Abstract

In this letter, a novel design of X-band rectangular waveguide bidirectional coupler is presented. Through the conversion of coaxial-rectangular waveguide, ladder loading of waveguide and waveguide coupling, the effective methods of matching and coupling are well-improved. This bidirectional coupler has good performance: the directivity is more than 25 dB and the coupling coefficient is 35dB with the deviation of 1 dB from 8.8GHz to 9.9GHz. It can detect a signal of 3KW which is used in high-power microwave measurement system.

一种x波段大功率矩形波导双向耦合器的设计
本文提出了一种新型的x波段矩形波导双向耦合器。通过同轴-矩形波导的转换、波导阶梯加载和波导耦合，改进了有效的匹配和耦合方法。该双向耦合器具有良好的性能:指向性大于25 dB，耦合系数为35dB，从8.8GHz到9.9GHz的偏差为1 dB。它可以检测到3KW的信号，用于大功率微波测量系统。
