Abstract: Resonant cavity filters include a conductive housing having a floor. A dielectric resonator is mounted to extend upwardly from the floor. The dielectric resonator has a cylindrical body with a longitudinal bore that defines an inner sidewall. The longitudinal bore has a variable transverse cross-sectional area. A threaded dielectric fastener is at least partially inserted within the longitudinal bore of the cylindrical body.

Abstract: 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.

Abstract: A resonant cavity filter includes a housing having a resonator therein, and a tuning element including an elongated pin member having a conductive outer surface. The tuning element is mounted for insertion of the elongated pin member into an interior of the resonator. The conductive outer surface includes a contact portion by which the elongated pin member is secured in a desired position to adjust a frequency response of the resonant cavity filter, where the contact portion is free of threading.

Abstract: The invention is a compact three-port signal combiner suitable for use in a base station having two different wireless systems. The combiner is designed as a four-port network, but one of the ports is terminated with a predetermined load, thus leaving three ports for connection to user equipment. A first port (A) receives from an antenna a first input signal comprising first and second receive bands and transmits to the antenna a first output signal comprising a transmit band. A second port (R), connected to the first wireless system, outputs to the first wireless system a second output signal comprising the first and second receive bands. A third port (T\R) outputs, to the second wireless system, a third output signal comprising the first and second receive bands and receives from the second wireless system a second input signal that is to be transmitted from the first port.
