Abstract: Embodiments relate to the field of technologies of components of communications devices, and provide a dielectric filter, which resolves a problem that a solid dielectric filter has a difficulty in implementing capacitive coupling. The dielectric filter includes at least two dielectric resonators, where each of the dielectric resonators includes a body made of a solid-state dielectric material, and an adjusting hole located on a surface of the body. The adjusting hole is a blind hole, configured to adjust a resonance frequency of the dielectric resonator on which the blind hole is located. The bodies of all the dielectric resonators included by the dielectric filter form a body of the dielectric filter.

Abstract: The present application provides a dielectric resonator, a dielectric filter, a base station and a method for fabricating the dielectric resonator or the dielectric filter. The dielectric resonator includes: a solid dielectric resonator body, a blind hole located on one side of the solid dielectric resonator body, a metalized layer covering both a surface of the solid dielectric resonator body and a surface of the blind hole, and a demetallized notch located at the metalized layer on the surface of the blind hole. The dielectric resonator provided in the present application can implement tuning of the dielectric resonator, and reduce impact on the resonance frequency of the dielectric resonator after the dielectric resonator is tuned, where the impact caused by that the demetallized notch is covered by a metal material in an assembly process of the dielectric resonator, and signal energy that is leaked from the notch is reduced.

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.
