Abstract: Filters include a housing having an input port and an output port and a plurality of resonant cavities within the housing. Each resonant cavity may include a respective notch resonator. The filter may further include a bandpass filter that includes a plurality of bandpass resonators, the bandpass filter extending between the input port and the output port. The bandpass filter may replace a transmission line that is included in conventional filters.

Abstract: Filter devices that include a movable radio frequency (RF) transmission line are provided. A filter device that includes a movable RF transmission line also includes a plurality of resonators. The movable RF transmission line is configured to move between a first position and a second position relative to the resonators. Electromagnetic coupling between the movable RF transmission line and the resonators is reduced at the second position relative to the first position. Related methods of operating filter devices are also provided.
