Abstract

The invention discloses a dielectric filter, which is characterized in that the dielectric filter comprises: a dielectric block, on which at least two dielectric resonators are arranged at intervals, wherein the connection between the two adjacent dielectric resonators is Slots are arranged on the area to define a coupling window between two adjacent dielectric resonators; a dielectric rod is inserted into the slot and contacts with two adjacent dielectric resonators to adjust the adjacent dielectric resonators. The coupling area between two dielectric resonators. With the above structure, the coupling amount of the entire dielectric filter can be adjusted through the setting of the dielectric rod, so that the manufacturer can produce slots and dielectric rods of different specifications according to the different coupling amount of the filter, and can choose to insert in the slot or Without inserting the dielectric rod, the coupling amount of the entire filter can be adjusted. The present application also provides a duplexer and a communication device including the above-mentioned dielectric filter.

Description

technical field [0001] The present invention relates to the technical field of filters, and in particular, to a dielectric filter, a duplexer and a communication device used in a 5G communication system. Background technique [0002] At present, the wireless communication technology is developing rapidly, and the wireless communication system needs a high-performance dielectric filter. The main performance of the dielectric filter is frequency selection and filtering. In the 5G communication system, since the number of transceiver channels has increased from 8 in the original 4G communication system to 64 or even 128, the dielectric filter of the 5G communication system has the characteristics of miniaturization and high performance. The inventor of the present application found in the long-term research and development work that none of the existing filters can adjust the coupling amount. SUMMARY OF THE INVENTION [0003] In order to solve the above problems existing in ...
