Description
Technical field
The utility model relates to wave filter technology field, particularly relates to a kind of low-loss height intermodulation 4G filter.
Background technology
Existing 4G filter shape size is large, and indoor design is complicated, and loss is large, processing difficulties, and the slow capacity of debugging speed is little, and unsightly, Signal transmissions is obstructed in design, and installation and maintenance are inconvenient, therefore need the 4G filter of a kind of low-loss height intermodulation.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of low-loss height intermodulation 4G filter.
The utility model is achieved through the following technical solutions:
A kind of low-loss height intermodulation 4G filter, include resonant cavity, plating silver layer in resonant cavity, the control element of five high-power tuning capacitances adopting windowing mode to be coupled and a band stray signal is provided with in resonant cavity, five described high-power tuning capacitances divide two row arrangements, up two are positioned at directly over descending three, two the high-power tuning capacitances being positioned at the leftmost side and the rightmost side are connected to signal input line and output line, signal input port SMA-KFD connector and signal output port SMA-KFD connector is respectively equipped with at the left and right sides of resonant cavity, described signal input line and output line are connected with signal input port SMA-KFD connector and signal output port SMA-KFD connector respectively, resonant cavity is fixed with cover plate.
At described lid surface plating silver layer.
Resonant cavity is mainly used to transmit the signal and the every required technical indicator of product that produce between each frequency, and be a kind of microwave transmission line, the electric energy produced when powering up work and magnetic energy are stored at inside, chamber.
The utility model has the advantages that: the utility model is mainly used in gsm system receiving and transmitting signal filtering device in mobile communication 4G network, can realize will the gsm system signal transmitting and receiving of extensive use simultaneously, not only can work as single filtration module use but also can work as duplexer use, have that loss is little, overall dimensions are little, be designed beautifully, the special defeated plurality of advantages such as unobstructed, convenient for installation and maintenance of signal.
