Abstract

A tunable capacity-loaded rectangular cavity resonator having an inner conductor and a tuning plunger capacitively coupled to and disposed coaxially of the inner conductor is disclosed. The resonant frequency and impedance of the resonator are essentially determined by the inner conductor dimensions. A plurality of these resonators forming a microwave filter are coupled together by means of inductive diaphragms. The slope of the coupling admittance in the tuning range can be chosen by height and width variations of the aperture in the diaphragm with respect to the length of the tuning plunger. Coupling apertures can be provided in all four sides.
