery voltage is detected by the microprocessor pin 67 through either
of the above conditions, the radio personality data is stored to EEPROM prior to turning off. At this
point U404-37 goes low, turning off Q400.

Keypad/PassPort Option Board
The keypad/PassPort Option Board block diagram is shown in Figure 3-2. The keypad circuitry is
contained on the PassPort Option Board.
Two resistive voltage divider networks form a row and column matrix. Pressing any button
simultaneously grounds a tap on the row and column voltage dividers which outputs a unique row
voltage and column voltage level for that button location. The row and column voltages are applied to
two A/D inputs of the microprocessor (U409 pins 60 and 61). The keypad column voltage is also
applied to a comparator whose threshold is set to produce an interrupt signal (KEY_INT) whenever
any key is pressed. The microprocessor then samples the voltage levels at the keypad row and
keypad column A/D inputs and makes a comparison with a map table to identify the key pressed.
Once the key is identified, a corresponding function is executed.
The LED_EN is set by the codeplug. When the value is set to low, the LED lights up during power up.
A high codeplug setting disables this feature.

Theory of Operation

Real Time Clock
Radios with displays support a real time clock (RTC) module for purposes of message time stamping
and time keeping. The RTC module resides in the microcontroller. The clock uses a back-up lithiumIon battery for operating power when the primary battery is removed.

3.4.3

Circuit Description
The RTC module circuit, shown in Figure 3-4, is powered by the MODB/VSTBY pin and PI6/PI7 from
the crystal oscillator circuit. A clock frequency of 38.4kHz from a crystal oscillator provides the
reference signal which is divided down to 1Hz in the processor.
As the RTC module is powered separately from the processor Vdd, the RTC is kept active through the
MODB/VSTBY pin which provides the lithium battery back-up power when the radio is switched off.
A MOSFET transistor (Q416) switches in the battery supply when Vdd is removed. Q416 also
provides isolation from BOOT_CTRL function. The 3.3V regulator charges the Lithium battery.

Audio/Signaling
The audio/signalling/filter/companding IC (ASFIC) and the audio power amplifier (Figure 3-3) form the
main components of the audio/signalling section of the controller board. Inputs include a 16.8 MHz
clock from the synthesizer, recovered audio and squelch, MCU control signals, and external or
internal microphones. Outputs include a microprocessor clock (CLK), modulator output to the
synthesizer, and amplified audio signals to an internal or external speaker.
An additional opamp gain stage (U2000 in 200 MHz models, or U851 in 700 MHz models, and
associated circuitry) is included to increase the receiver audio level from the IFIC into the ASFIC
audio processing IC. This is necessitated because of the low voice deviation levels encountered in
trunked systems operating at 12.5 kHz channel spacing.

The 200 MHz PA consists of two LDMOS devices:

•

C65 LDMOS driver IC (U3501)
MRF1517 LDMOS PA final (Q3501)

The C65 LDMOS driver (U101) provides 2-stage amplification using a supply voltage of 7.5V. The
amplifier is capable of supplying an output power of 0.5W (U3501 pins 6 & 7) with an input signal of
2mW (+3dBm) at U3501 pin 16. The current drain is typically 180mA while operating in the frequency
range of 216-222 MHz.
The LDMOS PA is capable of supplying an output power of up to 6W with an input signal of 0.5W. The
current drain is typically 1400 mA while operating in the frequency range of 216-222 MHz. The power
output can be varied by changing the bias voltage.

3-6

3.5.2

Theory of Operation

Antenna Switch
The antenna switch circuit consists of two pin diodes (D3521 and D3551), a pi network (C3531,
L3551, C3550), and two current limiting resistors (R3572-3). In the transmit mode, pin 32 of PCIC
U3502 goes high which applies a B+ source to the antenna switch circuit to bias the diodes "on". The
shunt diode (D3551) shorts out the receiver port and the pi network. This operates as a quarter wave
transmission line to transform the low impedance of the shunt diode to a high impedance at the input
of the harmonic filter. In the receive mode, the diodes are both off, creating a low attenuation path
between the antenna and receiver ports via L3551.

3.5.3

Harmonic Filter
The harmonic filter consists of components C3531-2, C3535-6, and L3531-2. The harmonic filter is a
modified Zolotarev design optimized for efficiency of the power module. This type of filter has the
advantage that it can give a greater attenuation in the stop-band for a given ripple level. The harmonic
filter insertion loss is typically less than 1.2 dB.

3.5.4

Antenna Matching Network
Because the 200 MHz antenna is a 50-ohm design, no matching circuitry is required between the
harmonic filter output and the 50-ohm SMA-style antenna connector (J3501).

