CIRCUIT DESCRIPTION
1) Receiver System
The receiver system is the double superheterodyne.
The first IF is 23.05MHz and the second IF is 450kHz.

1. Front End
The signal from the antenna is passed through a low-pass filter and input to RF
coil L21.
The signal from L21 is amplified by Q10, Q12 and led to the band pass filter, and
led to the first mixer base of Q7.

2. First Mixer
*
The amplified signal (10) by Qio, QtZ is mixed with the first local oscillator signal
(fO-23.05MHz) from the PLL circuit by the first stage mixer Q7 and so is converted
into the first IF signal.
The unwanted frequency band of the first IF signal is eliminated by the monolithic
crystal filter FL1, and led to IF amplifier Q9.

3. IF Circuit
The first IF signal is amplified by Q9, and input to pin 16 of IC2, where it is mixed
*
with the second local oscillator signal (22.6or23.5MHz) and so is converted into
the second IF signal (450kH2).
The second IF signal is output from pin3 of IC2, and unwanted frequency band of
second IF signal is eliminated by a ceramic filter FL2.
The resulting signal is tnen amplified by the second IF limiting amplifier, and
detected by quadrature circuit The audio signal is output from pin9 of IC2,

4. Audio Circuit
The detected signal from IC2 is passed through the low-pass filter and led to the
amplifier Q307, Q306.
Q308 is switched ON/OFF by AFC signal from CPU.
The audio signal is input to the main volume VR301 and amplified by the power
amplifier IC302 to drive the speaker.
The power supply voltage of IC302 is limited by AF regulator consisting of Q304.
The power supply voltage of IC302 is switched ON/OFF by AFP signal from CPU.

5. Squelch Circuit
The noise in the audio signal from IC2 is passed through the squelch control
variable resistor RT2 and input pin8 of IC2.
IC2 includes filler amplifier, high-pass filter and rectifier.
When squelch circuit is close, pin13 of IC2 goes to "High".
When squelch circuit is open or a signal is received, pin13 of IC2 goes to "Low“,
then the signal of pin13 is led to CPU.

* for S41 only.

2) PLL, VCO Circuit
Output frequency of PLL circuit is set by the serial data from microprocessor.
PLL circuit consists of VCO Q101, buffer amplifier Q102.
The pulse wave output of charge pump is converted to DC voltage by PLL loop
filter circuit, and supplied to D102, D103 of varicap diode in VCO unit.
The frequency modulation is executed when audio signal voltage is supplied to the
varicap D104.
When PLL is unlocked, pin7 of IC1 goes to "High".

3) Transmitter System
1. Microphone Amplifier
The voice from the internal or external microphone is !ed to the pre-emphasis
circuit, and then input to the microphone amplifier IC301, which consists of two
operational amplifiers.
The amplified is signal is input to the low-pass filter IC301.
The output from the microphone amplifier is passed through variable resistors
RT301 for modulation adjustment to varicap diode of the VCO.

2. Power Amplifier
The signal from VCO is passed through Tx/Rx switch circuit D3.
The signal is amplified by Q4 and 05, and input to power amplifier 02, 03, 06,
and then passed through the low-pass filter, the antenna switch circuit and the
output low-pass filter.
The unwanted harmonics frequency signal is eliminated by the low-pass filter and
input to fhe antenna.
