SECTION 4 CIRCUIT DESCRIPTION
4-1-3 2ND IF AND DEMODULATOR CIRCUITS
(MAIN UNIT)

4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT
(MAIN UNIT)

The 2nd mixer circuit converts the 1st IF signal to a 2nd IF
signal. A double conversion superheterodyne system (which
converts receive signal twice) improves the image rejection
and obtain stable receiver gain.

The antenna switching circuit functions as a low-pass filter
while receiving and as resonator circuit while transmitting.
The circuit does not allow transmit signals to enter receiver
circuits.

The 1st IF signal is applied to a 2nd mixer section of the FM
IF IC (IC170, pin 16). The signal is then mixed with a 2nd LO
signal for conversion into a 450 kHz 2nd IF signal.

Received signals from the antenna connector pass through
the low-pass filter (L81, L82, C83–C86, C89) and antenna
switching circuit (D52, D90). The filtered signals are then
applied to the RF amplifier circuit (Q90).

IC170 contains the 2nd mixer, limiter amplifier, quadrature
detector and active filter circuits. A 21.25 MHz 2nd LO signal
is produced at the PLL circuit using the reference frequency.

4-1-2 RF AND 1ST MIXER CIRCUITS (MAIN UNIT)
The 1st mixer circuit converts the received signals to a fixed
frequency of the 1st IF signal with a PLL output frequency.
By changing the PLL frequency, only the desired frequency
will be passed through a pair of crystal filters at the next
stage of the 1st mixer.

The 2nd IF signal from the 2nd mixer (IC170, pin 3) passes
through ceramic filters (FI170) to remove unwanted heterodyne frequencies. It is then amplified at the limiter amplifier
section (IC170, pin 5) and applied to the quadrature detector section (IC170, pins 10 and 11) to demodulate the 2nd IF
signal into AF signals.

The signals from the antenna switching circuit are passed
through the tunable bandpass filter (D92) and amplified at
the RF amplifier (Q90). The amplified signals are passed
through another tunable bandpass filter (D130), and then
applied to the 1st mixer circuit (Q150).

4-1-4 AF CIRCUIT (MAIN UNIT)
AF signals from the FM IF IC (IC170, pin 9) are fed to the
analog switch (IC260).
The AF signals (detected signals) are passed through the
analog switch (IC260, pins 2 and 1) and are then applied to
the active low-pass filter (IC200c, pin 9).

The filtered signals are mixed at the 1st mixer (Q150) with a
1st LO signal coming from the PLL circuit to produce a 21.7
MHz 1st IF signal. The 1st IF signal is passed through two
crystal filters (FI150, FI151) and is then amplified at the IF
amplifier (Q151).

The filtered AF signals are applied to and adjusted audio
level at the D/A convertor (IC190, pin 24) to adjust amplitude. The level controlled signals are passed through the AF
mute switch (Q280) which is controlled by “AFMS” signal
from the CPU (IC360, pin 47). The passed signals are
applied to the AF power amplifier (IC280, pin 4), and then
output to the internal speaker or [EXT SP] jack after being
passed through the de-emphasis circuit (R286, C285) to
obtain the –6 dB/octave frequency characteristics.

4-1-5 SQUELCH CIRCUIT (MAIN UNIT)

4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS
(MAIN UNIT)

The noise squelch circuit cuts out AF signals when no RF
signals are received. By detecting noise components in the
AF signals, the squelch circuit switches the AF mute switch.

The signal from the VCO circuit passes through the transmit/receive switching circuit (D50, D51) and is applied to the
buffer-amplifier (Q50). The amplified signal is amplified by
the pre-driver (Q53) and the power amplifier (Q54) to obtain
5 W of RF power (at 7.2 V). The amplified signal passes
through the antenna switching circuit (D52), and low-pass filter (L81, L82, C83–C86, C89) and is then applied to the
antenna connector.

A portion of the AF signals divided by C175 from the FM IF
IC (IC170, pin 9) are applied to the D/A convertor (IC190, pin
16) to adjust amplitude. The signals from the D/A convertor
(IC190, pin 15) are applied to the active filter section (IC170,
pin 8). The active filter section amplifies and filters noise
components. The filtered signals are applied to the noise
detector section and output from IC170 (pin 14) as the
“NOISV” signal.

The bias current of the pre-driver (Q53) and the power
amplifier (Q54) is controlled by the APC circuit to stabilize
the output power.