3.5.5

Power Control Integrated Circuit (PCIC)
The transmitter uses the PCIC (U3502) to regulate the power output of the radio. The current drain of
the final device Q3501 is measured as the voltage drop across series resistor R3519. This voltage is
then fed back to the automatic level control (ALC) within the PCIC to regulate the output power of the
transmitter. The PCIC contains internal digital to analog converters (DACs) that provide a
programmable control loop reference voltage. The PCIC internal resistors, integrators, and external
capacitors (C3562-3 and C3565) control the transmitter rise and fall times to reduce the power
splatter into adjacent channels.

3.5.6

Temperature Cut Back Circuit
Temperature sensor U3503 and associated components are part of a temperature cutback circuit.
This circuit senses the printed circuit board temperature around the transmitter circuits and outputs a
DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold of the PCIC, the
transmitter output power decreases to reduce the transmitter temperature.

3.6

200 MHz Receiver
The 200 MHz receiver design is separated into two blocks, the front end and the back end. The overall
block diagram of the receiver is shown in Figure 3-6. Detailed descriptions of these stages are
contained in the paragraphs that follow.

3.6.1

Receiver Front-End
The received signal from the antenna is routed through the harmonic filter and antenna switch and
applied to the antenna filter, consisting of L3320-22 and C3340-47. This fixed-tuned 3-pole bandpass
filter is configured to provide steeper attenuation above the passband for improved spurious rejection
when high-side first injection is used. The output of this filter is coupled to RF amplifier Q3302. Diode
CR3303 protects the RF amplifier by limiting excessive RF levels. Current mirror Q3303 maintains
constant current operation of the RF amp vs. device and temperature variations, for optimum dynamic
range and noise figure.
The output of the RF amplifier is applied to the RF amp filter comprised of L3323-4, L3341, C3352-7
and C3359, also a fixed-tuned 3-pole bandpass filter configured to provide steeper high-side
attenuation. Both the antenna filter and RF amp filter have 3 dB bandwidths of 22 MHz and utilize 2%
inductors and 1% capacitors for accurate and repeatable passband response.
The output of the RF amp filter is connected to the passive double-balanced mixer consisting of
components T3301, T3302, and CR3301. High-side injection from the frequency synthesizer is lowpass filtered by C3373-6, C3381, and L3327-8 to remove second harmonic energy which may
degrade half-IF spurious rejection performance, and applied to T3302 at a level of +5 dBm.
The IF output from T3301 is applied to a diplexer (L3325, C3361, R3332, L3281) which matches the
44.85 MHz IF signal to the crystal filter and terminates the mixer into 50O at all other frequencies.

3.6.2

Receiver Back-End
The receiver back end is a dual conversion design. High IF selectivity is provided by FL3201, a 4-pole
fundamental mode 44.85 MHz crystal filter with a 3 dB bandwidth of 7.5 kHz. The output is fed to IF
amplifier stage Q3200, whose input impedance is adjusted using feedback to provide a proper
terminating impedance for the filter. The output of Q3200 is applied to the input of the receiver IFIC
U3101. Diode CR3200 prevents overdriving the IFIC.

3-8

Theory of Operation

The IFIC is a low-voltage monolithic FM IF system incorporating a mixer/oscillator, two limiting IF
amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), voltage
regulator and audio and RSSI op amps. The second LO frequency is determined by Y3200.
Additional IF selectivity is provided by two ceramic filters, FL3204 (between the second mixer and IF
amp) and FL3206 (between the IF amp and the limiter input). FL3204 is a 4 element filter with a BW6
= 12 kHz. FL3206 is a 6 element filter with a BW6 = 9 kHz. These bandwidths are optimum for 12.5
kHz channel spacing systems. Ceramic resonator Y3102 provides phase vs. frequency characteristic
required by the quadrature detector, with 90 degree phase shift occurring at 455 kHz. Buffer Q3211
provides a lower driving impedance from the limiter to the resonator, improving the IF waveform and
lowering distortion.

