摘要
为满足新一代电子对抗装备对跨频带超宽带行波管的需求,本文针对4~18 GHz超宽带大功率行波管输能系统开展了匹配优化设计和功率容量分析研究。从同轴窗、同轴输能结构及输能结构与高频结构匹配等几方面综合优化,设计出输入驻波比优于1.53、输出驻波比优于1.55的输能系统,与测试结果对比表明设计方法合理,输能系统和器件匹配成功;针对输出系统的功率容限问题,从峰值功率和平均功率两方面分析了输能窗的电可靠性和热可靠性,制管实测结果表明,该输能系统能够满足行波管应用要求。
In order to meet the requirements of new generation of electronic warfare equipment for cross-band ultra-wideband TWTs,the matching optimization design and power capacity analysis of the energy transmission system of 4~18 GHz ultra-wideband high-power TWT are carried out.The energy transmission system with input standing wave ratio better than 1.53 and output standing wave ratio better than 1.55 is designed through the comprehensive optimization of coaxial window,coaxial energy transmission structure and the matching between energy transmission structure and high-frequency structure.The test result shows that the design method is reasonable and the energy transmission system matches well with the device.Aiming at the power tolerance of the output system,the electrical reliability and thermal reliability of the energy transmission window are analyzed from the aspects of peak power and average power.The experimental results show that the energy transmission system can meet the application requirements of TWTs.
