ABSTRACT:
Internal to the transistor, an additional, direct connection is made from the internal collector to the external collector of the transistor by a fixed shunt inductance. The external power supply V.sub.s is applied to the transistor collector through an adjustable external shunt element. The adjustable external shunt element allows the user to finetune the impedance matching circuit such that the transformation ratio of the output matching circuitry is minimized.
