Abstract:
A quad-mode microwave or RF bandpass filter comprises a housing of a conductive material defining a cylindrical cavity and containing a cylindrical dielectric resonator defined by a parallel pair of face surfaces. The dielectric resonator is held within the housing between a pair of support plates of a dielectric material. Internal coupling elements are provided above and/or below the dielectric resonator for coupling between resonating modes. Further mode coupling elements are protruding into the housing.