3.7.1

200 MHz Frequency Generation System
Overview
The frequency generation system, shown in Figure 3-7, is composed of two circuit blocks, the
Fractional-N synthesizer IC U3701, the VCO/Buffer IC U3801, and associated circuitry. Figure 2-8
shows the peripheral interconnect and support circuitry used in the synthesizer block, and Figure 2-9
details the internal circuitry of the VCOBIC and its interconnections to the surrounding components.
Refer to the schematic to identify reference designators.
The Fractional-N synthesizer is powered by regulated 5V and 3.3V provided by U3711 and U3201
respectively. 5V is applied to U3701 pins 13 and 30, and 3.3V is applied to pins 5, 20, 34 and 36. The
synthesizer in turn generates a super-filtered 4.5V supply (VSF, from pin 28) to power U3801. In
addition to the VCO, the synthesizer also interfaces with the logic and ASFIC circuits. Programming
for the synthesizer is accomplished through the microprocessor data, clock, and chip select lines
(U409 pins 100, 1 and 2 respectively). A logic high (3.3V) from U3701 pin 4 indicates to the
microprocessor that the synthesizer is locked.

Transmit modulation from the ASFICcmp is applied to U3701 pin 10. An electronic attenuator in the
ASFICcmp adjusts overall transmitter deviation by varying the audio level applied to the synthesizer
IC. Internally the audio is digitized by the Fractional-N and applied to the loop divider to provide the
low-port modulation. The audio is also routed through an internal attenuator for modulation balancing
purposes and is available at U3701 pin 41 (VCO_MOD). This audio signal is routed to the VCO's
modulator.

Theory of Operation

3.7.2

3-9

Fractional-N Synthesizer
The Fractional-N synthesizer, shown in Figure 3-8, uses a 16.8 MHz reference oscillator (Y3762) to
provide a high stability reference for the system. Stability is better than 2.5 ppm over temperatures of
-30 to 60 °C. Electronic frequency adjustment is achieved by an internal DAC which provides a
frequency adjustment voltage from U3701 pin 25 to the reference oscillator module. The synthesizer
IC U3701 further divides the 16.8 MHz signal (applied to U3701 pin 23) to 2.1 MHz, 2.225 MHz, or 2.4
MHz for use as reference frequencies. It also provides 16.8 MHz at U3701 pin 19 for use by the
ASFIC. A loop filter (C3723-4, R3722-3) removes noise and spurs from the steering voltage applied to
the VCO varactors, with additional filtering located in the VCO circuit.
To achieve fast locking for the synthesizer, an internal adapt charge pump provides higher current at
U3701 pin 45 to quickly force the synthesizer within lock range. The required frequency is then locked
by normal mode charge pump at pin 43. Both the normal and adapt charge pumps get their supply
from the capacitive voltage multiplier made up of C3701-4 and D3701-2. Two 3.3V square waves from
U3701 pins 14-15 provide the drive signals for the voltage multiplier, which generates 13.3V at U3701
pin 47. This voltage is filtered by C3705-6 and C3714.
One of the auxiliary outputs of the synthesizer IC (pin 48) controls transistor switch Q3721 which
outputs a T5 voltage source during transmit and R5 during receive.

Voltage Controlled Oscillator (VCO)
The VCOBIC (U3801), shown in Figure 3-9, in conjunction with the Fractional-N synthesizer (U3701)
generates RF in both the receive and the transmit modes of operation. The TRB line (U3801 pin 19)
determines which oscillator and buffer are enabled. A sample of the RF signal from the enabled
oscillator is routed from U3801 pin 12 through a low pass filter, to the prescaler input of the
synthesizer IC (U3701 pin 32). After frequency comparison in the synthesizer, a resultant DC control
voltage is used to steer the VCO frequency. When the PLL is locked on frequency, this voltage can

3-10

Theory of Operation

vary between 3.5V and 9.5V. An additional loop filter pole (R3828, C3831 and C3843, further
attenuate noise and spurs on the steering line voltage.
In the receive mode, the TRB line (U3801 pin 19) is low. This activates the receive VCO and the
receive buffer of U3801, which operate within the range of 261.85 to 266.85 MHz. The VCO frequency
is determined by tank inductor L3822, C3830 and varactor D3821. The buffered RF signal at U3801
pin 8 is further amplified by Q3802 and applied as RX_INJ to the low-pass injection filter in the
receiver front end circuit.
In the transmit mode, U3801-19 is driven high (4.4V) by U3701 pin 2, enabling the transmit VCO and
buffer. The 217-222 MHz RF signal from U3801 pin 10 is applied as TX_INJ to the input of the
transmitter driver IC (U3501 pin 16) via a resistive attenuator pad. TX VCO frequency is determined
by L3833, C3870 and varactor D3831. Audio from the synthesizer IC is applied as VCO_MOD to
varactor D3832 which modulates the transmit VCO.

amplifier is capable of supplying an output power of 0.5W (U101 pins 6 & 7) with an input signal of
2mW (+3dBm) at U101 pin 16. The current drain is typically 180mA while operating in the frequency
range of 746-794 MHz.
The LDMOS PA final was designed to supply an output power of 2.75W with an input signal of 0.3W.
The PA current drain is typically 1050 mA while operating in the frequency range of 746-794 MHz.

