UHF DIGITAL TRANSCEIVER

This service manual describes the latest technical informa-
tion for the IC-F6220D UHF DIGITAL TRANSCEIVER, 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.

connected from its power source.
3. DO NOT force any of the variable components. Turn them
slowly and smoothly.
4. DO NOT short any circuits or electronic parts. An insulated
tuning tool MUST be used for all adjustments.
5. DO NOT keep power ON for a long time when the trans-
ceiver is defective.
6. DO NOT transmit power into a Standard Signal Generator
or a Sweep Generator.
7. ALWAYS connect a 30/50 dB to 40/60 dB attenuator be-
tween the transceiver and a Deviation Meter or Spectrum
Analyzer, when using such test equipment.
8. READ the instructions of the test equipment thoroughly
before connecting it to the transceiver.

5-1 RECEIVER CIRCUITS
RF CIRCUIT
The RX signal from the antenna is passed through the
LPF(L1–L3, C1, C2, C4–C8, and C404) and antenna SW
(D5, D24), and then filtered by the 2-staged tuned BPFs
(D4, D21–D22) to eliminate unwanted out-of-band signals.
The filtered RX signal is amplified by the RF AMP (Q2), and
filtered by 2-staged tuned BPF (D10, D19) to obtain a good
image response, then applied to the 1st IF circuits.
The BPFs are tuned to the RX frequency by applying ad-
equate tuning voltages: “T1” and “T2” to the variable capaci-
tors.
• RF CIRCUIT
1ST IF CIRCUIT
The RX signal from the RF circuits is applied to the 1st IF
mixer (Q19) 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 (D13, D14, D17, D18) and
the crystal filter (FI4: analog mode, FI5: digital mode) to be
filtered, amplified by the 1st IF AMP (Q14), and then applied
to the 2nd IF circuits.
• 1ST IF CIRCUIT
2ND IF AND DEMODULATOR CIRCUITS
The signal from the 1st IF circuits is applied to the IF demod-
ulator IC (IC4) 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).
• WHILE OPERATING IN THE ANALOG MODE
The 2nd IF signal is filtered by the 2nd IF filter (FI2: wide
mode) or filters (FI1 and FI2: 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 is applied to the linear codec
( inside the AF CUSTOM IC (IC1010)). The AF signal is
encoded into a digital signal, then demodulated by DSP
(IC2007). The demodulated signal is then applied to the
linear codec
( inside the AF CUSTOM IC (IC1010)) to be de-
coded into an analog audio signal.
• WHILE OPERATING IN THE DIGITAL MODE
The 2nd IF signal is filtered by the 2nd IF filters (FI1 and FI2)
to eliminate unwanted signals, and applied to the IF AMP
(IC5) through the buffer (Q5). The amplified 2nd IF signal is
passed through the ceramic filter (FI3), and then applied to
the A/D converter (IC2002) to be encoded into a digital sig-
nal. The digital signal is demodulated by the DSP (IC2007),
and then applied to the linear codec
( inside the AF CUSTOM
IC (IC1010)) to be decoded into an analog audio signal.
The AF signal is applied to the RX AF circuits.

RX AF CIRCUITS
The detected audio signals adjusted by the linear codec’s
electoronic volume (inside the AF CUSTOM IC (IC1010)).
The level-adjusted AF signal is then amplified by the pre-
AMP (IC1004) and AF power AMP (IC1009).
The power amplified AF signal is passed through the exter-
nal speaker jack (J1002), and then applied to the internal
speaker.
• RX AF 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 (IC4)
is passed through the AF CUSTOM IC (IC1010) for level
(=threshold) adjustment. The level-adjusted AF signals are
passed through the noise filter (IC4, pins 7, 8 and Q9, R42,
R44–R45, C68–C70) to filter only the noise components (ap-
proximately 30 kHz signals). The noise components are rec-
tified, resulting in a DC voltage corresponding to the noise
level.
If the noise level is higher than the preset one, the internal
comparator set the “NOISE” signal to the CPU to “High,” then
the CPU turns the “AFON” signal, which controls the AF
mute SW, (Q1008, Q1012, D1007) to “Low,” to stop the AF
output.

