CIRCUIT DESCRIPTION

■ IF Amplifier

Frequency Configuration

The first IF signal is amplified by Q351, and the enters

IC321 (FM processing IC). The signal is heterodyned again

with a second local oscillator signal within IC321 to create a

450kHz second IF signal. The second IF signal is then fed

through a 450kHz ceramic filter (Wide : CF301, Narrow :

CF302) to further eliminate unwanted signals before it is am-

plified and FM detected in IC321.

The receiver utilizes double conversion. The first IF is

49.95MHz and the second IF is 450kHz. The first local oscil-

lator signal is supplied from the PLL circuit.

The PLL circuit in the transmitter generates the necessary

frequencies. Figure 1 shows the frequencies.

(L357, L356 and varactor diodes : D353, D354). After the

signal is amplified (Q353), the signal is filtered through a band

CIRCUIT DESCRIPTION

■ Wide/Narrow Switching Circuit

■ Squelch Circuit

The Wide port (pin 23) and Narrow port (pin 22) of the CPU

is used to switch between ceramic filters. When the Wide

port is high, the ceramic filter SW diodes (D332, D331) cause

CF301 to turn on to receive a Wide signal.

The detection output from the FM IF IC (IC321) passes

through a noise amplifier (Q301) to detect noise. A voltage is

applied to the CPU (IC101). The CPU controls squelch ac-

cording to the voltage (SQIN) level. The signal from the RSSI

pin of IC321 is monitored. The electric field strength of the

receive signal can be known before the SQIN voltage is input

to the CPU, and the scan stop speed is improved.

When the Narrow port is high, the ceramic filter SW di-

odes (D332, D331) cause CF302 to turn on to receive a Nar-

row signal.

Narrow

IC101 22pin

The frequency step of the PLL circuit is 5 or 6.25kHz. A

16.8MHz reference oscillator signal is divided at IC401 by a

fixed counter to produce the 5 or 6.25kHz reference fre-

quency. The voltage controlled oscillator (VCO) output signal

is buffer amplified by Q446, then divided in IC401 by a dual-

module programmable counter. The divided signal is com-

pared in phase with the 5 or 6.25kHz reference signal in the

phase comparator in IC401. The output signal from the

phase comparator is filtered through a low-pass filter and

passed to the VCO to control the oscillator frequency. (See

Fig. 6)

Fig. 3 Wide/Narrow switching circuit

■ AF Signal System

The detection signal from IF IC (IC321) goes to D/A con-

verter (IC201) to adjust the gain and is output to AQUA IC

(IC241) for characterizing the signal. The AF signal output

from IC241 and the DTMF/MSK signal, BEEP signal are

summed and the resulting signal goes to the D/A converter

(IC201). The AFO output level is adjusted by the D/A con-

verter. The signal output from the D/A converter is input to

the audio power amplifier (IC281). The AF signal from IC281

switches between the internal speaker and speaker jack (J1)

output.

■ VCO

The operating frequency is generated by Q444 in transmit

mode and Q441 in receive mode. The oscillator frequency is

controlled by applying the VCO control voltage, obtained

from the phase comparator, to the varactor diodes (D443 and

D444 in transmit mode and D441 and D442 in receive mode).

The TX/RX pin is set low in receive mode causing Q443 and

Q442 to turn Q444 off, and turn Q441 on. The TX/RX pin is

set high in transmit mode. The outputs from Q441 and Q444

are amplified by Q446 and sent to the RF amplifiers.

CIRCUIT DESCRIPTION

■ Unlock Circuit

Transmitter System

■ Outline

The transmitter circuit produces and amplifies the desired

frequency directly. It FM-modulates the carrier signal by

means of a varicap diode.

During reception, the 8RC signal goes high, the 8TC signal

goes low, and Q44 turns on. Q43 turns on and a voltage is

applied to the collector (8R). During transmission, the 8RC

signal goes low, the 8TC signal goes high and Q46 turns on.

Q45 turns on and a voltage is applied to 8T.

The CPU in the control unit monitors the PLL (IC401) LD

signal directly. When the PLL is unlocked during transmis-

sion, the PLL LD signal goes low. The CPU detects this sig-

nal and makes the 8TC signal low. When the 8TC signal goes

low, no voltage is applied to 8T, and no signal is transmitted.

■ Power Amplifier Circuit

The transmit output signal from the VCO passes through

the transmission/reception selection diode (D448) and ampli-

fied by Q501, Q502 and Q503. The amplified signal goes to

the final amplifier (Q504) through a low-pass filter. The low-

pass filter removes unwanted high-frequency harmonic com-

ponents, and the resulting signal is goes the antenna termi-

nal.

Q43

Q45

■ APC Circuit

Q44

Q46

The automatic transmission power control (APC) circuit

detects part of a final amplifier output with a diode (D606,

D607 and D608) and applies a voltage to IC651. IC651 com-

pares the APC control voltage (PC) generated by the D/A con-

verter (IC201) and DC amplifier (IC214) with the detection

output voltage. IC651 generates the voltage to control Q502,

Q503 and Q504 and stabilizes transmission output.

The APC circuit is configured to protect over current of

Q502, Q503 and Q504 due to fluctuations of the load at the

antenna end and to stabilize transmission output at voltage

and temperature variations.

