Receiver System
■Front End
The high-frequency signal from the antenna passes
through a low-pass filter and a high-frequency switch (D12,
L25 and D13) which switches between transmission and re-
ception, and goes to the BPF (L42) to remove unwanted sig-
nals. The resulting signal is amplified by high-frequency am-
plifier (Q18) and goes to the first mixer (Q19).
■First Mixer
The signal that reaches Q19 is mixed with the first local
signal from the VCO to produce a first IF signal (38.85MHz).
(Receive frequency – First local frequency
= First IF frequency = 38.85MHz)
The first IF signal passes through MCF: XF1 (monolithic
crystal filter) to remove unwanted signals.
The first IF signal is amplified by IF amplifier (Q20) and
goes to IF IC (IC2).

TK-3130/3131 CIRCUIT DESCRIPTION
■IF Amplifier
The IF circuit is integrated in the FM IC (IC2). The IF IC
contains local input, mixer, limiter amplifier, FM DET, and
low-frequency amplifier.
The IF signal coming from the IF amplifier (Q20) goes to
the IF IC mixer and is mixed with the second local signal
(38.4MHz) to produce a second IF signal.
(38.85MHz – 38.4MHz = 450kHz)
The tripled PLL reference oscillation (12.8MHz x 3) is
used for the second local signal.
The second IF signal passes through ceramic filter (CF1)
to remove unwanted signals.
The second IF signal passing through the ceramic filter
passes through the limiter amplifier consisting six differen-
tial amplifiers and is detected.
The FM detection is quadrature detection method. The
phase of the output signal from the limiter amplifier is
shifted by 90 degrees by a quad coil (L36) and compared
with the original waveform to produce detection output.
■Squelch Circuit
A squelch circuit is provided to prevent no-signal noise or
weak signals from outputting to a speaker during transmis-
sion.
■AF Circuit
The FM IC output passes through the base band IC
(IC205), mute (Q213), and amplifier (IC207). After go to AF
power amplifier IC (IC208). This IC have BTL amplifier func-
tion and electrical Volume. At internal speaker, BTL ampli-
fied. At external speaker, IC switch off the 1 channel ampli-
fier by connectors information.

Transmitter System
■Microphone Amplifier Circuit
The audio signal from the microphone passes through
the MIC amplifier (IC207). Then, the signal goes through the
base band IC (IC205) that has the 6dB/oct pre-emphasis cir-
cuit, band-pass filter (300 to 3kHz), amplifier, and limiter.
The distortion components outside the audio band are re-
moved by the splatter filter.
■Modulation Circuit
The MIC amplifier (IC207) output passes through VR201
for modulation adjustment and goes to the modulation input
of the VCO circuit for variable reactance phase modulation.
■Transmission Output Circuit
The VCO output is amplified by a high-frequency ampli-
fier (Q7~Q10), passes through a high-frequency antenna
switch, passes through a low-pass filter and goes to the an-
tenna.
The transmission output is about 1W with 3.8V DC sup-
ply at battery terminal.
■Low-Pass Filter Circuit
A three-stage Chebyshev type low-pass filter is located
between the antenna and transmit/receive switching circuit.
It removes harmonic components contained in the transmis-
sion output.

CIRCUIT DESCRIPTION
PLL System
■VCO Circuit
The VCO is housed in a shield case.
The VCO circuit consists of a transistor (Q4), a variable
capacity diode (D4) for frequency control, a variable capacity
diode (D8) for modulation, transmit/receive frequency shift
diode (D17), control transistor (Q2), variable capacitor (TC1)
for PLL lock voltage control, and oscillator buffer amplifier
(Q5).
■PLL Circuit
Frequency data is sent to the PLL IC (IC1) from the CPU
(IC204) as serial data when the power turns on, when the
channel is changed, or when transmission begins. It sets
the variable divider in the PLL IC.
The TCXO (X1) produce a 12.8MHz reference frequency.
It is divided to produce a 12.5kHz PLL comparison fre-
quency in the PLL IC.
The VCO input is divided by the divide ratio set by the
divider in the PLL IC to generate 12.5kHz. It is compared
with the reference comparison frequency by the phase
comparator to detect a phase difference.
The charge pump circuit in the PLL IC converts it to a
control voltage that can drive the VCO directly.
The control voltage passes through a loop filter which
passes low frequency and is applied to the VCO control pin
to control the oscillator frequency. The loop filter removes
unwanted harmonics and noise contained in the output from
the phase comparator and determines PLL response and
synchronizing characteristics by the amplitude and phase
characteristics (Fig. 8).
Fig. 7 VCO circuit
In receive mode, the shift signal T/R goes low, Q2 turns
off, and the shift diode (D17) not contact. Q4 produces the
first local frequency for reception.
(Receive channel frequency – 38.85MHz)
In transmit mode, the shift signal T/R goes high, Q2 turns
on and D17 does conducts. Q4 produces about 460~470
MHz and the VCO frequency equals the transmit channel
frequency.
The 3.0V circuit voltage is produced by ripple removing
filter circuit Q3.
■Unlock Detection Circuit
If the PLL cannot be synchronized for some reason or
other when switching the channel or changing between
transmission and reception, the PLL IC outputs a low unlock
detection signal. This signal goes to the CPU to inhibit trans-
mission when the PLL is unlocked.

Control System
■Reset Circuit
When a battery voltage is dropped, IC201 is detected low
voltage, and this detected signal input to IC204 for stop the
CPU function. IC200 is detected the reset voltage.
■Battery Voltage Detection Circuit
The unit detects a low battery voltage and display the
BATT indicator on the LCD. The battery voltage is divided
and applied to the analog value input pin (BATT) of the CPU,
and converted to a digital signal.
■Power Supply Circuit
The power supply voltage is maintained to 3.0V by the
series regulator (IC213). It is used as CPU power 3M. The
3C, 3R and 3T voltages are regulated by the IC209.
The B (battery voltage) is supplied to the RF final transis-
tor Q10.
The transmission power 3T is supplied to the transmis-
sion output circuit when the CPU turns Q219 on only in
transmit mode. 3T is junction to VR2 to generate PA gate
(Q10) for power alignment.
The reception power 3R is provided to the receive and IF
circuits when the CPU turns Q220 on only in receive mode.
The transmission/reception power 3C is supplied to the
VCO and PLL circuits when the CPU turns Q218 on in trans-
mit and receive modes.
If no signal is received for 10 seconds, the CPU enters
the power save mode, and turns common power 3C and
reception power 3R on for one cycle and off for three cycles
according to the signals from the CPU to save the battery
power.
