PAGE 4
PLL Synthesizer
The PLL synthesizer circuit is common to both the transmitter and receiver.
The synthesizer comprises:
TCXO
DC-DC
Converter
Loop Filter
Data
Charge Pump
IC1
PLL
TX OR RX
VCO
RF Out
Voltage controlled oscillator module (VCO)
The module contains two VCOs. One for producing carrier frequencies during transmit (TX
VCO) and one for producing the local oscillator frequency during receive (RX VCO). The
module also has RX and TX power line filters. Output is for PLL IC(IC1) Fin.
PAGE 5
RX and TX power line filters
Transistor Q308 is configured as a 5v power supply ripple filter. The filter reduces the noise
on the carrier and local oscillator signals.
RX VCO
The RX VCO comprises JFET Q301, coil L301 , and varactor D301 and is configured as a
Colpitts Oscillator . D301 produces a change in frequency with a change in DC voltage and
is controlled by The tuning voltage signal present at the cathode. The local oscillator signal
at the source of Q301 is Applied to the cascode buffer/amplifier formed by Q16 and Q17.The
Local signal is applied to the Mixer when diode D2 is reverse biased and D3 is forward
biased.
TX VCO
The TX VCO comprises JFET Q301,coil L303 , and varactor D302 and D303 and is
configured as A Colpitts oscillator . D302 produces a change in frequency with a change in
DC voltage and is controlled by the tuning voltage signal present at the cathode. The AF
signal at J501 pin 1 is applied to the cathode of D303 to produce FM modulation. When
diode D2 is forward biased and D3 is reversed biased the modulated RF signal at the
collector of Q16 is passed to the power Amplifier and harmonic filter via the cascade
buffer/amplifier (Q21 and Q22).
PLL IC
The reference frequency from the TCXO, at 12.8 MHZ, is connected to pin 1 of IC1 (MB1504)
The appropriate VCO is connected to pin 11.
REFDIV divides the 12.8 MHz to produce a reference frequency (Fr) of 5 or 6. 25 kHz
dependent upon channel spacing selected. VARDIV divides the prescaled VCO frequency to
produce a variable frequency (Fv). Fv and Fr are fed to the phase detector.
Phase detector
When Fv=Fr, the phase detector output (pins 15 and 16,IC1) produces narrow negative
pulses And Fv and Fr pulse widths are identical. When Fv Fr pin 15 (V) pulses negative with
pin 16 (R) remaining high. When Fv Fr pin 16 (R) pulses negative with pin 15(V) remaining
high. The signal at pin 15 and 16 is smoothed the loop filter and applied to the VCO.
Out-of-lock detector
The out-of-lock detector produces a series of logic level pulses when the
loop is out of lock at pin 7 of IC1.The pulses at pin 7 of IC1 are buffered by
Q6 and then integrated by R17 and C19. The product of the integrating
circuit is fed to IC501 pin 25.
PAGE 6
Charge Pump and Loop Filter
Transistors Q2, Q4, Q10, and associated resistors and capacitors form
the charge pump and loop Filter. The phase detector output from IC1
pins 15 and 16 are combined by the charge pump to produce a 0 to
15V tuning voltage signal.
The signal is filtered by the loop filter (R13, C16 and C17) to remove
any residual reference Frequency harmonics from the signal. After
filtering the signal is applied to the voltage controlled Oscillator
module.
DC to DC Converter
The DC-to-DC converter converts the +7.5 V to a 14-16 V supply. This
is used to provide the Tuning voltage for the VCO. A wide voltage
range is required to allow for the wideband operation of the radio.
Q506 to Q508, and associated components, form a 200kHz oscillator.
The output of the oscillator is rectified and filtered by D503, D506,
C548 and C11. The resultant 16VDC is passed to R544 and then
becomes the supply rail for the charge pump.
Dual modulus prescaler
The prescaler divides the VCO frequency by 64 or 65.
Transmitter
The transmitter comprises:
VCO Buffer
Amp
PA Module
ANTENNA
RF LPF
SWITCH
Automatic
Power Control
PAGE 7
Buffer
When the radio is in transmit mode the diode D2 is forward biases enabling the modulated RF signal
from the VCO to pass to the buffer/pre-amplifier Q21 and Q22 and associated components.
The output signal is passed from Q22 to IC5 via a matching network consisting of Inductor L7 and
C73.
PA module
The signal is then amplified for transmission by IC5, which is a power amplifier module.
Low pass filter
The amplified RF signal is passed through the stripline coupler and is fed to the harmonic low pass
filter, comprising L12 to L15 and C94-C98 and then to the antenna connector (ANT). The stripline
coupler provides a sample of the RF signal for the automatic power control.
Antenna Switch
When transmitting, the diodes D5 and D6 are forward biased, allowing the RF to pass to the antenna.
D6 is shorted to ground which makes L11 look open circuit (1/4 wave tuned stub). This prevents the
TX signal from passing to the receiver stage.
Automatic power control (APC) circuits
The automatic power control contains the stripline coupler, diode D4, variable resistor RV1, U4A
and transistors Q19 and Q23.
