In the paper, the design and simulation of the TEM-TE10 wideband and high-power mode converter (MC) are investigated. The working frequency of the MC is in the frequency range of 4.3–8.8 GHz (68.7% bandwidth). Due to increasing the waveguide cross-section, the probability of the electrical breakdown dramatically reduces. Electrical breakdown may occur at very high-power outputs of the electromagnetic sources. The power-handling capacity of the MC is 2.34 GW, at the centre frequency.

具有 70% 带宽的高功率 TEM 到 TE10 模式转换器

本文研究了TEM-TE10宽带高功率模式转换器(MC)的设计与仿真。MC 的工作频率在 4.3-8.8 GHz 的频率范围内（68.7% 带宽）。由于增加了波导截面，电击穿的可能性显着降低。电击穿可能发生在电磁源的高功率输出处。MC 的功率处理能力为 2.34 GW，在中心频率。
