Abstract

The invention relates to the technical field of communication, in particular to a dielectric filter and a communication base station, wherein the dielectric filter comprises a body, the body is provided with a front surface suitable for facing an antenna structure and a back surface deviating from the antenna structure, and both the front surface and the back surface are provided with a pluralityof resonant cavities. By arranging the plurality of resonant cavities on the front surface and the back surface of the body, the dielectric filter can be installed with the front surface facing upwards and the back surface facing upwards, a filtering function can be realized, the front surface and the back surface do not need to be distinguished during installation, and the installation is facilitated.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dielectric filter and a communication base station. Background technique [0002] A dielectric filter is a microwave filter that uses a dielectric resonator to achieve frequency selection through multi-stage coupling. After entering the 21st century, dielectric filters have gradually moved from laboratories to production lines after long-term accumulation in theory and practice. Due to the advantages of miniaturization, low loss and good temperature characteristics, dielectric filters are widely used in mobile communication and microwave communication systems. It is characterized by low insertion loss, good power resistance and narrow bandwidth, especially suitable for CT1, CT2, 900MHz, 1.8GHz, 2.4GHz, 5.8GHz, portable phones, car phones, wireless headsets, wireless microphones, radio stations, cordless phones and Integrated transceiver duplexer and other cascade coupli...
