Internal oscillator consists of a
balance amplifier. Pin 2 and pin 3
should be externally equipped with a
tank resonator circuit in order to
oscillate with feedback loop.
Pin 1 should be grounded through
coupling capacitor ~0.5 pF.
Pin 3 is an open collector. This pin should
be coupled through resistor or choke coil
in order to adjust Q and connect the
supply voltage.
Supply voltage pin for the IC.
In the UPC2721 the amplifier is designed
as single-ended push-pull amplifier. This
pin is an emitter follower output with a
wideband 50
impedance.
In the UPC2722 the IF amplifier is
designed as a balanced amplifier. This pin
is an open collector output with high
impedance dependent on external
inductance.
Pin 7 and pin 8 are inputs to a double-
balanced mixer. Either pin can be
assigned for input or ground.
GND pin for the IC.
