| 摘 要： | 为了抑制W波段折叠波导行波管研制中的自激振荡，保证行波管正常放大工作，分析了折叠波导慢波结构中反射振荡、返波振荡和带边振荡的产生原因，开展了折叠波导行波管振荡抑制技术研究，通过优化设计和工艺研究采用周期跳变作为关键技术用于W波段折叠波导行波管的研制。通过模拟检验和实验验证，证明采用了振荡抑制技术后行波管自激振荡得到了有效的抑制，W波段脉冲行波管在20%占空比时脉冲输出功率大于100 W，带宽大于5 GHz。

| Abstract: | In order to suppress oscillation and maintain stability in the development of W-band folded waveguide traveling wave tube, this paper presents the analysis of reflection, backward wave and band edge oscillations. Periodic step structure together with other design and fabrication research improvement was applied to increasing the oscillation threshold. The investigation on oscillation suppression for W-band folded waveguide was carried out by simulation and experiment. After the methods mentioned above were applied as the most important key technologies to improving the output power and broadening the bandwidth, the developed W-band folded waveguide traveling wave tube could maintain stability from possible oscillations and reach over 100 W output power with 5 GHz bandwidth at 20% duty cycle. |
