摘 要: | 设计了一种尺寸紧凑并具有高功率容量的圆波导TE11-TM01模式转换器,结构呈直角转弯形状。该转换器利用传输TE11模式的圆波导与其E面分支耦合进行模式转换,并在TM01输出端口的反向传输短路面加入调配螺钉来拓宽频带。设计结果表明,转换器在工作频率12.7 GHz处的转换效率为99.6%,大于90%的带宽约20%,填充SF6绝缘气体工作时可获得12 MW的功率容量。

Abstract: | This paper presents a compact, high-power mode converter using, which consists of two orthogonal circular waveguides. The mode conversion is based on the coupling relationship of TE11 mode and the TM01 mode transmitting at E-plane branch of the circular waveguide. In addition, wider bandwidth is achieved by placing a tuning screw at the short end. The results show that the conversion efficiency at 12.7 GHz is 99.6% and the bandwidth greater than 90% is ranging from 11 GHz to 14 GHz. |
