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.
