PIN EXPLANATION
Pin
No.
Symbol
Function and Explanation
Equivalent Circuit
1
OSC base
(bypass)
Internal oscillator consists in balance amplifier.
2 pin and 3 pin should be externally equiped
with tank resonater circuit in order to oscillate
with feedback loop.
2
OSC base
(feedback)
1 pin should be grounded through approximate
10 pF coupling capacitor.
3
OSC

to OSC buffer
4
V
CC
Supply voltage pin for the IC.
5
IF output
IF output pin. IF amplifier is designed as single-
end push-pull amplifier.
This pin is assigned for the emitter follower
output with 50
constant resistive impedance
in wide band.

IF pre
amp.
6
GND
GND pin for the IC.
7
RF input 1
(bypass)
7 pin and 8 pin are inputs for mixer designed as
double balanced type.
Either pin can be assigned for input and another
for ground.
8
RF input 2
V
CC
RF
input
from
OSC
buffer
to IF
amp.
3 pin is defined as open collector. This pin
should be coupled through resistor or
chock coil in order to adjust Q and be
supplied voltage. In case of abnormal
oscillation, adjust its Q lower to stabilize
the operation.
