■ Front EndThe high-frequency signal from the antenna passes
through a low-pass filter and a high-frequency switch (D101, D200, D201 and L220) which switches between transmission and reception, and goes to the BPF (L218) to remove unwanted signals. The resulting signal is amplifi ed by high-frequency amplifier (Q204) and goes to the first mixer (Q203).
■ First MixerThe signal that reaches Q203 is mixed with the fi rst local
signal from the VCO to produce a fi rst IF signal (38.85MHz). (Receive frequency – First local frequency
= First IF frequency = 38.85MHz)The fi rst IF signal passes through MCF: XF200 (monolithic
crystal fi lter) to remove unwanted signals.The fi rst IF signal is amplifi ed by IF amplifi er (Q201) and
goes to IF IC (IC200).

■ IF Amplifi erThe IF circuit is integrated in the FM IC (IC200). The IF
IC contains local input, mixer, limiter amplifi er, FM DET, and low-frequency amplifi er.
The IF signal coming from the IF amplifi er (Q201) 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 (CF200) to remove unwanted signals.
The second IF signal passing through the ceramic filter passes through the limiter amplifier consisting six differential amplifi ers and is detected.
The amplified second IF signal is demodulated by the quadrature detector with the ceramic discriminator (CD200). The demodulated signal is routed to the audio circuit.
■ Squelch CircuitA squelch circuit is provided to prevent no-signal
noise or weak signals from outputting to a speaker during transmission.
■ AF CircuitThe FM IC output passes through the base band IC
(IC300). The signal then goes through an AF volume control, and is routed to an audio power amplifi er (IC303) where it is amplfi ed and output to speaker. This IC have BTL amplifier function. At internal speaker, BTL amplified. At external speaker, IC switch off the 1 channel amplifi er by connectors information.

Narrow and wide setting can be made for each channel by switching the demodulation level. The WIDE (low level) and NARROW (high level) data is output from IC403, pin 69. When a Wide (low level) data is received, Q200 turn on. When a NARROW (high level) data is received, Q200 turn off.
Q200 turns off/on with the wide/narrow data and the IC200 detector output level is switched to maintained a constant output level during wide or narrow signals.
Transmitter System
■ Microphone Amplifi er CircuitThe audio signal from the microphone passes through
the MIC amplifier (IC302). Then, the signal goes through the base band IC (IC300) that has the 6dB/oct pre-emphasis circuit, band-pass fi lter (300 to 3kHz), amplifi er, and limiter. The distortion components outside the audio band are removed by the splatter fi lter.
■ Modulation CircuitThe MIC amplifi er (IC302) output passes through VR300
for modulation adjustment and goes to the modulation input of the VCO circuit for variable reactance phase modulation.
■ Transmission Output CircuitThe VCO output is amplified by a high-frequency
amplifi er (Q101, Q103 and Q104), passes through a high-frequency antenna switch, passes through a low-pass fi lter and goes to the antenna.
The transmission output is about 1.5W with 3.8V DC supply at battery terminal.
■ Low-Pass Filter CircuitA three-stage Chebyshev type low-pass fi lter is located
between the antenna and transmit/receive switching circuit. It removes harmonic components contained in the transmission output.

CIRCUIT DESCRIPTION
TK-3230

PLL System
■ VCO CircuitThe VCO is housed in a shield case.The VCO circuit consists of a transistor (Q2), a variable
capacity diode (D2) for frequency control, a variable capacity diode (D4) for modulation, transmit/receive frequency shift diode (D1), control transistor (Q1), variable capacitor (TC1) for PLL lock voltage control, and oscillator buffer amplifi er (Q5).
In receive mode, the shift signal T/R goes low, Q1 turns off, and the shift diode (D1) not contact. Q2 produces the first local frequency for reception. (Receive channel frequency – 38.85MHz)
In transmit mode, the shift signal T/R goes high, Q1 turns on and D1 does conducts. Q2 produces about 460~470MHz and the VCO frequency equals the transmit channel frequency.
The 3.0V circuit voltage is produced by ripple removing fi lter circuit Q4.
■ PLL CircuitFrequency data is sent to the PLL IC (IC1) from the MCU
(IC403) 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 6.25kHz/5kHz PLL comparison frequency in the PLL IC.
This PLL IC can generate a channel step which is twice of the PLL comparison frequency. Hence, the PLL IC can directly generate channel step by 12.5kHz/10kHz. Beside, an external control voltage of TCXO is used to shift TCXO reference frequency by 6.25kHz/5kHz to achive channel step with 6.25kHz/5kHz generate in the PLL IC.
The VCO output is divided by the divide ratio set by the divider in the PLL IC to generate 6.25kHz/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 fi lter 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).
■ Unlock Detection CircuitIf 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 MCU to inhibit transmission when the PLL is unlocked.

Control System
■ Reset CircuitWhen a battery voltage is dropped, IC401 is detected
low voltage, and this detected signal input to IC403 for stop the MCU function. IC400 is detected the reset voltage.
■ Battery Voltage Detection CircuitThe 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 MCU, and converted to a digital signal.
■ Power Supply CircuitThe power supply voltage is maintained to 3.0V by the
series regulator (IC404). It is used as MCU power 3M, 3C, 3R and 3T.
The B (battery voltage) is supplied to the RF final transistor Q104.
The t ransmiss ion power 3T is supp l ied to the transmission output circuit when the MCU turns Q404 on only in transmit mode.
The reception power 3R is provided to the receive and IF circuits when the MCU turns Q406 on only in receive mode.
The transmission/reception power 3C is supplied to the VCO and PLL circuits when the MCU turns Q405 on in transmit and receive modes.
If no signal is received for 10 seconds, the MCU 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 MCU to save the battery power.
■ QT/DQT
• Encode (Transmit)QT/DQT signal is generated by MCU (IC403). Output
signal (IC403 pin 18 (TO)) goes to TCXO modulation and VCO modulation (Through the VR300).
• Decode (Receive)Detected AF signal go to IC300 and then IC301. Function
of IC301 is LPF for sub-audible frequency. This signal goes to IC403 pin 77 (TI). IC403 is detected the QT or DQT.

ANT cable
■ Battery jig (W05-1365-00)Connect the power cable properly between the battery
jig installed in the transceiver and the power supply, and be sure output voltage and the power supply polarity prior to switching the power supply ON, otherwise over voltage and reverse connection may damage the transceiver, or the power supply or both.
Note: When using the battery jig, you must measure the voltage at the terminals of the battery jig. Otherwise, a slight voltage drop may occur within the power cable, between the power supply and the battery jig, especially while the transceiver transmits.
