Abstract

See full text

A microfabricated RF filter uses a resonant cavity weakly coupled to a transmission line, to attenuate noise sources emitting interference into the RF radiation at the resonant frequency. Radiation at the resonant frequency is leaked into the resonant cavity and build up there, until it is dumped to ground by a switch.
