Abstract
A plurality of contiguous cavity pairs of multipactor input and output cavities respectively formed in two opposing ridge waveguide sections and which are mutually separated by an acceleration drift region of relatively high DC electric field strength. Both waveguide sections include means such as an RF window at one end for coupling RF power in and out of the sections while the other end is suitably terminated and additionally provides the structure which can be placed under a vacuum to properly function. The cavity pairs are arranged in a linear array subassembly within each of the waveguides and are designed to have a broadband frequency response by progressively increasing in frequency so that half power points of contiguous cavity pairs are in close proximity.

An electronic device operable in the microwave millimeter wave frequency range comprising, in combination:
- microwave/millimeter wave transmission means;
- an array of closly spaced multipactor cavity pairs consisting of input cavities and output cavities arranged in opposed relationship on opposite sides of a DC electric field region coextending longitudinally with said transmission line means;
- aligned apertures connecting each cavity pair to said DC electric field region;
- an input RF coupling iris and an outut RF coupling iris operably disposed on each of said cavity pairs;
- each cavity pair tuned to a respective resonant frequency corresponding to its said input and output coupling irises, the respective resonent frequencies of the cavity pairs varying from pair to pair in the array along said transmission line means.
