Abstract

The invention discloses a C-waveband coupler with shielded lines. Through three-section-type distribution of coupling sections on a PCB, the problem that a traditional C-waveband electric bridge is large in interference is effectively solved. In addition, due to the fact that coupling lines are printed on the PCB and coupling is realized through an insulating layer of the PCB, integrated production is realized. Thus, mass and simple production is realized; moreover, the working bandwidth is increased, therefore, losses of the coupler are reduced and the high-temperature performance and the low-temperature performance of the coupler are stable.

Description

technical field [0001] The invention relates to a C-band coupler with a 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 couplers are generally designed with electronic circuits. When the size is reduced, there are still shortcomings such as frequency 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 problems such as low processing accuracy, poor batch production consistency, Problems such as large size and heavy weight cannot meet the growing requirements of broadband applications. Contents 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, unstable high and low temperature performance, low processing accuracy, poor consis...
