Miniaturized multichannel 5G anti-interference filter

Abstract

The invention discloses a miniaturized multi-channel 5G anti-interference filter. The invention relates to the technical field of microwave communication. The miniaturized multi-channel 5G anti-interference filter comprises a first cavity and a second cavity, the first cavity and the second cavity are each divided into four cavities through partition plates. Resonant columns in the cavity adopt alinear arrangement structure. Index requirements can be met only through nine stages of resonance columns, due to the fact that a new topological structure is adopted, the size of the cavity is reduced, the number of the resonance columns in the cavity is reduced, the upper cover and the lower cover of the cavity are separated and can share one set of mold to be machined, and each cavity integrates access of four paths of antenna feeder networks and forms an independent unit. After the first cavity and a second cavity are assembled, the capacity expansion capability of the product is improved,the access of an antenna feeder network of eight channels can be realized at the same time, the size of the product is reduced, and the base station space required by installation is greatly saved; and the product is provided with eight signal input ports and eight signal output ports, matching of most base station control tower communication equipment can be met, and requirements can be met onlyby installing one filter on each control tower.

Description

technical field [0001] The invention relates to the field of microwave communication technology, in particular to a miniaturized multi-channel 5G anti-jamming filter. Background technique [0002] With the advent of the 5G era, the trend of multi-system integration and shared base station transmission is becoming more and more popular. In order to improve the network coverage of mobile communications, improve communication capabilities and reduce waste of resources, many operators currently choose to share base station towers and co-site construction. The method is to set up their own communication equipment; due to the choice of co-site construction, the frequency bandwidth intervals of the communication equipment of each operator are relatively close, resulting in serious interference of communication signals between each other, which seriously affects the communication quality. In order to reduce interference, the traditional way to reduce interference is that each operat...

Problems solved by technology

[0007] In view of the problems existing in the prior art, the purpose of the present invention is to provide a miniaturized multi-channel 5G anti-interference filter, in order to solve the problem that the traditional filter cannot be expanded to access the multi-channel antenna feeder communication system, and the co-construction base station cannot be installed. Reduce product volume, reduce the number of resonant columns in the cavity, reduce manual assembly of resonant columns and welding tapped resonant columns, increase product communication quality, improve communication signal stability, improve production efficiency, reduce production costs, and improve product installation methods
