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(8mm全波段均小于0.5dB)、开关动态范围大(达40dB以上)、单模带宽宽、响应速度快(约0.05μs)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的应用前景。
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.
