Abstract
A hybrid-harmonic waveguide filter includes transformer sections at end terminals of the harmonic waveguide filter, a number of corrugations along the length of the waveguide filter, and multiple ridge interconnects that couple the corrugations. By shaping the identical-cross-section ridge interconnects via single-pass wire electrical-discharge machining (EDM), low manufacturing cost is achieved along with continuous broadband rejection of TEn0 modes and an extremely high-power handling capability is observed.
