SECTION 4 CIRCUIT DESCRIPTION
4 - 1
4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT
Received signals passed through the low-pass filter (L1, L2,
C1–C5). The filtered signals are applied to the 1/4 λtype
antenna switching circuit (D1, D2, D8, L15, C76).
The antenna swtiching circuit functions as a low-pass filter
while transmitting. However, its impedance becomes very
high while D2 and D8 are turn ON. Thus transmit signals are
blocked from entering the receiver circuits. The antenna
switching circuit employs a 1/4 λtype diode swtiching sys-
tem. The passed signals are then applied to the RF amplifi-
er circuit.
4-1-2 RF CIRCUIT
The RF circuit amplifies signals within the range of frequen-
cy coverage and filters out-of-band signals.
The signals from the antenna switching circuit are applied to
the limitter (D50), and are then passed through the band-
pass filter (D9, L16, C80). The filtered signals are amplified
at the RF amplifier (Q12), then applied to the 1st mixer cir-
cuit after out-of-band signals are suppressed at the band-
pass filter (D11, D12, L19, C91–C97).
D9, D11, D12 employ varactor diodes that track the band-
pass filters and are controlled by the T1–T3 signals from the
D/A convertor (IC10, pins 2, 3, 10). These diodes tune the
center frequency of an RF passband for wide bandwidth
receiving and good image response rejection.
4-1-3 1ST MIXER AND 1ST IF CIRCUITS
The 1st mixer circuit converts the received signal to 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 two crystal filters at the next stage of the
1st mixer.
The signals from the RF circuit are mixed at the 1st mixer
(Q13) with a 1st LO signal coming from the VCO circuit to
produce a 21.70 MHz 1st IF signal.
The 1st IF signal is applied to two crystal filters (FI1 and FI3)
to suppress out-of-band signals. The filtered 1st IF signal is
applied to the IF amplifier (Q14), then applied to the 2nd
mixer circuit (IC1, pin 16).
4-1-4 2ND IF AND DEMODULATOR CIRCUITS
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
ratio and obtain stable receiver gain.
The 1st IF signal from the IF amplifier is applied to the 2nd
mixer section of the FM IF IC (IC2, pin 16), and is mixed with
the 2nd LO signal to be converted to a 450 kHz 2nd IF sig-
nal.
The FM IF IC contains the 2nd mixer, limiter amplifier, quad-
rature detector and active filter circuits.A21.25 MHz 2nd LO
signal is produced at the PLL circuit.
The 2nd IF signal from the 2nd mixer (IC2, pin 3) passes
through a ceramic filter (FI2) to remove unwanted hetero-
dyned frequencies. It is then amplified at the limiter amplifi-
er (IC2, pin 5) and applied to the quadrature detector (IC2,
pins 10, 11) to demodulate the 2nd IF signal into AF signals.
4-1-5 AF CIRCUIT
The AF amplifier circuit amplifies the demodulated AF sig-
nals to drive a speaker.
AF signals from the FM IF IC (IC2, pin 9) are applied to the
analog swtich (IC4, pin 1) via the AF filter circuit (IC3b, pins
6, 7). The output signals from pin 2, 3 are passed through
the low-pass filter (IC3d, pins 13, 14), and are then applied
to the analog swtich (IC4, pin 9, 10) again. The signals from
the IC4, pin 11 are applied to the AF power amplifier (IC5,
pin 4) after passing through the D/A convertor (IC10, pins
12, 11).

The AF signals are applied to the AF power amplifier circuit
(IC5, pin 4) to obtain the specified audio level. The amplified
AF signals, output from pin 10, are applied to the internal
speaker (SP1) via the speaker jack (CHASSIS unit; J3)
when no plug is connected to the jack.
4-1-6 SQUELCH CIRCUIT
Asquelch circuit cuts outAF signals when no RF signals are
received. By detecting noise components in the AF signals,
the squelch switches the analog swtich.
Aportion of theAF signals from the FM IF IC (IC2, pin 9) are
applied to the active filter section (IC2, pin 8) where noise
components are amplified and detected with an internal
noise detector.
