VHF DIGITAL TRANSCEIVERS

This service manual describes the latest technical informa-
tion for the IC-F3210D VHF DIGITAL TRANSCEIVERS, at the
time of publication.
NEVER connect the transceiver to an AC outlet or to a DC
power supply that uses more than the specified voltage. This
will ruin the transceiver.
DO NOT expose the transceiver to rain, snow or liquids.
DO NOT reverse the polarities of the power supply when con-
necting the transceiver.
DO NOT apply an RF signal of more than 20 dBm (100 mW) to
the antenna connector. This could damage the transceiver’s
front-end.
To upgrade quality, any electrical or mechanical parts
and internal circuits are subject to change without notice
or obligation.

CIRCUIT DESCRIPTION
• RF CIRCUIT
• 1ST IF CIRCUIT
• 2ND IF AND DEMODULATOR CIRCUITS
4-1 RECEIVER CIRCUITS
RF CIRCUIT
The RX signal from the antenna is passed through the LPF
(L1–L3, C2–C7, C24, and C37) and antenna SW (D1, D22,
D23), then filtered by the 2-staged tuned BPF (D24 and
D26) to eliminate unwanted out-of-band signals. The filtered
RX signal is amplified by the RF AMP (Q22), and filtered by
another 2-staged tuned BPF (D28) to obtain a good image
response, then applied to the 1st IF circuit.
The BPFs are tuned to the RX frequency by applying ad-
equate tuning voltages: “T1” and “T2” to the variable capaci-
tors.
1ST IF CIRCUIT
The RX signal from the RF circuit is applied to the 1st IF
mixer (Q23) and mixed with the 1st LO signal from the RX
VCO, resulting in the 46.35 MHz 1st IF signal. The 1st IF sig-
nal is passed through the IF SWs (D31–D34) and the crystal
filter (FI1: analog mode, FI2: digital mode) to be filtered, am-
plified by the 1st IF AMP (Q24), then applied to the 2nd IF
circuit.
• WHILE OPERATING IN THE ANALOG MODE
The 2nd IF signal is filtered by the 2nd IF filter (FI3: wide
mode) or filters (FI3 and FI4: narrow) to eliminate unwanted
signals. It is amplified by the 2nd IF AMP, and then demodu-
lated by the detector circuit, which employs the discriminator
(X1) as the phase shifter.
The demodulated AF signal, output from pin 9, is applied to
the linear codec inside IC2 (a custom AF IC). The AF signal
is encoded into a digital signal, then demodulated by DSP
(IC903). The demodulated signal is then applied back to the
linear codec to be decoded into an analog audio signal.
• WHILE OPERATING IN THE DIGITAL MODE
The 2nd IF signal is filtered by the 2nd IF filters (FI3 and FI4)
to eliminate unwanted signals, and applied to the IF AMP
(IC5) through the buffer (Q28). The amplified 2nd IF signal is
passed through the ceramic filter (FI5), and then applied to
the A/D converter (IC901) to be encoded into a digital signal.
The digital signal is demodulated by the DSP (IC903), and
then applied to the linear codec
( inside IC2) to be decoded
into an analog audio signal.
The AF signal is applied to the RX AF circuit.

2ND IF AND DEMODULATOR CIRCUITS
The signal from the 1st IF circuits is applied to the IF demod-
ulator IC (IC3) which contains the 2nd IF mixer, 2nd IF AMP,
FM detector, squelch circuit and AF AMP in its package.
The 1st IF signal is applied to the 2nd IF mixer and mixed
with the 2nd LO signal resulting in the 450 kHz 2nd IF signal.
The 2nd LO signal is generated by tripling the 15.3 MHz
reference frequency signal generated by the reference fre-
quency oscillator (TCXO; X2).