C109 and L103), and three current limiting resistors (R101-3). In the transmit mode, pin 32 of PCIC
U102 goes high which applies a B+ source to the antenna switch circuit to bias the diodes "on". The
shunt diode (CR102) shorts out the receiver port and the pi network. This operates as a quarter wave
transmission line to transform the low impedance of the shunt diode to a high impedance at the input
of the harmonic filter. In the receive mode, the diodes are both off, creating a low attenuation path
between the antenna and receiver ports via L103.

Theory of Operation

Harmonic Filter
The harmonic filter is a modified Zolotarev design optimized for efficiency of the PA. It consists of a
combination of lumped components (C102-7, L101-2) and microstrip elements. This type of filter has
the advantage that it can give a greater attenuation in the stop-band for a given ripple level. The
design was optimized to meet critical attenuation requirements for the second harmonic in the 15591610 MHz GNSS band. The harmonic filter insertion loss is typically less than 1 dB.

3.8.4

Antenna Matching Network
Because the 700 MHz antenna is a 50-ohm design, no matching circuitry is required between the
harmonic filter output and the 50-ohm SMA-style antenna connector (J101).

3.8.5

Power Control Integrated Circuit (PCIC)
The transmitter uses the PCIC (U102) to regulate the power output of the radio. The current to the
final device Q101 is supplied through resistor R116, that provides a voltage drop proportional to the
final device current drain. This voltage is then fed back to the automatic level control (ALC) within the
PCIC to regulate the output power of the transmitter. The PCIC contains internal digital to analog
converters (DACs) that provide a programmable control loop reference voltage. The PCIC internal
resistors, integrators, and external capacitors (C142, C144 and C146) control the transmitter rise and
fall times to reduce the power splatter into adjacent channels.

3.8.6

Temperature Cut Back Circuit
Temperature sensor U103 and associated components are part of a temperature cutback circuit. This
circuit senses the printed circuit board temperature around the transmitter circuits and outputs a DC
voltage to the PCIC. If the DC voltage produced exceeds the set threshold of the PCIC, the transmitter
output power decreases to reduce the transmitter temperature.

3.9

700 MHz Receiver
The 700 MHz receiver design is separated into two blocks, the front end and the back end. The overall
block diagram of the receiver is shown in Figure 3-11. Detailed descriptions of these stages are

3.9.1

Receiver Front-End
The received signal from the antenna is routed through the harmonic filter and antenna switch and
applied to the antenna filter FL300. This is a fixed-tuned 3-pole ceramic bandpass filter with a
passband of 744 MHz to 766 MHz and an insertion loss of 2.6 dB. The output of this filter is coupled
to RF amplifier Q301. Diode CR300 protects the RF amplifier by limiting excessive RF levels.
The output of the RF amplifier is applied to the RF amp filter FL301, identical to FL300. The output of
FL301 is connected to the passive double-balanced mixer consisting of components T301, T302, and
CR301. High-side injection from the frequency synthesizer is band-pass filtered by C317-324 and
L305-6 to remove second harmonic energy which may degrade half-IF spurious rejection
performance, and applied to T302 at a level of +8 dBm.
The IF output from T301 is applied to a diplexer (L303-4, C313-5 and R305) which matches the 73.35
MHz IF signal to the crystal filter and terminates the mixer into 50O at all other frequencies.

3.9.2

Receiver Back-End
The receiver back end is a dual conversion design. The 73.35 MHz high IF consists of 2-pole crystal
filter FL350, IF amp Q350, 2-pole crystal filter FL351 and IF amp Q351. Each crystal filter has a 3 dB
bandwidth of 9.0 kHz and a maximum insertion loss of 2 dB. The output of Q351 is applied to the
input of the receiver IFIC U350. Diode D350 prevents overdriving the IFIC.
The IFIC is a low-voltage monolithic FM IF system incorporating a mixer/oscillator, two limiting IF
amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), voltage
regulator and audio and RSSI op amps. The second LO frequency is determined by Y350. Additional
IF selectivity is provided by two ceramic filters, FL352 (between the second mixer and IF amp) and
FL353 (between the IF amp and the limiter input). FL352 is a 6 element filter with a BW6 = 9 kHz.
FL353 is a 4 element filter with a BW6 = 12 kHz. These bandwidths are optimum for 12.5 kHz channel
spacing systems. Ceramic resonator Y351 provides phase vs. frequency characteristic required by
the quadrature detector, with 90 degree phase shift occurring at 455 kHz. Buffer Q352 provides a
lower driving impedance from the limiter to the resonator, improving the IF waveform and lowering
distortion.

