Abstract

The invention relates to the technical field of communication device components and in particular to a dielectric for 5G communication, a dielectric waveguide filter, a radiofrequency module, and a base station. The dielectric comprises a plurality of combined dielectric bodies. The surfaces of the dielectric bodies are covered with conductive layers. Each dielectric body comprises a plurality ofarranged resonance portions, and is provided with a coupling window, an input interface and an output interface. The conductive layer is not arranged at the position where coupling window is located.The input interface and the output interface are disposed on different resonance portions of the same dielectric body. At least one isolation portion is arranged between the resonance portion where the input interface is located and the resonance portion where the output interface is located, and causes the coupling bandwidth between the two resonance portions connected thereto to be less than 10%of the operating bandwidth of the dielectric waveguide filter using the dielectric. The dielectric for 5G communication provided by the invention can solve the complicated assembly, high production cost and inconvenient system integration of the existing dielectric waveguide filter.

Description

technical field [0001] The invention relates to communication equipment components, in particular to a dielectric body, a dielectric waveguide filter, a radio frequency module and a base station for 5G communication. Background technique [0002] Compared with the traditional metal cavity waveguide filter, the dielectric waveguide filter has the advantages of small size, small insertion loss, high power withstand, and low cost, which can meet the filter requirements in the 5G communication system. [0003] In the prior art, the two resonators that are not coupled are usually physically separated, which will lead to a large number of types and quantities of dielectric bodies. The production of dielectric waveguide filters requires very high accuracy for the assembly and debugging of dielectric bodies. , once there is a deviation in the position or alignment of the dielectric body, it will have a huge impact on the performance of the entire dielectric waveguide filter. Therefo...
