Title: DIELECTRIC FILTER, TRANSCEIVER AND BASE STATION
Abstract:
The embodiments of the present invention provide a dielectric filter, which relates to the technical field of communication device assemblies and solves the problem that it is difficult for a solid dielectric filter to realize capacitive coupling. The dielectric filter provided in the embodiments of the present invention comprises at least two dielectric resonators, and each dielectric resonator comprises a body made of a solid dielectric material and a debugging hole located on the surface of the body; the bodies of all the dielectric resonators included in the dielectric filter constitute a body of the dielectric filter, and the dielectric filter further comprises: at least one negative coupling hole, wherein each negative coupling hole is located on a position of the surface of the body where two dielectric resonators are connected, and the located position thereof is connected to the two dielectric resonators; and a conducting layer covering the surface of the body of the dielectric filter, the surface of the debugging hole and the surface of the negative coupling hole. The embodiments of the present invention are mainly used for a radio frequency front end of a high-power wireless communication base station.
