| 摘 要： | 利用曲折波导慢波结构和一个长宽比为3∶1的带状电子注作为注-波互作用电路，完成了对V波段大功率行波管互作用电路的设计。分析了带状电子注通道对高频特性的影响，并在综合考虑色散和耦合阻抗的情况下得到了优化的结构参数。建立了3维的V波段带状注曲折波导行波管的电路模型，并利用CST粒子工作室完成了注-波互作用的仿真研究。研究结果表明，当工作电压和电流分别为17 kV和150 mA时，带状注曲折波导行波管在58~62 GHz时的饱和平均输出功率大于160 W，增益大于34.7 dB。

| Abstract: | The interaction circuit for the V-band high-power traveling-wave tube (TWT) was designed by employing the folded-waveguide slow-wave structure and a 3∶1 aspect-ratio sheet electron beam as the beam-wave interaction circuit. The effect of the sheet-beam channel on the high frequency properties was analyzed, and the optimized structural parameters were obtained under the consideration of dispersion and impedance. A 3-D circuit model of the sheet-beam folded-waveguide TWT was constructed and the beam-wave interaction of this circuit was simulated using the CST particle studio. From our calculations, the sheet-beam folded-waveguide TWT can produce output power of over 160 W with the gain over 34.7 dB ranging from 58 GHz to 62 GHz, when the cathode voltage and beam current are set to 17 kV and 150 mA respectively. |
