一种短波宽带定向耦合器的设计

The Design of a Kind of Broadband Directional Coupler

根据变压器串并联同时耦合的原理 ,提出了一种利用三线变压器魔T和传输线变压器构成定向耦合器的方法 ,给出了设计原理 ,设计制作了一种短波宽频带、大功率定向耦合器。并对其参数进行了理论计算和实际测量 ,测试结果与理论分析吻合 ,满足设计要求。经过实际应用 。

According to the theory of transformer series parallel coupling at the same time, put forward a method that the directional coupler is made of three ply line transformer magic T and transmission line transformer, bring forward the theory of design and devise a kind of wide frequency band and ample power directional coupler. In addition, the paper calculates academic parameter and measure the parameter. By means of the test, the result coincides with the analysis of theory. By practical application, the means of device is doable.
