Title:
DIELECTRIC FILTER, TRANSCEIVER DEVICE, AND BASE STATION
Document Type and Number:
WIPO Patent Application WO/2018/148905
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of filters, and in particular, to a dielectric filter, a transceiver device and a base station. The dielectric filter comprises a dielectric block the surface of which is covered with a metal layer. The dielectric block comprises at least two resonant cavities. A through hole is formed in the dielectric block and is located between adjacent two resonant cavities, and the inner wall of the through hole is covered with a metal layer. At least one opening that is located in the surface of the dielectric block and that surrounds the through hole is provided with a first partition ring. The inner edge of the first partition ring is exposed from the dielectric block along a region defined in a surrounding manner by the inner edge of the first partition ring and the outer edge of the first partition ring. By means of the dielectric filter, the transceiver device and the base station provided in the embodiments of the present invention, a structure for implementing capacitance coupling is simple, and the treatment difficulty of the dielectric filter is reduced.
