SECTION 4
CIRCUIT DESCRIPTION
The signals from the RF circuit are mixed at the 1st mixer
(Q16) with a 1st LO signal (393.65–423.65 MHz) coming
from the VCO circuit to produce a 46.35 MHz 1st IF signal.
4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT
The antenna switching circuit functions as a low-pass filter
while receiving. However, its impedance becomes very high
while D9 and D10 are turned ON. Thus transmit signals are
blocked from entering the receiver circuits. The antenna
The 1st IF signal is applied to a crystal filter (FI1) to sup-
press out-of-band signals. The filtered 1st IF signal is
applied to the IF amplifier (Q17), then applied to the 2nd
mixer circuit (IC3, pin 16).
λ
switching circuit employs a ⁄4 type diode switching system.
Received signals are passed through the low-pass filter (L1,
λ
L2, C3, C5, C6). The filtered signals are applied to the ⁄4
type antenna switching circuit (D9, D10).
The passed signals are then applied to the RF amplifier cir-
cuit.
4-1-4 2ND IF AND DEMODULATOR CIRCUITS
The 2nd mixer circuit converts the 1st IF signal into a 2nd IF
signal. A double conversion superheterodyne system (which
converts receive signals twice) improves the image rejection
ratio and obtains stable receiver gain.
4-1-2 RF CIRCUIT
The RF circuit amplifies signals within the range of frequen-
cy coverage and filters out-of-band signals.
The 1st IF signal from the IF amplifier is applied to the 2nd
mixer section of the FM IF IC (IC3, pin 16), and is mixed with
the 2nd LO signal to be converted into a 450 kHz 2nd IF sig-
nal.
The signals from the antenna switching circuit are amplified
at the RF amplifier (Q15) after passing through the tunable
bandpass filter (D12, L21, C104, C105). The amplified sig-
nals are applied to the 1st mixer circuit (Q19) after out-of-
band signals are suppressed at the 3 stages tunable band-
pass filter (D13, L22, C111, C113, D14, L23, C116, C117,
D15, L24, C120, C122).
The FM IF IC contains the 2nd mixer, limiter amplifier, quad-
rature detector and active filter circuits. A 2nd LO signal
(45.9 MHz) is produced at the PLL circuit by tripling it’s ref-
erence frequency.
The 2nd IF signal from the 2nd mixer (IC3, pin 3) passes
through a ceramic filter (FI2) to remove unwanted hetero-
dyned frequencies. It is then amplified at the limiter amplifi-
er (IC3, pin 5) and applied to the quadrature detector (IC3,
pins 10, 11) to demodulate the 2nd IF signal into AF signals.
Varactor diodes are employed at the bandpass filters that
track the filters and are controlled by the CPU (IC7) via the
D/A convertor (IC9) using T1–T4 signals. These diodes tune
the centre frequency of an RF passband for wide bandwidth
receiving and good image response rejection.
4-1-5 AF CIRCUIT
AF signals from the FM IF IC (IC3, pin 9) are applied to the
analog switch (IC6, pin 1) after being passed through the
high-pass filter (IC5B, pins 5, 7) via the “DET” signal. The
signals pass through the low-pass filter (IC5D, pins 13, 14),
and then applied to the analog switch (IC6, pins 9, 10) again.
The output signals from the analog swtich (IC6, pin 11) are
applied to the AF power amplifier (IC4, pin 4) after being
passed through the [VOL] control (SW-A/SW-B unit; R143)
via the “VOLIN” and “VOLOUT” signals.
4-1-3 1ST MIXER AND 1ST IF CIRCUITS
The 1st mixer circuit converts the received signal into a fixed
frequency of the 1st IF signal with a PLL output frequency.
By changing the PLL frequency, only the desired frequency
will pass through a crystal filter at the next stage of the 1st
mixer.

The applied AF signals are amplified at the AF power ampli-
fier circuit (IC4, pin 4) to obtain the specified audio level. The
amplified AF signals output from pin 10 as “AFOUT”signal
are applied to the internal speaker (SP1) as the “SP” signal
via the [SP] jack when no plug is connected to the jack.
4-2-2 MODULATION CIRCUIT
The modulation circuit modulates the VCO oscillating signal
(RF signal) using the microphone audio signal.
The audio signals change the reactance of a diode (D6) to
modulate an oscillated signal at the TX-VCO circuit (Q11).
The oscillated signal is amplified at the buffer-amplifiers (Q5,
Q7), then applied to the T/R switching circuit (D3, D4).
4-1-6 SQUELCH CIRCUIT
A squelch circuit cuts out AF signals when no RF signals are
received. By detecting noise components in the AF signals,
the squelch switches the AF mute switch.
4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS
The signal from the VCO circuit passes through the T/R
switching circuit (D3) and is amplified at the YGR (Q4, Q3),
pre-drive (Q2) and power amplifier (Q1) to obtain 4 W of RF
power (at 7.2 V DC). The amplified signal passes through
the antenna switching circuit (D1) via the power detector
(D2), and low-pass filter and is then applied to the antenna
connector.
