2-1. Front End (RF Amplifi er) Circuit
The signal coming from the antenna passes through the
transmit/receive switching diode circuit (D101, D102, D103
and D105) and a BPF (L208 and L210), and is then amplifi ed by the RF amplifi er (Q204).
The resulting signal passes through a BPF (L215, L218
and L219) and goes to the mixer. These BPFs are adjusted
by variable capacitors (D201 D202, and D204). The input
voltage to the variable capacitor is a regulated voltage output from the DAC (IC300)
The signal from the front end is mixed with the fi rst local
oscillator signal generated in the PLL circuit by Q203 to produce a fi rst IF frequency of 38.85 MHz.
The resulting signal passes through the XF200 MCF to
cut the adjacent spurious and provide the optimum characteristics, such as adjacent frequency selectivity.
2-3. IF Amplifi er Circuit
The fi rst IF signal is passed through a four-pole monolithic crystal fi lter (XF200) to remove the adjacent channel
signal.
The fi ltered fi rst IF signal is amplifi ed by the fi rst IF amplifi er (Q202) and then applied to the lF system IC (IC200).
The IF system IC provides a second mixer, second local
oscillator, limiting amplifier, quadrature detector and RSSI
(Received Signal Strength Indicator).The second mixer
mixes the fi rst IF signal with the 38.4MHz of the second local oscillator output (TCXO X1) and produces the second IF
signal of 450kHz.
The second IF signal is passed through the ceramic fi lter
(CF200) to remove the adjacent channel signal. The fi ltered
second IF signal is amplified by the limiting amplifier and
demodulated by the quadrature detector with the ceramic
discriminator (CD200).The demodulated signal is routed to
the audio circuit.
IC305, IC303 and goes to AF amplifi er through IC302.
The signal then goes through an volume control (VR500),
and is routed to an audio power amplifi er (IC302) where it is
amplifi ed and output to the speaker.
To output sounds from the speaker, IC400 sends a high
signal to the SPMUT line and turns IC400 on through Q300,
Q301, Q302 and Q306.
3. T ransmitter System
3-1. Microphone Amplifi er Circuit
The signal from microphone amplifi ed by IC301 and goes
through mute switch (IC300).
IC304 is composed of high-pass fi lter, low-pass fi lter and
pre-emphasis/IDC circuit.
The output signal from the DAC IC (IC300) goes to the
VCO modulation input.

CIRCUIT DESCRIPTION /
3-2. Drive and Final Amplifi er Circuit
The signal from the T/R switch (D100 is on) is amplifi ed
by the pre-drive amplifi er (Q100) to 30mW.
The output of the pre-drive amplifi er is amplifi ed by the
drive amplifi er (Q101) and the RF fi nal amplifi er (Q102) to
4.0W (1W when the power is low).
The drive amplifi er and the RF fi nal amplifi er consist of
two MOS FET stages.
The output of the RF final amplifier is then passed
through the harmonic fi lter (LPF) and antenna switch (D101
and D102) and is applied to the antenna terminal.

4. Frequency Synthesizer Circuit
4-1. Frequency Synthesizer
The frequency synthesizer consists of the TCXO (X1),
VCO, PLL IC (IC1) and buffer amplifi ers.
The TCXO generates 19.2MHz. The frequency stability is
2.5 ppm within the temperature range of –30 to +60°C.
The frequency tuning and modulation of the TCXO are
done to apply a voltage to pin 1 of the TCXO. The output of
the TCXO is applied to pin 1 of the PLL IC.
The VCO consists of 1VCO and covers a dual range of
the 350.00~390.00MHz and the 311.15~351.15MHz. The
VCO generates 311.15~351.15MHz for providing to the fi rst
local signal in receive.
The PLL IC consists of a prescaler, reference divider,
phase comparator, charge pump (The frequency step of the
PLL circuit is 5 or 6.25 kHz).
PLL data is output from DATA (pin 19), CLOCK (pin 18)
and PLDL (pin 20) of the MCU (IC400). The data are input to
the PLL IC when the channel is changed or when transmission is changed to reception and vice versa. A PLL lock condition is always monitored by the pin 22 (PLUL) of the MCU.
When the PLL is unlocked, the PLUL goes low.

The control consists of the MCU (IC400) and its peripheral circuits. It controls the TX-RX unit. IC400 mainly performs
the following;
1) Switching between transmission and reception by PTT
signal input.
2) Reading channel information, frequency, and program
data from the memory circuit.
3) Sending frequency program data to the PLL.
4) Controlling squelch on/off via the DC voltage from the
squelch circuit.
