Abstract

The invention discloses a low-loss high-intermodulation 4G filter. The filter comprises a resonant cavity, wherein a silver layer is electroplated in the resonant cavity, five high-power tuning capacitors coupled in a window opening manner and a control element for out-of-band spurious signals are arranged in the resonant cavity, the five high-power tuning capacitors are arranged in two lines, the two uplink capacitors are located right above the three downlink capacitors, a signal input line and a signal output line are connected onto the two high-power tuning capacitors located on the leftmost and rightmost sides respectively, a signal input port SMA-KFD connector and a signal output port SMA-KFD connector are arranged on left and right sides of the resonant cavity respectively, the signal input line and the signal output line are connected with the signal input port SMA-KFD connector and the signal output port SMA-KFD connector respectively, and a cover plate is fixed on the resonant cavity. The filter has the advantages of low loss, small external dimension, attractive design, smoothness in signal transmission, convenience in mounting and maintenance and the like.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a 4G filter with low loss and high intermodulation. Background technique [0002] The existing 4G filter has large dimensions, complex internal design, large loss, difficult processing, slow debugging speed, small capacity, unsightly design, unsmooth signal transmission, and inconvenient installation and maintenance. Therefore, a low-loss and high-intermodulation filter is required. 4G filter. Contents of the invention [0003] The object of the present invention is to provide a low loss and high intermodulation 4G filter in order to remedy the defects of the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A low-loss high-intermodulation 4G filter, including a resonant cavity, a silver-plated layer in the resonant cavity, five high-power tuning capacitors coupled by opening windows and a control device for ...