3.10 700 MHz Frequency Generation System
3.10.1

Overview
The frequency generation system, shown in Figure 3-12, is composed of two circuit blocks, the
Fractional-N synthesizer IC U201, the VCO/Buffer IC U600, and associated circuitry. Figure 2-13
shows the peripheral interconnect and support circuitry used in the synthesizer block, and Figure 2-14

Figure 3-12. 700 MHz Frequency Generation System Block Diagram
The Fractional-N synthesizer is powered by regulated 5V and 3.3V provided by U202 and U203
respectively. 5V is applied to U201 pin 30, and 3.3V is applied to pins 5, 13, 20, 34 and 36. The
synthesizer in turn generates a super-filtered 4.5V supply (VSF, from pin 28) to power U600. In
addition to the VCO, the synthesizer also interfaces with the logic and ASFIC circuits. Programming
for the synthesizer is accomplished through the microprocessor data, clock, and chip select lines
(U409 pins 100, 1 and 2 respectively). A logic high (3.3V) from U201 pin 4 indicates to the
microprocessor that the synthesizer is locked.
Transmit modulation from the ASFICcmp is applied to U201 pin 10. An electronic attenuator in the
ASFICcmp adjusts overall transmitter deviation by varying the audio level applied to the synthesizer
IC. Internally the audio is digitized by the Fractional-N and applied to the loop divider to provide the
low-port modulation. The audio is also routed through an internal attenuator for modulation balancing
purposes and is available at U201 pin 41 (MODOUT). This audio signal is attenuated significantly by
R211-12, and superimposed on the steering line voltage by a capacitive voltage divider (C242 and
C245). This allows the same varactor used for TX VCO frequency steering to serve as the VCO's
modulator.

3.10.2

Fractional-N Synthesizer
The Fractional-N synthesizer, shown in Figure 3-13, uses a 16.8 MHz reference oscillator (Y200) to
provide a high stability reference for the system. Stability is better than 1.5 ppm over temperatures of
-30 to 60 °C. Electronic frequency adjustment is achieved by an internal DAC which provides a
frequency adjustment voltage from U201 pin 25 to the reference oscillator module. The synthesizer IC
U201 further divides the 16.8 MHz signal (applied to U201 pin 23) to 2.1 MHz, 2.225 MHz, or 2.4 MHz
for use as reference frequencies. It also provides 16.8 MHz at U201 pin 19 for use by the ASFIC. A
loop filter (C241, C243-5, R213-5) removes noise and spurs from the steering voltage applied to the
VCO varactors.

Figure 3-13. 700 MHz Synthesizer Block Diagram
To achieve fast locking for the synthesizer, an internal adapt charge pump provides higher current at
U201 pin 45 to quickly force the synthesizer within lock range. The required frequency is then locked
by normal mode charge pump at pin 43. Both the normal and adapt charge pumps get their supply
from the capacitive voltage multiplier made up of C211-14 and CR201-2. Two 3.3V square waves
from U201 pins 14-15 provide the drive signals for the voltage multiplier, which generates 12.8V at
U201 pin 47. This voltage is filtered by C223-5.
One of the auxiliary outputs of the synthesizer IC (pin 48) controls transistor switch Q201 which
outputs a switched R5 voltage source, present during receive mode. Another auxiliary output (pin 2)
controls transistor switch Q202 which outputs a switched AU3-5V source for TX buffer stage Q601 in
the VCO circuit.

3.10.3

Voltage Controlled Oscillator (VCO)
The VCOBIC (U600), shown in Figure 3-14, in conjunction with the Fractional-N synthesizer (U201)
generates RF in both the receive and the transmit modes of operation. The TRB line (U600 pin 19)
determines which oscillator and buffer are enabled, and is controlled by the AUX4 signal from the
synthesizer (U201 pin 3). Transistor Q603 level-shifts the synthesizer's 3.3V logic level to the 5V
operating level of the VCOBIC. A sample of the RF signal from the enabled oscillator is routed from
U600 pin 12 through a low pass filter (L203, C234 in the synthesizer circuit), to the prescaler input of
the synthesizer IC (U201 pin 32). After frequency comparison in the synthesizer, a resultant DC
control voltage is used to steer the VCO frequency. When the PLL is locked on frequency, this voltage
can vary between 2 to 9 volts in the RX mode or 3 to 11 volts in the TX mode.
In the receive mode, the TRB line (U600 pin 19) is low. This activates the receive VCO and the
receive buffer of U600, which operate within the range of 819.35 to 837.35 MHz. The RX VCO
frequency is determined by ceramic tank resonator FL600, varactors CR600 and CR601, and
associated components. Feedback to maintain oscillation is provided by divider C607-8 and
associated components. The buffered RF signal at U600 pin 8 is further amplified by Q600 and
applied as RX_LO to the low-pass injection filter in the receiver front end circuit.

