SECTION 4 CIRCUIT DESCRIPTION
4-1 RECEIVER CIRCUITS
4-1-1 ANTENNA SWITCHING CIRCUIT (MAIN unit)
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.
Received signals enter the antenna connector and pass
through the low-pass filter (L1–L3, C1, C3, C8–C11, C13).
The filtered signals are then applied to the RF circuit passed
through the λ⁄4type antenna switching circuit (D13, D14,
L18).
4-1-2 RF CIRCUIT (MAIN unit)
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 pass through
the attenuator circuit (D13, D14) and the two-stage tunable
bandpass filters (D16, D17). The filtered signals are ampli-
fied at the RF amplifier (Q12) and then enter the another
two-stage bandpass filters (D18–D21) to suppress unwant-
ed signals. The filtered signals are applied to the 1st mixer
circuit (Q13).
The tunable bandpass filters (D16–D21) employ varactor
diodes to tune the center frequency of the RF passband for
wide bandwidth receiving and good image response rejec-
tion. These diodes are controlled by the CPU (FRONT unit;
IC1) via the level controller (IC5).
The attenuator circuit (D13, D14) functions only when the
attenuator function is assigned to a programable key and
turnes on to protect the RF amplifier from distortion caused
by receiving excessively strong signals.
When the attenuator function is turned on, CPU (FRONT
unit; IC1, pin 32) switches the voltage level of the “RF ATT”
line from high to low and then controls the attenuator switch
(Q35). In this case, the current of D13, D14 is increased and
D13, D14 act as an attenuator.
4-1-3 1ST MIXER AND 1ST IF CIRCUITS
(MAIN unit)
The 1st mixer circuit converts the received signals to a fixed
frequency of the 1st IF signal with the PLL output frequency.
By changing the PLL frequency, only the desired frequency
will pass through a pair of crystal filters at the next stage of
the 1st mixer.
The RF signals from the bandpass filter are applied to the
1st mixer circuit (Q13). The applied signals are mixed with
the 1st LO signal coming from the VCO circuit (Q7, Q8) to
produce a 31.05 MHz 1st IF signal. The 1st IF signal pass-
es through a pair of crystal filters (FI1a/b) to suppress out-
of-band signals. The filtered signal is amplified at the 1st IF
amplifier (Q14) and applied to the 2nd IF circuit.
4-1-4 2ND IF AND DEMODULATOR CIRCUITS
(MAIN unit)
The 2nd mixer circuit converts the 1st IF signal to a 2nd IF
signal. A double-conversion superheterodyne system
improves the image rejection ratio and obtains stable receiv-
er gain.
The 1st IF signal from the IF amplifier (Q14) is applied to the
2nd mixer section of the FM IF IC (IC3, pin 16) and is then
mixed with the 2nd LO signal for conversion to a 450 kHz
2nd IF signal.
IC3 contains the 2nd mixer, limiter amplifier, quadrature
detector, active filter and noise amplifier circuits, etc. A dou-
bled frequency from the PLL reference oscillator is used for
the 2nd LO signal (30.6 MHz).
The 2nd IF signal from the 2nd mixer (IC3, pin 3) passes
through ceramic filters (FI3 and FI4) during narrow channel
spacing selection or passes through FI4 (bypassing FI3)
only during wide channel spacing selection. It is then ampli-
fied at the limiter amplifier section (IC3, pin 5) and applied to
the quadrature detector section (IC3, pins 10, 11 and X3) to
demodulate the 2nd IF signal into AF signals.
The AF signals are output from pin 9 (IC3) and are then
applied to the AF amplifier circuit.

4-1-5 AF AMPLIFIER CIRCUIT (MAIN unit)
The AF amplifier circuit amplifies the demodulated AF sig-
nals to drive a speaker.
AF signals from the FM IF IC (IC3, pin 9) are amplified at the
AF amplifier (IC7a) and then pass through the AF switching
IC (IC4, pins 1, 2) and high-pass filter (IC8) whose charac-
teristics are controlled by the “AFHPF” line. When “AFHPF”
is at a high level, the cut off frequency is shifted higher to
remove CTCSS or DTCS signals.
The filtered signals from IC8 (pin 7) are amplified at the lim-
iter (IC7b) and buffer (IC7c) amplifiers, and passed through
the de-emphasis circuit (R145, C182) with frequency char-
acteristics of –6 dB/octave, and are then applied to the level
controller (IC5). The audio level controlled signals are
passed through the low-pass filter (IC6b) and AF switching
IC (IC4, pins 8, 9), and are then power amplified at the AF
amplifier (IC10) to drive a speaker via the buffer amplifier
(IC6d).
