Abstract: The present disclosure relates to transverse magnetic wave (TM) mode filters and methods for manufacturing a TM mode filter. One example TM mode filter includes a filter body, a dielectric, and a transition layer, the filter body including a filter cavity and a cover, and having hollow confined space, the dielectric located in the hollow confined space, and the transition layer configured to connect the dielectric and the filter body. A coefficient of thermal expansion (CTE) of the transition layer is between a CTE of the filter body and a CTE of the dielectric.

Abstract: A transverse magnetic (TM) mode dielectric filter includes an enclosure, a dielectric resonator, a main cover, and an elastic component, where the dielectric resonator is disposed in a resonant cavity of the enclosure; the main cover is secured between the elastic component and an open end of the enclosure; the elastic component includes multiple elastic flaps; the multiple elastic flaps are evenly distributed around an axial direction of the dielectric resonator; one end of each of the elastic flaps is fixedly connected to the main cover, and free ends of the elastic flaps elastically act on a central part of an outer surface of the main cover, to provide an elastic force towards the dielectric resonator. The evenly distributed multiple elastic flaps produce a pressure towards the dielectric resonator. A uniform and stable pressure is produced around the dielectric resonator, to ensure a uniform current density inside the resonant cavity.