3-16

Theory of Operation

In the transmit mode, Q603 is off and U600-19 is pulled high to 5V by R655, enabling the transmit
VCO and buffer. The 746-794 MHz RF signal from U600 pin 10 is applied as TX_INJ to the input of
the transmitter driver IC (U101 pin 16). TX VCO frequency is determined by ceramic tank resonator
FL601, varactor CR603, and associated components. Audio modulation is superimposed on the
steering line voltage, allowing varactor CR603 to also function as the modulator.
When a high impedance is applied to U3801, pin19, the VCO is operating in battery saver mode. In
this case, both the receive and transmit oscillators as well as the receive transmit and prescaler buffer
are turned off.

3.11 Trunked Radio Systems
Trunked systems allow a large number of users to share a relatively small number of frequencies or
repeaters without interfering with each other. The airtime of all the repeaters in a trunked system is
pooled, which maximizes the amount of airtime available to any one radio and minimizes channel
congestion. A benefit of trunking is that the user is not required to monitor the system before
transmitting.

3.11.1

LTR® Trunked Systems
LTR is a transmission based trunking protocol developed by the E. F. Johnson Company for primarily
single site trunking applications. In transmission trunking, a repeater is used for only the duration of a
single transmission. Once a transmission is completed, that repeater becomes available to other
users.

3.11.2

PassPort® Trunked Systems
PassPort is an enhanced trunking protocol developed by Trident Microsystems that supports wide
area 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.
All 200 MHz and 700 MHz models feature PassPort Trunking operation, and the standard keypad
board is replaced with the PassPort Trunking Controller Board (PTCB). This board also provides
advanced voice storage features. Refer to Figure 3-2 for connector and signal routing from, to and
through the Radio, PTCB and Liquid Crystal Display (LCD) sub-systems.

3.11.2.1 Power Supplies
The radio supplies regulated Vdd of 3.3 VDC. This is used to power the Low Speed Data Filter and
Voice Storage circuits. The radio also supplies Switched Battery Voltage (SWB+). U612 regulates the
SWB+ to 3.3V which is applied to the PTCB microcontroller U601. A filtered voltage (Vdda) of Vdd/2
is developed by U603-4 and is used to supply a clean reference bias for the Low Speed Data filter and
Voice Storage circuits. U610 regulates the SWB+ voltage to 3.3V which is applied to the PTCB Voice
Storage IC, U611, as well.

3.11.2.2 Microcontroller (MCU)
PassPort Trunking operation is managed by the reprogrammable FLASH ROM based microcontroller
(U601). The MCU clock oscillator uses 7.9488 MHz crystal Y601 as a stable resonator. The PTCB
communicates with the main radio microcontroller by attaching to the same Serial Peripheral (SPI)
bus that passes though the PTCB to the LCD on the CLK, DATA, RDY, and MISO lines. The OPT_EN
line is strobed low only for communications with U601.
The MCU includes an on-chip Analog to Digital Converter (ADC). The received and filtered subaudible low speed trunking data waveform is applied to one of the ADC inputs. The software in the
MCU decodes and acts upon the trunking data.
The MCU includes a Digital to Analog Converter (DAC). As required, the MCU software generates
appropriate PassPort Low Speed Trunking Data waveforms. These are applied to the Low Speed
Data Filter and then to the radio transmitter modulation point. The amplitude of this waveform and the
resulting transmitted deviation is controlled by software.

3-18

Theory of Operation

3.11.2.3 Low Speed Data Filter
This analog circuitry is a 4 pole, 150 Hz cutoff low pass filter comprised of U603-1, U603-2 and
associated passive components. In receive mode, it removes noise and voice band signals leaving
only the low speed data waveform which is applied to the ADC input of the MCU. U608-4 isolates the
receive signal from the filter in transmit mode. When the radio is transmitting PassPort data, the MCU
DAC low speed data waveform is applied to the input of the filter which removes harmonics that would
interfere with voice and applies the resulting sub-audible data to the radio transmitter modulation
point.