4-1-6 RECEIVER MUTE CIRCUITS
(MAIN and FRONT units)
• NOISE SQUELCH
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.
Aportion of the AF signals from the FM IF IC (IC3, pin 9) are
applied to the level controller (IC5, pin 24). The level con-
trolled noise components are output from pin 23 and are
applied to the active filter in IC3 (pin 8). Noise components
of about 10 kHz are amplified and output from pin 7 and are
then applied to the noise detector section (pins 10, 11). The
detected noise signals are rectified and output from pin 13
without smoothing.
The noise signal (NOIS) from IC3 (pin 13) is applied to the
CPU (FRONT unit; IC1, pin 19). The CPU analyzes the
noise condition and outputs the RMUT signal via the I/O
expander IC (IC11) to toggle the AF mute switches (IC4a/c).
• CTCSS AND DTCS
The tone squelch circuit detects AF signals and opens the
squelch only when receiving a signal containing a matching
subaudible tone (CTCSS or DTCS). When tone squelch is in
use, and a signal with a mismatched or no subaudible tone
is received, the tone squelch circuit mutes the AF signals
even when noise squelch is open.
A portion of the AF signals from the AF amplifier (IC7a)
passes through the low-pass filter (FRONT unit; Q5) to
remove AF (voice) signals and is applied to the CTCSS or
DTCS decoder inside the CPU (FRONT unit; IC1, pin 97) via
the “CTCIN” line to control the AF mute switch via the I/O
expander IC (IC11).
4-2 TRANSMITTER CIRCUITS
4-2-1 MICROPHONE AMPLIFIER CIRCUIT
(MAIN unit)
The microphone amplifier circuit amplifies the audio signals
from the microphone, within +6 dB/octave pre-emphasis
characteristics, to a level needed for the modulation circuit.
The AF signals from the microphone are amplified at the AF
amplifier (IC7d) and are then passed through the pre-
emphasis circuit (R172, C295) which has +6 dB/octave pre-
emphasis characteristics.
The pre-emphasized signals are applied to the AF switching
IC (IC4, pins 4, 3), and are then passed through the high-
pass filter (IC8a/b). The filtered signals are amplified at the
limiter (IC7b) and buffer (IC7c) amplifiers.
The signals are applied to the level controller (IC5, pins 16,
15). The deviation level controlled signals are passed
through the splatter filter (IC6b) and AF switching IC (IC4,
pins 11, 10), and are then applied to modulation circuit as
the “MOD” signal.
The narrow/wide switch (Q21) is connected to the input of
the splatter filter (IC6b) and switched by the “NWC” signal
coming from the I/O expander IC (IC11). When “NWC” is at
a high level, the narrow/wide switch (Q21) shifts the filter
cut-off frequency for narrow deviation selection.
4-2-2 MODULATION CIRCUIT (MAIN unit)
The modulation circuit modulates the VCO oscillating signal
(RF signal) using the microphone AF signals.
The “MOD” signals from the AF switching IC (IC4, pin 10)
change the reactance of D9 to modulate the oscillated sig-
nal at the VCO circuit (Q7, Q8). The modulated signal is
amplified at the buffer amplifiers (Q6, Q4) and is then
applied to the drive amplifier circuit.

4-2-3 DRIVE AMPLIFIER CIRCUIT (MAIN unit)
The drive amplifier circuit amplifies the VCO oscillating sig-
nal to the level needed at the power amplifier.
The RF signal from the buffer amplifier (Q4) passes through
the T/R switch (D5) and is amplified at the buffer (Q3, Q2)
and drive (Q1) amplifiers. The amplified signal is applied to
the power amplifier circuit.
4-2-4 POWER AMPLIFIER CIRCUIT (MAIN unit)
The power amplifier circuit amplifies the driver signal to an
output power level.
The RF signal from the drive amplifier (Q1) is applied to the
power module (IC1) to obtain 45 W (for IC-F320; 25 W for
IC-F310) of RF power.
The amplified signal is passed through the antenna switch-
ing circuit (D3, D4), low-pass filter and APC detector, and is
then applied to the antenna connector.
Collector voltages for the driver (Q1) and control voltage for
the power amplifier (IC1, pin 2) come from APC controller
(Q17, Q18) to stabilize the output power. The transmit mute
switch (Q23) controls theAPC controller when transmit mute
is necessary.