• SQUELCH CIRCUIT
• TX AF CIRCUITS
4-2 TRANSMITTER CIRCUITS
TX AF CIRCUITS
The audio signal from the internal or external microphone
(MIC signal) is applied to IC2 (pin 13). The MIC signal is
amplified by the MIC AMP (inside IC2) and then output from
pin 11.
• WHILE OPERATING IN THE ANALOG MODE
The MIC signal is passed through the HPF (IC2, pin 1), which
attenuates frequencies 300 Hz and below, and then applied
to the limiter AMP (pin 4 of IC2).
The amplitude-limited MIC
signal is applied to IC2.
The MIC signal is converted into a digital audio signal by the
linear codec (inside IC2), processed by the DSP (IC903),
and then converted into an analog baseband signal (modu-
lation signal).
• WHILE OPERATING IN THE DIGITAL MODE
The MIC signal is applied to the ALC (IC2, pin10) which
keeps the signal level fixed.
The level-adjusted MIC signal is
applied to the linear codec
( inside IC2) through the MIC line SW (inside IC2).
The MIC signal is converted into a digital audio signal by the
linear codec (inside IC2), processed by the DSP (IC903),
and then converted into the digital baseband signal (modula-
tion signal).
The signal from the linear codec (inside IC2) is passed
through the LPF (inside IC2), and then applied to the D/A
converter (inside IC2)
which adjusts its level (=deviation) .
The level-adjusted modulation signal is applied to the modu-
lation circuit.

SQUELCH CIRCUIT (Analog mode only)
The squelch circuit cuts off the AF output signals when no
RF signals are received. Detecting noise components in the
demodulated AF signals, the squelch circuit stops audio sig-
nals being heard.
A portion of the demodulated AF signal from the IF IC (IC3)
is passed through IC2 for level (=threshold) adjustment. The
level-adjusted AF signals are passed through the noise filter
(IC3, pins 7, 8 and R139–R142, C241–C243) to filter only
the noise components (approximately 30 kHz signals). The
noise components are rectified, resulting in a DC voltage
corresponding to the noise level.
If the noise level is higher than the preset one, the internal
comparator sets the “NOISE” signal to the CPU to “High,”
then the CPU turns the “AFON” signal which controls the AF
power AMP (IC55) to “Low,” to deactivate it.
RX AF CIRCUITS
The detected audio signals adjusted by the linear codec’s
electronic volume (inside IC2). The level-adjusted AF signal
is then amplified by the pre-AMP (IC58) and AF power AMP
(IC55).
The amplified AF signal is applied to the internal or external
speaker.

4-4 VOLTAGE DIAGRAMS
Voltage from the power supply is routed throughout the transceiver, through regulators and switches.
• TX AMPLIFIERS AND APC CIRCUITS
• FREQUENCY SYNTHESIZER CIRCUIT
MODULATION CIRCUIT
The modulation signal from the TX AF circuit is applied to
D15 of the TX VCO (Q14, D14–D17) to modulate it (FM for
the analog mode, 4FSK for the digital mode). The modulated
signal from the TX VCO is buffer-amplified by two buffers
(Q8, Q10), and applied to the TX AMP circuit through the LO
SW (D5, D6).
4-3 FREQUENCY SYNTHESIZER CIRCUIT
The RX VCO is composed of Q13, and D11–D13. The VCO
output signal is buffer-amplified by two buffers (Q8 and Q10)
and applied to the 1st IF mixer, through the LO SW (D6) and
the attenuator.
The TX VCO is composed of Q14 and D14–D17. The VCO
output signal is buffer-amplified by two buffers (Q8 and Q10)
and applied to the pre-driver (Q3), through the LO SW (D5)
and the LPF.
A portion of signal generated by each VCO is fed back to
the PLL IC (IC4, pin 17) through the buffer (Q9) and the LPF
(L46, C167–C169).
The applied VCO output signal is divided and phase-com-
pared with a 15.3 MHz reference frequency signal from the
TCXO (X2), which is also divided. The resulting signal is
output from the PLL IC (IC4), and DC-converted by the loop
filter, and then applied to the VCO as the lock voltage.
When the oscillation frequency drifts, its phase changes
from that of the reference frequency, causing a lock voltage
change to compensate for the drift in the VCO oscillating fre-
quency.

TX AMPLIFIERS
The buffer amplified signal from the TX/RX SW (D5, D6) is
sequentially amplified by the pre-drive AMP (Q3), drive AMP
(Q2), and power AMP (Q1), to obtain TX power. The ampli-
fied TX signal is passed through the antenna SW (D1, D22,
and D23) and the LPF, which eliminates harmonics, and
then fed to the antenna.
APC CIRCUIT
D7 and D8 rectify a portion of the TX signal to direct current,
and the APC AMP (IC1) compares the voltage and the TX
power control reference voltage, “T1.” The resulting voltage
controls the gain of the power and drive AMPs to keep the
TX power constant.
