Abstract

The invention discloses a C-band coupler with shielded wires; through the three-segment coupling section distribution on the PCB, the problem of large interference of the traditional C-band bridge is effectively solved; in addition, because the coupling line is printed on the The PCB board is coupled through the insulating layer of the PCB board to realize integrated production, thereby realizing batch and simplified production, and improving the working frequency bandwidth, making it low loss and stable high and low temperature performance.

Description

Technical field [0001] The invention relates to a C-band coupler with shielded wire. Background technique [0002] The main structure of the C-band coupler is the shell and the built-in C-band bridge. At present, the existing C-band coupler is generally designed with electronic circuits. The wiring is complicated, the manufacturing is difficult, and the wiring is easy to make mistakes. When reducing the size, there are still shortcomings such as frequency mutual interference, and its electrical performance needs to be improved, such as narrow working bandwidth, large loss, unstable high and low temperature performance, etc., and there are also low processing accuracy, poor mass production consistency, Problems such as large size and heavy weight cannot meet the increasing requirements of broadband applications. Summary of the invention [0003] The invention aims to solve the technical problems of the traditional C-band coupler, such as narrow working bandwidth, large loss, unsta...
