The present invention provides a port coupling structure, a filter and a radio frequency component, wherein the port coupling structure is arranged on a dielectric block of a dielectric waveguide resonator, and a first conductive layer is provided on the top surface, the bottom surface and the side surface of the dielectric block, The top surface of the dielectric block is provided with a frequency adjustment structure. The frequency adjustment structure includes a frequency adjustment hole extending from the top surface toward the inside and a second conductive layer arranged on the wall of the frequency adjustment hole. The port coupling structure includes a side surface and is formed by The side faces the inside of the dielectric block and extends to the time delay adjustment hole connected with the frequency adjustment hole, the third conductive layer arranged on the wall of the time delay adjustment hole, and the isolation zone separating the first conductive layer and the third conductive layer. The third conductive layer is connected with the second conductive layer. By connecting the time delay adjustment hole with the frequency adjustment hole, and connecting the time delay adjustment hole with the conductive layer in the frequency adjustment hole, the radio frequency connector is inductively connected with the frequency adjustment hole, thereby realizing a wider coupling bandwidth.
Description
technical field [0001] The invention relates to the technical field of communication radio frequency, in particular to a port coupling structure, a filter and a radio frequency component. Background technique [0002] A filter is a frequency-selective device that is an integral part of communication equipment. With the rapid development of communication systems entering the 5G era, the miniaturization and low insertion loss of devices are the key to the development of communication equipment, and the miniaturization, high performance, and low power consumption filters are the key to the miniaturization of 5G equipment. Waveguide filters have all the characteristics of miniaturization of 5G equipment at the same time, so they have broad application prospects in 5G communication equipment. Therefore, low insertion loss is a focus of research on filter design methods. [0003] However, existing filters can only achieve a relatively narrow coupling bandwidth, and it is often d...
