(T
Supply voltage pin for the IC.
The amplifier is designed as single-ended
push-pull amplifier. This pin is an emitter
follower output with a wideband 50
impedance.
GND pin for the IC.
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.
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 7 and pin 8 are inputs to a double-
balanced mixer. Either pin can be
assigned for input or ground.
Pin 1 should be grounded through
coupling capacitor ~0.5 pF.