The RF signal present in the coupler is rectified by D4, to produce a DC voltage. This DC voltage is
passed to one input of IC4A, which is a differential amplifier. In transmit mode a DC reference level
for U4A is supplied by the potential divider R34/R35.
The reference level and the detected level from D4 are compared a difference signal is produced. The
difference signal drives Q19, which then drives Q23. Q23 controls the supply voltage to the first
amplifier stage in IC5. This control loop produces a constant power output at the antenna connector
( ANT ).
RV1 is used to adjust the voltage that is fed back from D4 which defines the output RF power level.

Antenna Switch
In receive, the diode D5 and D6 are reverse biased. L11 is now in circuit, passing the signal from the
antenna to the front end without signal loss.
Front End
The receiver signal is routed to pin 1 of the RF Front End module. It passes through the band pass
filter consisting of C800 to C808/L800 to L803.
Diode D800 serves as protection from RF overload from nearby transmitters.
The input signal is coupled to the base of Q800, which serves as an RF amplifier.
The output of Q800 is then coupled to a second band pass filter consisting of C814 to C822 / L804 to
L806.
The output of the front end module, pin6, is then coupled to the double-balanced mixer IC8.
The receiver front end module is factory pre-tuned and requires no adjustment.
Repair is effected by replacement of the entire module.
First Mixer
IC8, 2-pole crystal filters XF1 and XF2 and coils L16 and L18 form the First Mixer and First IF
Filter.
IC8 is a self-contained double balanced mixer. The RF signal, from the front end is applied to pin 4
and the VCO local oscillator signal is applied to pin 1.
The difference frequency of 45 MHz is taken from pin 5 and is filtered by the crystal filters XF1 and
XF2. The tuned circuits L16 and L18 and associated components provide matching of the crystal
filters to ensure a good pass-band response and selectivity.
The IF signal is amplified by Q24 and passed to the FM Detector IC.
Second mixer, Second IF, FM detector
The output of the IF amplifier is fed into the narrowband FM IF Integrated Circuit, IC6 (MC3371).
This is a single conversion FM receiver which contains the second mixer, second IF amplifier, and
FM detector.
PAGE 10
Crystal X1, connected to pin 1 of IC6, determines the second local oscillator frequency. In this case
the crystal has a frequency of 44.545MHz. The first IF signal is applied to the mixer and resultant
frequency of 455KHz, is the difference between the IF signal and second local oscillator.
The 455KHz IF signal is output from pin 3 and is applied to a 455KHz band-pass filter, CF1 (12.25
kHz channel spacing) or CF2 (6.25 kHz channel spacing). The selection of the filters is
accomplished by diodes D13 (input) and D14 (output) whose bias is controlled by software and
applied to the diodes from pin 21 of IC501.
The output of CF1/CF2 is passed via pin 5 to a high gain IF amplifier coupled to the adjustable
quadrature detector T2 (pin 8). Any detected signal is produced at pin 9 of IC6 and applied to the
Receiver Audio Circuit and the Mute (Squelch) Circuit.
Squelch (MUTE) Circuit
The noise detect circuit in conjunction with IC6 consists of diode D11 and RV2.
Any noise signal is amplified by IC6 internal noise amplifier rectified by D11 .D11 Signal is applied
to pin12 of IC6. The squelch trigger output (pin 14,IC6) is applied to the pin 6 of J501.
When noise is present, the voltage at pin 12 of IC6 is less than 0.7V. The squelch trigger output is
0V(logic 0) It’s make pin 6 of J501 open state.
When no noise is present, the voltage at pin 12 of IC6 exceeds 0.7v and pin 14 of IC6 IS AT
5v(logic 1). This make pin 6 of J501 short state.
Carrier Detect
A Carrier Detect (MUTE DETECT) output is available on pin 6 of J501.
AF Output Low Pass Filter
A low pass filter formed by C134, C135 and R82 removes any extraneous 455kHz energy from the
AF output of the FM receiver chip (pin 9 of IC6).
The filtered signal is passed to pin 2 of J501.
Micro controller
The PIC 16C57 microcontroller IC controls the programmable features and frequency synthesizer
data.
PAGE 11
Programming Mode
The programming mode allows the user to retrieve or program TX/RX frequencies, HI/LO power
Setting and channel spacing, when pin 9 of J501 is set to ground. Programming mode will Inhibit,
Serial communications can then be made in order to read/program the on- board EEPROM
( IC502 )which contains radio- specific data.
EEPROM
Relevant channel information, such as RX / TX frequencies, is stored in the EEPROM (IC502)
which is a 93C46. This information may be programmed and erased via the D- type socket. The
EEPROM has 1024 (8x128) capacity and is written serially.
Power supply circuit
The data radio is supplied with a nominal + 13.8V dc power supply input from external equipment
which is filtered using C532 ,L501 and C533.This supply is converted into three separate voltage
levels on the board using the switching transistor Q506 and associated components .
The +13.8Vdc supply and Q506 switching waveform are summed using D503 to supply a boosted
voltage supply, which is regulated at +16V using Zener diode D506. This supply is used as the
supply for the tuning voltage for the VCOs.
The +6V line is regulated by Zener diode D505 and filtered using L503 and C538.This +6V line is
fed to the RF circuit and is regulated to +5V using two regulators on the board.
