The pre- IF amplifier circuit shown is a distributed parameter microstrip circuit . It works in the 950-1 470 MFk frequency band, with an output impedance
of 75 Q. The collector of vri and the base of VT2 are powered by a ^,4 high-resistance microstrip short line:
the bias between the transistor base and emitter
The voltage consists of two parts: one part is the self-generated emitter voltage of the transistor , and the other part is fed from the base by an external voltage . The +15 V supply
is fed from the IF output cable via a high impedance microstrip isolation inductor.