A portion of the AF signals from the FM IF IC (IC3, pin 9) as
“DET” signal are applied to the D/A convertor IC (IC9, pin
24). The signals from the D/A convertor (IC9, pin 23) as
“SQLIN” signals are applied to the active filter section (IC3,
pin 8) where noise components are amplified and detected
with an internal noise detector.
The active filter section amplifies noise components. The fil-
tered signals are rectified at the noise detector section and
converted into “NOIS” (pulse type) signals at the noise com-
parator section. The “NOIS” signal output from IC3, pin 13,
and is applied to the CPU (IC7, pin 53).
The bias current of the pre-drive (Q2) and the power ampli-
fier (Q1) is controlled by the APC circuit.
The CPU detects the receiving signal strength from the
number of the pulses, and outputs “EXST”, “SO”, “SCK” sig-
nals. The signals are applied to the expander IC (IC15, pins
1, 2, 3), and then outputs “RMUT” signal from pin 4. This sig-
nal controls the analog switch (IC6, pin 13) to cut the AF sig-
nal line.
4-2-5 APC CIRCUIT
The APC circuit (IC2) protects the drive and the power
amplifiers from excessive current drive, and selects HIGH or
LOW output power.
The signal output from the power detector circuit (D2) is
applied to the differential amplifier (IC2, pin 3), and the “T4”
signal from the expander (IC9, pin 11), controlled by the
CPU (IC7), is applied to the other input for reference.
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT
The microphone amplifier circuit amplifies audio signals with
+6 dB/octave pre-emphasis characteristics from the micro-
phone to a level needed for the modulation circuit.
When the driving current is increased, input voltage of the
differential amplifier (pin 3) will be increased. In such cases,
the differential amplifier output voltage (pin 4) is decreased
to reduce the driving current.
The AF signals from the microphone are applied to the
microphone amplifier circuit (IC5c, pin 10) after being pass
through the high-pass filter (C186, C187). The amplified AF
signals are passed through the low-pass filter circuit (IC5d,
pins 13, 14) via the mute switch (IC6, pin 4). The filtered AF
signals are applied to the modulator circuit after being
passed through the mute switch (IC6, pins 8, 9, 10).

The pulse-type signal is converted into DC voltage (lock
voltage) at the loop filter (R40–R42, C74–C77), and then
applied to varactor diodes (D5) of the RX-VCO to stabilize
the oscillated frequency. The lock voltage is also used for
the receiver circuit for the bandpass filter center frequency.
The lock voltage from the loop filter is amplified at the buffer
amplifier (Q13) and then applied to the CPU (IC7, pin 60).
The signal is analyzed at the CPU, and then applied to the
D/A convertor (IC9). The D/A convertor outputs “T1”, “T2”,
“T3”, “T4” signals to RF bandpass filters D12–D15 to sup-
press harmonic components.
4-3 PLL CIRCUIT
4-3-1 GENERAL
A PLL circuit provides stable oscillation of the transmit fre-
quency and receive 1st LO frequency. The PLL output com-
pares the phase of the divided VCO frequency to the refer-
ence frequency. The PLL output frequency is controlled by a
crystal oscillator and the divided ratio (N-data) of a pro-
grammable divider.
The PLL circuit, using a one chip PLL IC (IC1), directly gen-
erates the transmit frequency and divided ratio based on
serial data from the CPU and compares the phases of VCO
signals with the reference oscillator frequency. The PLL IC
detects the out-of-step phase and output from pin 5.The ref-
erence frequency (15.3 MHz) is oscillated by X1.
4-3-4 VCO CIRCUIT
The VCO outputs from Q11 (TX) and Q10 (RX) are buffer
amplified at Q7 and Q6, and are then sent to the T/R switch
(D3, D4). The receive LO signal is applied to the 1st mixer
circuit (Q19) through an attenuator, and the tramsmit signal
is applied to the YGR amplifier (Q4). A portion of the VCO
output is reapplied to the PLL IC (IC1, pin 8) via the buffer
amplifier (Q6) and low-pass filter (L18, R53, C89–C91).
4-3-2 TX LOOP
The generated signal at the TX-VCO (Q11, D7) enters the
PLL IC (IC1, pin 8) and is divided at the programmable
divider section and is then applied to the phase detector
section.
The phase detector compares the input signal with a refer-
ence frequency, and then outputs the out-of-phase signal
(pulse-type signal) from pin 5.
The pulse-type signal is converted into DC voltage (lock
voltage) at the loop filter (R40–R42, C75–C77), and then
applied to varactor diodes (D6) of the TX-VCO to stabilize
the oscillated frequency.
4-3-3 RX LOOP
The generated signal at the RX-VCO (Q10, D5) enters the
PLL IC (IC1, pin 8) and is divided at the programmable
divider section and is then applied to the phase detector
section.
The phase detector compares the input signal with a refer-
ence frequency, and then outputs the out-of-phase signal
(pulse-type signal) from pin 5.
