Abstract: A half wave dielectric resonator assembly including a resonator cavity having a top surface and a bottom surface, an elongated cylindrical dielectric resonator positioned within said resonator cavity and first and second insulative supports to couple and insulate the ends of the cylindrical dielectric resonator from the resonator cavity. The dielectric resonator has a substantially small diameter to length ratio. The resonator assembly provides improved spurious performance and quality factor (Q) at a lower mass. A resonator filter is constructed using a plurality of these resonator assemblies, where adjacent pairs of said resonator cavities are separated from each other by a common cavity wall. By forming a first iris opening formed within a first common cavity wall and forming a second iris opening formed within a second common cavity wall having a position that is vertically offset from the position of the first iris, it is possible to reduce stray coupling.

Abstract: A microwave filter has a housing defining an inner cavity. A first resonator is positioned in a first portion of the inner cavity. A second resonator is positioned in a second portion of the inner cavity. A third resonator is positioned in a third portion of the inner cavity. The first resonator and the third resonator are cross-coupled via an iris. The second resonator is elongated and is coupled to the first resonator and the third resonator. The resulting microwave filter has a frequency response having a transmission zero in the lower stopband. A high-pass filter is realized without the use of a cross-coupling probe.

Abstract: A microwave filter has a set of irises to couple cavities within the filter. A trifurcated iris comprises a central iris and a pair of peripheral irises. The peripheral irises are configured and oriented to couple a primary mode having a magnetic field in the axial direction of a filter cavity. The central iris is configured and oriented to couple a secondary mode having a magnetic field in the azimuthal direction of the filter cavity. The configuration of the trifurcated iris is further oriented to minimize the influence of higher order signals such as the TE 21X mode. The peripheral iris are oriented at null points of the primary TE 21X mode and the central iris is also located at a null point. An input and an output iris are configured to receive electromagnetic energy in the axial direction of the filter. The input and output irises are oriented to minimize signals in the TE 21X secondary mode and any TM modes.

Abstract: An externally temperature-compensated microwave resonator comprises a microwave resonator and an external temperature compensator. The microwave resonator is a multi-cavity waveguide. The cavities are configured side-by-side and coupled through irises. The external temperature compensator is oriented and configured to effect a change in volume of the cavities when the resonator and compensator undergo a temperature gradient. The compensator deflects a wall portion of the resonator to accordingly counteract a change in volume of the cavity caused by a temperature gradient.
