| 摘 要： | 本文提出了一种新型毫米波波导开关－激光控制的半导体加载波导开关。这种开关具有插入损耗小，开关动态范围大，单模带宽宽，响应速度快等优点，同时，还提出了“有耗介质盘”的概念，从理论上对这种开关特性进行了分析，理论与实验吻合较好，预计，这种结构在高功率系统中有潜在应用前景。

| Abstract: | In this paper,a kind of laser-controlled semiconductor-loaded E-plane waveguide switch has been presented. The on/off ratios and insertion losses are given under laser illumination.The on/off ratio reaches 38. 5dB,the front fringe time of the switch is about 0.05ms,and the insertion loss is only 0. 16 dB at frequency 37.1GHz. One simple method to analyze its behaviors, which is in good agreement with the experimental results,has been introduced. It shows that such switch can be applied in high power millimeter-wave system. |
