output impedance of anti-75 Q, the collector and the base of VT2 vri pole power supply is provided through 4 short high impedance microstrip line: transistor base-emitter bias press consists of two parts: one is self-emitter voltage of the transistor, the other part is fed from an external voltage pole group. +15 V power supply is made by the high impedance IF output cable isolation inductor microstrip line fed.
