Function and Explanation
Equivalent circuit
1
OSC base
(bypass)
2.9
Internal oscillator consists in balance
amplifier. 2 pin and 3 pin should be
externally equipped with tank resonator
circuit in order to oscillate with feedback
loop.

(coupling)
5.0
4VCC
5.0
Supply voltage pin for the IC.
5
IF output
PC2721
2.9
In
PC2721, 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.
PC2721
PC2722
5.0
In
PC2722, IF amplifier is designed as
balance amplifier.
This pin is assigned for the open collector
output with high impedance dependent on
external inductance.
PC2722
6
GND
0.0
GND pin for the IC.
7
RF input 2
(bypass)
2.4
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 1
2.4
1 pin should be grounded through
coupling capacitor to 0.5 pF.
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.