The “NOISV” signal from IC170 (pin 14) is applied to the
CPU (IC360, pin 2). The CPU compares the set squelch
level voltage and “NOISV” signal voltage to control the
squelch output.

4-2-4 APC CIRCUIT (MAIN UNIT)
The APC circuit provides stable output power from the
power amplifier even when the input voltage or temperature
changes, and, selects HIGH or LOW output power. The APC
circuit consists of a power detector and APC control circuits.

4-2 TRANSMITTER CIRCUITS
• POWER DETECTOR CIRCUIT (MAIN UNIT)
The power detector circuit (D80, C87) detects the transmit
output power level and converts it to DC voltage as the
“TDETV” signal. The detected signal is applied to the TX
control circuit.

4-2-1 MICROPHONE AMPLIFIER CIRCUIT
(MAIN UNIT)
The microphone amplifier circuit amplifies audio signals with
+6 dB/octave pre-emphasis characteristics from the microphone to a level needed for the modulation circuit.

• APC CONTROL CIRCUIT (MAIN UNIT)
The detected signal from the power detector circuit (D91,
R280) is applied to the CPU (IC360, pin 4) to control the
input voltage of the pre-driver (Q53) and the power amplifier (Q54). When the output power changes, the CPU (IC360)
outputs APC control signal to the D/A converter (IC190). And
then “PCON” signal from the D/A converter controls the APC
controller (IC50) to provide stable output power.

The AF signals from the microphone are passed through the
pre-emphasis circuit (R253, C254) and are then applied to
the microphone amplifier (IC200b). The amplified AF signals
are applied to analog switch (IC260, pin 5).
The AF signals are amplified again at the limiter-amplifier
(IC200a) and then passed through the low-pass filter
(IC200d, pins 12 and 13). The filtered audio is applied to the
RF unit as the “MOD” signal.

4-2-2 MODULATION CIRCUIT (MAIN UNIT)
The modulation circuit modulates the VCO oscillating signal
(RF signal) using the microphone audio signals.
The audio signals “MOD” change the reactance of D20 to
modulate an oscillated signal at the VCO circuit (Q21, Q22,
D22, D23). The oscillated signal is amplified at the bufferamplifiers (Q23, Q24).

4-3 PLL CIRCUIT (MAIN UNIT)

4-4 POWER SUPPLY CIRCUITS

A PLL circuit provides stable oscillation of the transmit frequency and receive 1st LO frequency. The PLL output compares the phase of the divided VCO frequency to the reference frequency. The PLL output frequency is controlled by
the divided ratio (N-data) of a programmable divider.

VOLTAGE LINES
LINE
VCC

DESCRIPTION
The voltage from the attached battery pack.

The PLL circuit contains a VCO (Q21, Q22, D22, D23). The
oscillated signal is amplified at the buffer-amplifiers (Q23,
Q25) and then applied to the PLL IC (IC1, pin 19).

CPU5V

Common 5 V converted from the VCC line by the
CPU5V regulator circuit (IC220).
The output voltage is applied to the CPU
(IC360), REG5V regulator, etc.

The PLL IC contains the prescalers, programmable counter,
programmable divider, phase selector and etc. The entered
signal is divided at the prescaler and programmable counter
sections by the N-data ratio from the CPU. The divided signal is detected on phase at the phase detector using the reference frequency.

5V

Common 5V converted from the VCC line by the
5V regulator circuit (Q223–Q225).
The output voltage is applied to the D/A converter (IC190) and PLL IC (IC1), etc.

R5V

Receive 5V converted from the 5V line by the R5
regulator circuit (Q221).
The regulated voltage is applied to the MOD
MUTE circuit (Q20, D20, D21) and receiver circuit.

V5V

Common 5V converted from the 5V line by the
V5 regulator circuit (Q220).
The regulated voltage is applied to the VCO circuit

T5V

Transmit 5V converted from the 5V line by the T5
regulator circuit (Q222).
The regulated voltage is applied to the transmitter circuit.

If the oscillated signal drifts, the phase of its frequency
changes from the reference frequency, causing a lock voltage changes to compensate for the drift in the oscillated frequency.
A portion of the VCO signal is amplified at buffer-amplifiers
(Q23, Q24) and is then applied to the receive 1st mixer
(Q150) or transmit driver via the TX/RX switching diode
(D50, D51).