The trigger circuit converts the detected signals to a HIGH
or LOW signal and applies this (from pin 13) to the CPU
(IC8, pin 19) as the NOIS signal. When the CPU receives a
HIGH level NOIS signal, the CPU controls the RMUT line to
cut theAF signals at the analog swtich IC (IC4).At the same
time, the AFON line controls the AF regulator circuit (Q15,
Q16) to cut out the VCC power source for the AF power
amplifier (IC5).
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT
The microphone amplifier circuit amplifies audio signals with
+6 dB/octave pre-emphasis from the microphone to a level
needed for the modulation circuit.
The AF signals from the microphone are applied to the
microphone amplifier circuit (IC3c, pin 10). The amplifiedAF
signals are passed through the low-pass filter circuit (IC3d,
pins 13, 14) via the analog swtich (IC4, pins 4, 3). The fil-
tered AF signals are applied to the modulator circuit after
passing through the analog swtich (IC4, pins 8, 9).
4-2-2 MODULATION CIRCUIT
The modulation circuit modulates the VCO oscillating signal
(RF signal) using the microphone audio signals.
The audio signals (SHIFT) change the reactance of D37 to
modulate an oscillated signal at the VCO (Q50, D38). The
oscillated signal is amplified at the LO (Q6) and buffer (Q4)
amplifiers, then applied to the TX/RX switch circuit (D3, D4).
4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS
The signal from the VCO circuit passes through the TX/RX
swtiching circuit (D3) and is amplified at the pre-drive (Q3),
drive (Q2) and power (Q1) amplifiers to obtain 5.5 W of RF
power (at 7.2 V DC/typical). The amplified signal passes
through the low-pass filter (L4, C278, C287), and then
applied to the antenna swtiching circuit (D1). The signal is
applied to the antenna connector (J1) after being passed
through the low-pass filter (L1, L2, C1–C5).
The bias current of the drive (Q2) and power (Q1) amplifiers
is controlled by the APC circuit to stabilize the output power.
4-2-4 APC CIRCUIT
The APC (Automatic Power Control) circuit (IC3a, Q37) pro-
tects drive and power amplifiers from excessive currents
and selects HIGH or LOW output power.
The output voltage from the power detector circuit (D32,
D33) is applied to the differential amplifier (IC3a, pin 2), and
the “T3”signal from the D/A convertor (IC10, pin 10) is
applied to the other input for reference.
When the driving current increases, the input voltage of the
differential amplifier (IC3a, pin 2) will be increased. In such
cases, the differential amplifier output voltage (pin 1) is
decreased to reduce the drive current.
Q37 is controlled by the TXC signal from the CPU (IC8, pin
55) to select HIGH or LOW output power.

4-3 PLL CIRCUITS
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
the divided ratio (N-data) of a programmable divider.
The PLL circuit contains the VCO circuit (Q50, D38). The
oscillated signal is amplified at the LO (Q6) and buffer (Q5)
amplifiers and then applied to the PLL IC (IC1, pin 6).
The PLL IC contains a prescaler, programmable counter,
programmable divider, phase detector, charge pump, etc.
The entered signal is divided at the prescaler and program-
mable counter section by the N-data ratio from the CPU.
The divided signal is detected on phase at the phase detec-
tor using the reference frequency.
If the oscillated signal drifts, its phase changes from the ref-
erence frequency, causing a lock voltage change to com-
pensate for the drift in the oscillated frequency.
A portion of the VCO circuit is amplified at the LO (Q6) and
buffer (Q4) amplifiers and is then applied to the receive 1st
mixer or transmit pre-drive amplifier circuit via the TX/RX
swtiching diode (D3, D4).
4-4 OTHER CIRCUITS
4-4-1 TONE SQUELCH CIRCUIT
A portion of the detected audio signals from the “DET”line
are passed through the tone filter (Q53). The filtered signal
is then applied to the CPU (IC1, pin 94) via the “CTCIN”sig-
nal, and is compared with the programmed tone signal. The
CPU (IC1) outputs control signals as “CTCC”signal to the
AF mute and AF regulator circuits to open the squelch when
a matched tone signal is received.
The programmed subaudible tone signal is output from the
CPU (IC1, pin 91) directly when transmitting with a tone.
