ABSTRACT:
An output match circuit is coupled between the terminal of a high-frequency device and a ground terminal. The output match circuit includes an LC shunt and an LC notch serially coupled to the LC shunt, wherein the LC notch includes a resonant capacitive element in series with a resonant inductive element. The LC notch may simply include a resonant inductive element coupled directly to the ground terminal. The series inductive element may have a terminal coupled between the resonant capacitive element and the resonant inductive element.
