ABSTRACT:
A multicavity waveguide filter in which each of the cavities has a pair of orthogonally related modes of propagation. The cavities are positioned side by side with the long axis of each of the cavities being aligned parallel to each other. The cavities are tuned by tuning plungers which are simultaneously moved to predetermined positions within the cavity.
