UHF TRANSCEIVERS

This service manual describes the latest technical
information for the IC-F4101D, IC-F4102D, IC-F4103D and
IC-F4106D UHF 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 any liquids.
DO NOT reverse the polarities of the power supply when
connecting 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
4-1 RECEIVER CIRCUITS
RF CIRCUITS
The RX signal from the antenna is passed through the LPF
and antenna SW (D3, D22), 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 circuits.
The BPFs are tuned to the RX frequency by applying ad-
equate tuning voltages: “T1” and “T2” to the variable capaci-
tors.
1ST IF CIRCUITS
The RX signal from the RF circuits 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
circuits.
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).
• WHILE OPERATING IN THE ANALOG MODE
The 2nd IF signal is filtered by the 2nd IF filter (FI3: wide/
middle mode) or filters (FI3 and FI4: narrow) to eliminate un-
wanted signals. It is amplified by the 2nd IF AMP, and then
demodulated by the detector circuit, which employs the dis-
criminator (X1) as the phase shifter.
The demodulated AF signal is amplified by the AF AMP
(IC21), and then applied to the linear codec (IC902) through
the filter SW (Q901). The filter SW toggles the frequency re-
sponse of the AF filter (R904, R908, C924), according to the
type of reception; Wide, Mid or Narrow.
The AF signal is converted into a digital audio signal by the
linear codec (IC902), processed by the DSP (IC903), and
then 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 directly ap-
plied to the DSP (IC903).
The 2nd IF signal is demodulated by the DSP (IC903), and
then applied to the linear codec (IC902) to be decoded into
an analog audio signal.
The AF signal is applied to the RX AF circuits.

RX AF CIRCUITS
The demodulated AF signal from the linear codec (IC902) is
passed through the LPF (IC60C), and then adjusted in level
by the D/A converter (IC57). The level-adjusted AF signal is
then amplified by AF AMPs (IC58 and IC55).
The amplified AF signal is applied to the internal or external
speaker.
SQUELCH CIRCUITS (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 emitted.
A portion of demodulated AF signal from the IF IC (IC3) is
passed through the D/A converter (IC57) for level (=thresh-
old) adjustment. The level-adjusted AF signals are passed
through the noise filter (IC3, pins 7, 8 and R139–R142,
C241–C243) to filter the noise components (approx. 30 kHz
signals) only. The noise components are rectified, resulting
in 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 controlls the AF
power AMP (IC55) to “Low,” to inactivate it.

4-2 TRANSMITTER CIRCUITS
TX AF CIRCUITS
The audio signal from the internal or external microphone
(MIC signal) is passed through the MIC gain SW (IC62), and
then applied to the MIC AMP (IC64).
• WHILE OPERATING IN THE ANALOG MODE
The amplified MIC signal is passed through the HPF (IC63A),
which attenuates frequencies 300 Hz and below, and then
applied to the limiter AMP (IC60A), through the mute SW
(Q66).
The amplitude-limited MIC signal is applied to the lin-
ear codec (IC902), through the MIC line SW (IC66).
The MIC signal is converted into a digital audio signal by the
linear codec (IC902), processed by the DSP (IC903), 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 (IC63B) which
keeps the signal level fixed.
The level-adjusted MIC signal is
applied to the linear codec
(IC902) through the MIC line SW (IC66).
The MIC signal is converted into a digital audio signal by the
linear codec (IC902), processed by the DSP (IC903), and
then converted into the digital baseband signal (modulation
signal).
The signal from the linear codec (IC902) is passed through
the LPF (IC60B), and then applied to the D/A converter
(IC57)
which adjusts its level (=deviation) . The level-adjusted
modulation signal is applied to the modulation circuit.

MODULATION CIRCUIT
The modulation signal from the TX AF circuits is applied to
D15 of the TX VCO (Q14, D14–D16) 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 circuits through the
LO SW (D5).
TX AMPLIFIERS
The buffer amplified signal from the LO SW (D5) is sequen-
tially amplified by the pre-AMP (Q4), pre-drive AMP (Q3),
drive AMP (Q2), and power AMP (Q1), to obtain TX power.
The amplified TX signal is passed through the antenna SW
(D3, D22) and the LPF, which eliminates harmonics, and
then fed to the antenna.
APC CIRCUITS
D1 and D2 rectify a portion of the TX signal to direct voltage,
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.

4-3 FREQUENCY SYNTHESIZER CIRCUITS
The RX VCO is composed of Q13, and D11, D12. 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 LPF (L18, C208, C209).
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-AMP (Q4), 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, C168).
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.
