Abstract:
A millimeter wave oscillator has a case of block construction defining a waveguide passageway with a waveguide flange at the output end integral with the case. A plunger with a half-round surface facing the open end is disposed adjacent a wafer-like disc and a source diode has a terminal which is contacted by the disc. The diode is adjustably disposed in the case. The disc is disposed on the end of a piston slideably disposed in a capacitor body which is coupled to a source of DC bias. A spring in the body urges the disc into contact with the diode. Stubs are provided for impedance matching of the following circuit.