4-2-5 APC CIRCUIT (MAIN unit)
The APC circuit protects the power amplifier from a mis-
matched output load and stabilize the output power.
The APC detector circuit (D1, D2) detects forward signals
and reflection signals at D2 and D1 respectively. The com-
bined voltage is at minimum level when the antenna imped-
ance is matched at 50 Ωand is increased when it is mis-
matched.
The detected voltage is applied to the inverse amplifier
(IC6c, pin 9), and the power setting voltage (T4) is applied
to the other input (pin 10) for the reference. When antenna
impedance is mismatched, the detected voltage exceeds
the power setting voltage. The output voltage of the inverse
amplifier (IC6c, pin 8) controls the input current of the power
module (IC1) and drive amplifier (Q1) to reduce the output
power via the APC controller (Q17, Q18).
4-3 PLL CIRCUITS
4-3-1 PLL CIRCUIT
A PLL circuit provides stable oscillation of the transmit fre-
quency and receive 1st LO frequency. The PLL circuit con-
sists of the PLL IC (IC2), loop filter and reference oscillator
circuit and employs a pulse swallow counter.
An oscillated signal from the VCO (Q7, Q8) passes thorough
the buffer amplifiers (Q6, Q5) is applied to the PLL IC (IC2,
pin 2) and is prescaled in the PLL IC based on the divided
ratio (N-data). The reference signal is generated at the ref-
erence oscillator (X1) and is also applied to the PLL IC. The
PLL IC detects the out-of-step phase using the reference
frequency and outputs it from pin 8. The output signal is
passed thorough the loop filter (R43–R45, C60, C61) and is
then applied to the VCO circuit as the lock voltage.
4-3-2 VCO CIRCUIT (MAIN unit)
The VCO oscillated signal is amplified at the buffer ampli-
fiers (Q6, Q4) and is then applied to the T/R switching circuit
(D5, D6). The Rx signal is applied to the 1st mixer circuit
(Q13) via the bandpass filter (L23, L24, C116–C118) and the
Tx signal to the driver (Q1) via the buffer amplifers (Q2, Q3).
A portion of the signal from Q6 is amplified at the buffer
amplifier (Q5) and is then fed back to the PLL IC (IC2 pin 2).

5-1 PREPARATION
‘‘REQUIRED TEST EQUIPMENT
‘‘ADJUSTMENT FREQUENCY DATA
Before starting the adjustment, back up the original frequen-
cy data and program adjustment frequency data at right
using the optional programming software (EX-2057 Rev. 1.0
or later for IC-F310/F320, CS-F300S for IC-F310S/F320S),
cloning cable (OPC-478), and adaptor cable (OPC-592) for
your convenience.
‘‘TRIMMER ADJUSTMENT
When you adjust the contents on page 5-4, TRIMMER ADJUSTMENT, the optional EX-2057, OPC-478 and JIG CABLE are
required.
• STARTING TRIMMER ADJUSTMENT
Turn the transceiver power ON, connect a computer to the [MIC] jack using the optional OPC-478 CLONING CABLE and JIG
CABLE, then start up the "ADJUST" program in EX-2057 or CS-F300S.
•STARTING THE PROGRAM
qBoot up DOS.
wInsert the EX-2057 or CS-F300S backup disk into driveA.
eType the following to start up the program:
ADJ>ADJUST [/A : /B]*1[/1 : /2]*2[Enter]
• The adjustment screen appears after reading set data
from the transceiver.
rAfter the adjustment screen appears, set or modify the
data as desired.
*1PLL reference crystal type.
/A: Normal crystal type. (You must select [/A] for IC-
F310/F310S/F320/F320S’s adjustment.)
/B: This does not activate for IC-F310/F320’s adjust-
ment.
*2RS-232C port number.
NOTE: When the EEPROM (FRONT unit; IC3) is replaced or the transceiver displays an error message and beeps, the
following operation is necessary before starting the ADJUSTMENT.
1. Download the programmed data using the EX-2057 or CS-F300S from an exact same version of the transceiver, then
save it. (See the instructions for detailed operation.)
2. Set the cursor to the [MODEL] and push the [↓] key on the computer keyboard.
3. Type "RESERVE" then push [Enter].
"Reserved" indicator flashes at the right hand, top corner on the computer screen.
4. Connect the transceiver which has been repaired, then write the data to the transceiver.