3.11.2.4 Keyboard/PassPort Option Board Circuit
The keyboard/PassPort Option Board consists of a matrix of key switches and resistors as described
in section 3.3. U605-2 monitors the column voltage and applies an interrupt signal to the radio
microcontroller when any key is pressed.

3.11.2.5 BackLight Driver and LED's
The logic level signal from the radio microcontroller is translated via Q611 and applied to Q610 which
uses Switched Battery Voltage (SWB+) to operate the keypad backlight LED’s.

3.11.2.6 Voice Storage
The Voice Storage (VS) 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 PTCB hosts the Voice Storage circuitry. Voice Storage IC U611 provides all the required
functionality and is powered from the regulated 3.3 volts from U610. The µP controls U611 via SPI
bus lines CLK (U611-8), DATA (U611-10) and MISO (U611-11). To transfer data, the µP first selects
the U611 via line VS CS and U611 pin 9. Then the µP sends data through line DATA and receives
data through line MISO. Pin 2 (RAC) of U611 indicates the end of a message row by a low state for
12.5 ms and connects to µP pin 65. 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 from the ASFIC
CMP (U404) at pin 43, through switch U608-1 that is selected by the µP via ASFIC CMP pin 5 (DACR)
and then enters the voice storage IC U611 at pin 25. During playback, the stored audio emerges from
U611 at pin 20. To transmit the audio signal, it is fed through resistive divider R657 / R658, through
switch U608-3 and through line EXT MIC. When this path is selected, 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 U611 pin 20 is buffered by op-amp U605-1, through switch U608-2
and fed via 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. Switches U608-2 and U608-3 are controlled by the µP via ASFIC CMP pin 6
(DACG) and feed the stored audio only to the ASFIC CMP port UIO when it is programmed as input.

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.

4.3

Inspection
Check that the external surfaces of the radio are clean, and that all external controls and switches are
functional. It is not recommended to inspect the interior electronic circuitry.

4.3.1

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.
NOTE Internal surfaces should be cleaned only when the radio is disassembled for servicing or
repair.
The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild
dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit
boards and their components is isopropyl alcohol (70% by volume).

!

CAUTION: The effects of certain chemicals and their vapors can have harmful results on
certain plastics. Aerosol sprays, tuner cleaners, and other chemicals should be avoided.
1. Cleaning External Plastic Surfaces
The detergent-water solution should be applied sparingly with a stiff, non-metallic, short-bristled
brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should
be used to remove the solution and dry the radio. Make sure that no water remains entrapped
near the connectors, cracks, or crevices.
2. Cleaning Internal Circuit Boards and Components
Isopropyl alcohol may be applied 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.

4-2

Maintenance

NOTE Always use a fresh supply of alcohol and a clean container to prevent contamination by
dissolved material (from previous usage).

4.4

Safe Handling of CMOS and LDMOS
Complementary metal-oxide semiconductor (CMOS) and lateral diffusion metal oxide semiconductor
(LDMOS) devices are used in this family of radios. Their 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, special precautions must be taken to prevent device damage during
disassembly, troubleshooting, and repair.
Handling precautions are mandatory for the circuits and are especially important in low humidity
conditions. DO NOT attempt to disassemble the radio without first referring to the CMOS CAUTION
paragraph in the Disassembly and Reassembly section of the basic manual (See Chapter 3).

4.5

General Repair Procedures and Techniques
•

Parts Replacement and Substitution
When damaged parts are replaced, identical parts should be used. If the 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 Communications parts center listed in the “Piece
Parts” section of this manual (See Chapter 1).

•

Rigid Circuit Boards
The 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 unsoldering
components. The printed-through holes may interconnect multiple layers of the printed circuit.
Therefore, care should be exercised to avoid pulling the plated circuit out of the hole.

When soldering near the 20-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.

Flexible Circuits
The flexible circuits are made from a different material than the rigid boards and different
techniques must be used when soldering. Excessive prolonged heat on the flexible circuit can
damage the material. Avoid excessive heat and excessive bending.
For parts replacement, use the ST-1087 Temperature-Controlled Solder Station with a 600-700
degree tip, and use small diameter solder such as ST-633. The smaller size solder will melt faster
and require less heat to be applied to the circuit.
To replace a component on a flexible circuit:
•
•
•

grasp the edge of the flexible circuit with seizers (hemostats) near the part to be removed.
pull gently.
apply the tip of the soldering iron to the component connections while pulling with the
seizers.

Do not attempt to puddle out components. Prolonged application of heat may damage the
flexible circuit.