TX AF CIRCUIT
The audio signal from the microphone (MIC signal) is passed
through the MIC AMP (IC7), and then applied to the AF CUS-
TOM IC (IC1010).
• WHILE OPERATING IN THE ANALOG MODE
The amplified MIC signal is passed through the HPF (inside
the AF CUSTOM IC (IC1010, pin 3)), which attenuates fre-
quencies 300 Hz and below, and then applied to the limiter
AMP
(inside the AF CUSTOM IC (IC1010 , pin 4)). The am-
plitude-limited MIC signal is applied to the AF CUSTOM IC
(inside the IC1010).
The MIC signal is converted into a digital audio signal by
the linear codec (inside the AF CUSTOM IC (IC1010)), pro-
cessed by the DSP (IC2007), and then converted into an
analog baseband signal (modulation signal).
• WHILE OPERATING IN THE DIGITAL MODE
The amplified MIC signal is applied to the ALC (inside the AF
CUSTOM IC (IC1010, pin10)) which keeps the signal level
fixed.
The level-adjusted MIC signal is
applied to the linear codec
( inside the AF CUSTOM IC (IC1010)) through the MIC line
SW (inside the AF CUSTOM IC (IC1010)).
The MIC signal is converted into a digital audio signal by
the linear codec (inside the AF CUSTOM IC (IC1010)), pro-
cessed by the DSP (IC2007), and then converted into the
digital baseband signal (modulation signal).
The signal from the linear codec (inside the AF CUSTOM IC
(IC1010)) is passed through the LPF (inside the AF CUS-
TOM IC (IC1010)), and then applied to the D/A converter
(inside the AF CUSTOM IC (IC1010))
which adjusts its level
(=deviation)
.
The level-adjusted modulation signal is applied to the modu-
lation circuit.

MODULATION CIRCUITS
The modulation signal from the TX AF circuits is applied to
D26 of the TX VCO (Q23, D16, D26, D64) to modulate it (FM
for the analog mode, 4FSK for the digital mode). The modu-
lated signal from the TX VCO is buffer-amplified by two buf-
fers (Q11, Q10), and applied to the TX AMP circuits through
the LO SW (D25).
• MODULATION CIRCUIT
TX AMPLIFIER
The buffer amplified signal from the LO SW (D25) is se-
quentially amplified by the pre-drive AMP (Q25), drive AMP
(Q8) and power AMP (IC3), to obtain TX power. The ampli-
fied TX signal is passed through the antenna SW (D5, D24)
and the LPFs, which eliminates harmonics, and then applied
to the antenna.
APC CIRCUIT
D11, D12 and D29 rectify a portion of the TX signal to direct
current, and the APC AMP (IC2) compares the voltage and
the TX power control reference voltage, “T1.” The resulting
voltage controls the gain of the power AMP (IC3) to keep the
TX power constant.
• TX AMPLIFIERS AND APC CIRCUIT
5-3 FREQUENCY SYNTHESIZER CIRCUIT
The RX VCO is composed of Q24, D33 and D62. The VCO
output signal is buffer-amplified by two buffers (Q11 and
Q10), and then applied to the 1st IF mixer, through the LO
SW (D15) and the attenuator.
The TX VCO is composed of Q23, D16, D26 and D64. The
VCO output signal is buffer-amplified by two buffers (Q11
and Q10), and then applied to the pre-drive AMP (Q25),
through the LO SW (D25) and the LPF.
A portion of signal generated by each VCO is fed back to the
PLL IC (IC8, pin 17), through the buffer (Q12) and the LPF
(L13, C298–C300).
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 (IC3), 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.
