RECEIVER CIRCUITS

3-1-1 RF CIRCUIT (RX UNIT)

Received signals enter the antenna connector (J6) and

pass through a bandpass filter (Cl, C2, C4-C6, C8, L1,

L2). The filtered signals are applied to an RF amplifier

(Ql). The RF amplifier (Ql) employs an FET (3SK121)

which expands the dynamic range with low noise. The

RF signals are applied to a bandpass filter (C14, C15,

C17-C19, C21--C23, C25, L4-L6).

(RX UNIT)

3-1-4 SQUELCH CIRCUIT

(RX AND LOGIC UNITS)

A squelch circuit cuts out AF signals when no RF signal

is received. By detecting noise components in the AF

signals, the squelch circuit switches the AF mute

switches.

Some noise components in the AF signal from IC1 (pin 9)

are applied to an active filter section (IC1, pin 10) via a

de-emphasis circuit (R26, C51-C53). This circuit is

an integrated circuit with frequency characteristics of

-6 dBloctave. The [SQUELCH] control (R2) on the

FRONT PANEL adjusts the IC1 (pin 10) input level.

The 1st mixer circuit converts the received signals to a The active filter section amplifies noise components of

(RX UNIT)

The 2nd mixer circuit converts the 1st IF signal to

a 2nd IF signal. A double superheterodyne system

(which converts receive signals twice) improves the image

rejection ratio and obtains stable receiver gain.

The amplified signal is applied to a 2nd mixer (Q4) and is

then mixed with a 21.345 MHz 2nd LO signal to produce

a 455 kHz 2nd IF signal.

The 455 kHz 2nd IF signal is applied to a ceramic filter

(F12) where unwanted signals are suppressed and then

to a limiter amplifier section in IC1 (pin

5).

TRANSMITTER CIRCUITS

3.2-1 MICROPHONEAMPLIFIER CIRCUIT

(TX

AND T-VCO UNITS)

The AF signal from the microphone is applied to a

microphone amplifier (ICl0, pin 6). The amplified signal

is output from IC10 (pin 7) and applied to lClO (pin 2)

to mix with the "MOD" signal from IC15 on the LOGIC

UNIT. The signal is output from lClO (pin 1) and

applied to a limiter (IC7, pin 3). The AF signal obtains

+6 dBIoctave pre-emphasis at C53 and R51 which

are connectedto pin 2.

The output signal from lC7 (pin 1) is applied to the

splatter filter circuit (IC7, R55, R59, R60, C56, C61, C62)

which attenuates components of frequencies of 3

kHz

and above. IC7 (pin

7)

outputs an "MOD" signal. The

"MOD" signal is applied to the T-VCO UNIT.

3-2-2 MODULATION CIRCUIT (T-VCO UNIT)

The modulation circuit modulates the VCO oscillating

signal (RF signal) using the microphoneaudio signal.

The "MOD" signal from IC7 (pin 7) changes the reactance

of varactor diode (D5) to modulate the oscillated signal

at T-VCO ((21). The oscillated signal is buffer-amplified

at Q2 and is then applied to the drive amplifier circuit.

3-2-3 DRIVE AMPLIFIER CIRCUIT

(TX

AND PA UNITS)

The VCO output is buffer-amplifiedat IC1 and Q2. The

signal is applied to the drive amplifier (Ql) on the PA

UNIT. The drive amplifier (Ql) amplifies the signal to

obtain200 mW.

The control voltage from the APC circuit is applied to the

collector of Ql for stable RF output power from a power

amplifier (ICl).

3-2.4

RF POWER AMPLIFIER (PA UNIT)

lC1 is a power module which provides a stable 25 W

(DC

13.8

V) of output power.

An RF signal from the drive amplifier (Ql) is applied

to IC1 (pin

1).

The amplified signal is output from IC1

(pin 4) and applied to the antenna connector through

the RF detector circuit and low-passfilter circuit.

3-2-5 APC CIRCUIT (PA UNIT)

This circuit controls a current of the power module's first

stage and a current of the driver amplifier to obtain stable

RF output power.

The APC mismatchdetector circuit consists of C14-C17,

02, 03,

L3,

R8 and R9. When the antenna impedance

is matched at 50

i2,

D2 and D3 detect the minimum

voltage. The detected voltage is applied to a differential

amplifier (IC2, pin 6). The APC reference voltage is

applied to lC2 (pin 5).

When the antenna impedance is mismatched, the

voltage in pin 6 of IC2 exceeds the reference voltage in

pin 5 of IC2. The output level from lC2 (pin 7) decreases.

Q2 amplifies the current from the differential amplifier

(IC2) which controls Q3. 03 changes the supply voltage

to Q1 and ICl.

This decreases the output power from the drive amplifier

(Ql) and power amplifier (IC1) until the input voltage in

pin 6 of 1C2 reaches the same levelas pin 5 of IC2.

PLL

CIRCUITS

3-3-1

GENERAL

Each receiver and transmitter circuit has an independent

PLL circuit for controlling frequencies. All PLL circuits

are shielded and installedon the RX and TX UNITS.

PLL circuits steadily oscillate the transmit frequency and

the receive local frequency. The PLL output frequency is

controlled by the divided ratio (N-data) of the program-

mable divider.

3-3-2

RECEIVER PLL CIRCUIT (RX UNIT)

The PLL circuit, using a PLL IC (IC3) and dual modulus

prescaler (IC4) on the RX UNIT, generates the 1st LO

frequency with a Colpitts VCO (Ql) on the R-VCO UNIT.

The PLL IC sets the dividing ratio based on serial data

from the CPU and controls the dual modulus prescaler.

The PLL IC compares the phases of a VCO signal with

the reference oscillator frequency and detects the out-

of-step phase. Then, the VCO signal is output from

the PLL IC (pin 16 and 17).

3.3-4

RECEIVER LOOP FILTER AND DC-DC

CONVERTER CIRCUITS

(RX AND R=DC-DCUNITS)

Phase-detected signals from IC3 (pin 16 and 17) are

converted to DC voltage by a loop filter consisting of an

active filter ((210, Q11).

The frequency at which the VCO oscillates is controlled

by varactor diodes (01-04) on the R-VCO UNIT. DC

voltage (PLL lock voltage) is provided through the

integrator circuit (R32, C110).

The DC-DCconverter circuit (ICl and Ql)on the R-DC-DC

UNIT creates approximately

20

V DC from 5V DC to obtain

wide range lock voltages for the PLL circuits.

3-3-5

RECEIVER VCO CIRCUIT (R-VCO UNIT)

The VCO circuit (Ql, Dl-D4) generates the receive

frequency. Strip lines are used for stable oscillation

over a wide frequency range. Varactor diodes (Dl-D4)

provide frequency control. The buffer amplifier ((22)

protects the PLL output signal from VCO oscillation.

The signal is divided by

64

or

65

in the dual modulus

prescaler (IC4). The phase-dividedsignal is output from

IC4 (pin 5) and applied to the PLL IC (IC3, pin 6).

A

reference frequency is produced by the

oscillator (XI) on the TX UNIT. The frequency is adjusted

with R24. The reference frequency is buffer-amplified

at Q5 and applied to the PLL IC (IC3, pin 2) on the RX

UNIT.
