ABSTRACT:
A tri-mode spherical cavity microwave filter comprising two tandemly disposed generally spherical bodies each of which defines a spherical cavity which supports three identical, mutually orthogonal modes of electromagnetic energy, a cavity coupling aperture connecting the cavities, a plurality of cavity tuning holes, and a plurality of coupling tuning holes. One of the spherical cavities has an input aperture, and another has an output aperture. The cavity tuning holes and coupling tuning holes are adapted to receive cavity tuners and coupling tuners, respectively.
