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.
