ABSTRACT:
An RF switch circuit includes a waveguide transmission line having an input port, an output port, a first wall having a first cavity disposed therein and a second wall having a second cavity disposed therein with the first and second cavities being aligned along a centerline of the waveguide transmission line and means for providing a substantially short circuit impedance characteristic between the first cavity and the waveguide transmission line to RF signals propagating along the waveguide transmission line. The circuit further includes an electrically conductive member disposed in a first region of the second cavity, a diode having a first electrode disposed on a first surface of the electrically conductive member and an electrically conductive post having a first end disposed in the first cavity and having a second end disposed in the second cavity with the second end of the post electrically contacting a second electrode of the diode.
