NIVIN

CIRCUIT

DESCRIPTION

RX

Section

The

front

end

unit

is

comprised

of

a

dual

gate

MOS

FET

and

helical

resonator.

The

2-stage

MCF

(Monolithic

Crystal

Filter)

following

the

1st

mixer

Q2

(3SK74)

provides

excellent

2-signal

characteristic

and

high

sensitivity.

The

IF

signal

from

the

MCF

is

divided

and

applied

to

the

SSB

and

FM

circuits.

The

SSB

signal

passes

through

the

NB

(Noise

Blanker)

gate

crystal

filter

(10H2.2SD)

and

is

amplified

by

the

transmit/receive

IF

amplifier.

Q27,

Q28

and

29,

and

is

then

demodulated

into

an

audio

signal

by

the

product

detector.

In

the

NB

circuit,

the

signal

from

the

MCF

passes

through

the

buffer

amplifier

Q6

and

is

fed

to

the

2nd

mixer

Q7.

This

signal

is

converted

455

kHz

and

the

noise

is

amplified

by

two

stages

for

switching

the

NB

gate.

The

NB

is

front

panel

con-

trolled.

In

the

AGC

circuit,

the

signal

from

the

final

IF

stage

is

detected

and

amplified,

and

the

time

constant

is

automatical-

ly

select

according

to

the

mode

of

operation,

FAST

in

CW

mode

and

SLOW

in

SSB

mode.

The

AGC

signal

is

applied

to

the

3-stage

IF

amplifier,

Q27,

28

and

29

(3SK74),

and

the

RF

amplifier

Q1.

The

AGC

voltage

is

also

used

for

meter

indication.

In

the

FM

circuit.

the

signal

from

the

ceramic

filter

CFW-

455E

is

amplified

by

the

IF

amplifier

Q13

(TA7302P).

The

auto

scan

stop

signal

is

applied

to

the

micro-computer

from

the

squelch

circult.

The

detected

AF

signal

is

amplified

by

the

AF

amplifier

Q18,

a

2SC1815(Y).

The

amplified

signal

passes

through

the

LPF

(Low

Pass

Filter)

Q19.

a

2SC1815(Y)

and

is

power-amplified

by

Q26,

(HA1366W)

via

the

AF

GAIN

control

to

drive

the

speaker.

DESCRIPTION

PLL

Unit

(X50-1620-11)

Fig.

shows

a

basic

block

diagram

of

PLL

circuit.

The

signal

from

the

VCO

(Q1,

a

2SK19

(GR))

passes

through

the

buffer

amplifier

formed

by

Q2,

a

2SC1923

(O)

and

O5,

a

3SK74

(L),

and

is

then

mixed

with

the

HET

(Heterodyne)

signal

by

Q13,

a

2SC1923

(O)

to

produce

5.5

~

7.49

MHz

signal.

This

signal

is

amplified

by

Q10,

11

and

Q12,

2SC460

(B)

and

is

frequency-divided

by

Q18

(TC9122P)

according

to

the

BCD

data

(MHz,

100

kHz

and

10

kHz

order)

from

the

control

unit,

to

produce

10

kHz

comparison

signa!.

Simultaneously,

the

10.24

MHz

signal

from

the

RX

unit

is

frequency-divided

to

1/1024

by

Q17

(TC5O082P-GL)

to

produce

10

kHz

reference

signal.

These

signals

are

phase-compared

by

Q16

(TC5081P)

and

fed

to

the

LPF

formed

by

Q8

and

QQ,

and

the

resulting

control

voltage

is

applied

to

the

VCO

vari-cap

tuning

diode.

The

14.2

MHz

VCO

HET

signal

is

generated

by

crystal

oscil-

lator

06,

a

2SC460

(B),

and

is

then

multiplied

9

times

by

D4

(1$S16)

to