CIRCUIT DESCRIPTION

■ Key Matrix Circuit

Control Circuit

The TK-7160 front panel has function keys. Each of them

is connected to a cross point of a matrix of the KMI1 to KMO3

ports of the IC1 LCD driver. The KMO1 to KMO3 ports are

always high, while the KMI1 to KMI3 ports are always low.

The microprocessor monitors the status of the KMI1 to

KMO3 ports. If the state of one of the ports changes, the

microprocessor assumes that the key at the matrix point cor-

responding to that port has been pressed.

The CPU carries out the following tasks:

1) Controls the WIDE, NARROW, TX/RX outputs.

2) Controls the AQUA IC (IC241).

3) Controls the PLL (IC401).

4) Controls the D/A converter (IC201) and adjusts the vol-

ume, modulation and transmission power.

■ Memory Circuit

The transceiver has an 64k-bit EEPROM (IC81). The

EEPROM contains adjustment data. The CPU (IC101) con-

trols the EEPROM through three serial data lines.

■ Encode

The QT and DQT signals are output from QT/DQT of the

CPU (IC101) and summed with the external pin DI line by the

AQUA IC (IC241) and the resulting signal goes to the D/A con-

verter (IC201). The DTMF signal is output from DTMF of the

CPU and goes to the D/A converter (IC201). The signal is

summed with a MIC signal by the AQUA IC (IC241), and the

resulting signal goes to the D/A converter (IC201).

The D/A converter (IC201) adjusts the MO level and the

balance between the MO and QT/DQT levels. Part of a QT/

DQT signal is summed with MO and the resulting signal goes

to the VCOMOD pin of the VCO. This signal is applied to a

varicap diode in the VCO for direct FM modulation.

EEPWP

■ Display Circuit

The CPU (IC101) controls the display LCD and LEDs.

When power is on, the CPU will use the MBL line to control

the LCD illumination and key backlight LEDs.

The dimmer function is controlled by the switch Q1. The

LCD controller (IC1) controls the functions of the LCD

through the DO, CE, CL, DI lines from the CPU.

CIRCUIT DESCRIPTION

■ Decode

Power Supply Circuit

The signal goes to EXTLIMIN (pin 5) of AQUA IC (IC241).

When the power switch on the display unit is pressed, the

power port on the display unit which is connected port 17

(POWER), goes low, then port 78 (SBC) goes high, Q42 turns

on, SB SW (Q41) turns on and power (SB) is supplied to the

radio.

The QT/DQT signal will pass through the low-pass filters in

the AQUA IC (IC241) and be decoded within the AQUA IC

(IC241). The DTMF signal will be decoded within the AQUA

IC (IC241).

When the DC power supplied to the radio, the voltage

regulator IC (IC43) supply into the CPU VDD and reset voltage

detect IC (IC44). IC44 will generate signal (RESET) in to the

reset terminal on the CPU (IC101) to carry out a power ON

reset. Also, CPU (IC101) is checking on port 91 (BATT). If DC

power is less than about 9.5V, the radio is unable to power

on.

IC241

AQUA IC

EXTLIMIN

Fig. 15 Decode

When the DC power voltage deceases from normal volt-

age, the INT voltage detector IC (IC45) will set to high on CPU

port 18 (INT) if B line will became less than about 9.5V. Then

CPU send to EEPROM (IC81) the backup data and go into

STOP mode.

This circuit has an overvoltage protection circuit. If a DC

voltage of 16V or higher is applied to the base of Q81, this

voltage turns Q81 on and sets port 18 (INT) to low. As a

result port 78 (SBC) is low, and turns Q42 and Q41 (SB) off.

■ D/A Converter

The D/A converter (IC201) is used to adjust MO modula-

tion, AF volume, TV voltage, FC reference voltage, and PC

POWER CONTROL voltage level.

Adjustment values are sent from the CPU as serial data.

The D/A converter has a resolution of 256 and the following

relationship is valid:

D/A output = (Vin – VDAref) / 256 x n + VDAref

Vin: Analog input

VDAref: D/A reference voltage

n: Serial data value from the microprocessor (CPU)

4. Connect 50Ω load at the ANT location.

If normal power is not obtained, please follow the

step below

Open the shielding cover (upper), and screw 3 locations

around ANT pin.

Transmit and check current drain at High power mode.

If the current drain is less than 1A, then Final FET is bro-

ken.

If the current drain is less than 5.0A, short the Drive FET

gate to ground, and check the current drain.

If the current drain is not 0.1A less than the original value,

then the Drive FET is broken.

1. Switch off the transceiver.

Impedance of Final FET (Q504) and Drive FET (Q503) can

be measured easily using DVM Ω mode.

Normal condition – Gate : 20kΩ~50kΩ, Drain : 1MΩ~2MΩ

The above impedance values are rough estimations.

2. Switch on the transceiver. Check the voltage at F501 out-

put point.

5. Check input power level at Drive FET gate location.

Connect the wire to [RF] location.

Transmit and check for power to be within the range of

0.3W~0.6W.

If power found is less than 0.3W, check the circuit before

the Drive FET.

The voltage is around 13.6V in receiving condition. The

voltage will be 12.6V~ in transmitting condition. If found

0V at this point then F501 is broken.

3. Remove R517.
