Abstract

The invention discloses a C-band coupler with a rectangular notch; through the three-segment coupling section distribution on the PCB, it effectively solves the problems of large interference of the traditional C-band bridge; in addition, because it prints the coupling line On the PCB board, it is coupled through the insulating layer of the PCB board to realize integrated production, and then realize batch and simplified production, and improve the working frequency bandwidth, so that its loss is small and its high and low temperature performance is stable.

Description

technical field [0001] The invention relates to a C-band coupler with a rectangular notch. 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 co...