4-3

Chip Components
Use either the RLN-4062 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 700 degrees F. (370
degrees C), and adjust the airflow to a minimum setting. Airflow can vary due to component
density.
To remove a chip component:
• Use a hot-air hand piece and position the nozzle of the hand piece approximately 1/8” (0.3
cm) above the component to be removed.
• Begin applying the hot air. Once the solder reflows, remove the component using a pair of
tweezers.

•

• 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:
• Select the appropriate micro-tipped soldering iron and apply fresh solder to one of the solder pads.
• Using a pair of tweezers, position the new chip component in place while heating the fresh
solder.
• Once solder wicks onto the new component, remove the heat from the solder.

•

• 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:
• Use the hot-air hand piece and reflow the solder on the solder pads to smooth it.
• Apply a drop of solder paste flux to each pad.
• Using a pair of tweezers, position the new component in place.
• Position the hot-air hand piece approximately 1/8” (0.3 cm) above the component and begin
applying heat.

•

•

• Once the solder wicks to the component, remove the heat and inspect the repair. All joints
should be smooth and shiny.
Shields
Removing and replacing shields will be done with the R1319A station with the temperature
control set to approximately 415°F (215°C) [445°F (230°C) maximum].
To remove the shield:
• Place the circuit board in the R1319A holder.
• Select the proper heat focus head and attach it to the heater chimney.
• Add solder paste flux around the base of the shield.
• Position the shield under the heat-focus head.
• Lower the vacuum tip and attach it to the shield by turning on the vacuum pump.
• Lower the focus head until it is approximately 1/8” (0.3 cm) above the shield.
• Turn on the heater and wait until the shield lifts off the circuit board.
• Once the shield is off, turn off the heat, grab the part with a pair of tweezers, and turn off the
vacuum pump.

•

• Remove the circuit board from the R1319A circuit board holder.
To replace the shield:
• Add solder to the shield if necessary, using a micro-tipped soldering iron.

4-4

Maintenance

• Next, 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.
• Place the circuit board back in the R1070’s circuit board holder.
• Place the shield on the circuit board using a pair of tweezers.
• Position the heat-focus head over the shield and lower it to approximately 1/8” (0.3 cm)
above the shield.
• Turn on the heater and wait for the solder to reflow.
• Once complete, turn off the heat, raise the heat-focus head and wait approximately one

Maintenance

In cases where the radio fails to turn on when power is applied, the circuit board fuse should always
be checked as a probable cause of the failure. The locations of the fuse for both the UHF and VHF
boards are shown in Figure 4-1.The radio must be disassembled to replace the fuses as described
inthe Basic Service Manual (see Chapter 1 - Related Documents), then the circuit board separated
from the radio chassis as described in the paragraphs that follow.

Maintenance

Removing and Reinstalling the Circuit Board
Both the 200MHz and 700 MHz circuit boards are removed from the radio chassis in the following
manner:
1. Refer to the Basic Service Manual (see Chapter 1 - Related Documents) for radio disassembly,
then use a Torx driver and a T-6 bit to remove the four Torx screws shown in Figure 4-2.
2. Lift the circuit board out of the radio chassis, then remove and discard the thermal pad located
between the circuit board and chassis.
3. After repairs, replace the thermal pad (Motorola P/N 7580556Z01) then reinstall the circuit board
into the radio chassis.
4. Reinstall and tighten the four Torx screws to secure the circuit board to the chassis.
5. Refer to the Basic Service Manual to reassemble the radio.

Power Up Self-Test Error Codes
Turning on the radio starts a self-test routine that checks the RAM, ROM checksum, EEPROM
hardware and EEPROM checksum. If these checks are successful, the radio generates two highpitched self-test pass tones. If the self-test is not successful, one low-pitched tone is heard. Radios
with displays are able to display the error codes. The displayed error codes and related corrections
are as follows:
If the error code
displayed is ...

Introduction
This chapter provides schematic diagrams, overlays, and parts lists for the radio circuit boards and
interface connections.

5.1.1

Notes For All Schematics and Circuit Boards
* Component is frequency sensitive. Refer to the Electrical Parts List for value and usage.
1. Unless otherwise stated, resistances are in Ohms (k = 1000), and capacitances are in picofarads
(pF) or microfarads (µF).
2. DC voltages are measured from point indicated to chassis ground using a Motorola DC multimeter or equivalent. Transmitter measurements should be made with a 1.2 µH choke in series with
the voltage probe to prevent circuit loading.
3. Reference Designators are assigned in the following manner:
