The module also has Rx and TX powerline filters.
RX and TX power line filters
Transistor Q301 is configured as a 5v power supply ripple filter. The filter reduces the
noise on the carrier and local oscillator signals.
VCO
The VCO comprises Q302, Coil L304, and varactor D301 D304 and is configured
as a Colpits oscillator. D301 D304 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

Power amplifier and harmonic filter. When D303 is forward biased (RX) , local oscillator
Frequencies at the collector of Q304 pass to the first mixer . VC1 adjusts the tuning
Voltage of the VCO to the correct operating point.
PLL IC
The reference frequency from the TCXO, at 12.8 MHZ , is connected to pin 1 of IC1(MB15E03)
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 charge pump output produces a voltage fed into 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 14 of IC1.The pulses at pin 14 of IC1 are buffered by Q6 and then integrated by R17 and
C19. The product of the integrating circuit is fed to Base of Q201.

Buffer
When the radio is in transmit mode the diode D201 is forward biases enabling the
modulated RF signal from the VCO to pass to the buffer/pre-amplifier Q204 and
associated components.
The output signal is passed from Q204 to Q205 via a matching network consisting of
Inductor L201 and C208.

The signal is then amplified for transmission by Q207, 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 L213 to L214 and C232-C234 and then to the antenna
connector (ANT).
Antenna Switch

The output of Q101 is then coupled to the first mixer.
First Mixer
Q102, 2-pole crystal filters XF1 and coils L103 and C120 form the First Mixer
and First IF Filter.
The RF signal, from the SAW filter and amplifier Q101 is
applied to the VCO local oscillator signal to make mixer.
The difference frequency of 21.4 MHz is taken from Q102 and is filtered by the crystal
filters XF1. The tuned circuits L103 and C120 and associated components provide
matching of the crystal filters to ensure a good pass-band response and selectivity.
The IF signal is amplified by Q104 and passed to the FM Detector IC.

In this case the crystal has a frequency of 20.945MHz. 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.
The output of CF1is passed via pin 5 to a high gain IF amplifier coupled to the
adjustable quadrature detector T2.Any detected signal is produced at pin 9 of
