摘要： A resonant cavity filter includes a filter housing defining an internal cavity therein, a resonating element in the internal cavity of the filter housing, and a coupling transmission line extending adjacent a periphery of the resonating element in the internal cavity of the filter housing. The resonating element is rotatable relative to the coupling transmission line to vary an electromagnetic coupling therebetween. Related devices and methods of operation are also discussed.
