摘　　要：为满足现今社会对高性能行波管日益增长的需求,行波管的高功率、高效率、宽频带是当代电子器件领域的重要发展方向。慢波结构的品质直接关系到行波管的性能。为此,设计了E波段矩形环对角双杆行波管。对矩形环对角双杆慢波结构的加工方法进行了研究,相较于传统的环杆模型,矩形环对角双杆慢波结构与微加工技术有着更好的匹配性,有利于器件的小型化。考虑到理论分析的方法过于复杂,求解存在误差,实验测试的方法成本较高,借助高频电磁仿真软件对矩形环对角双杆慢波结构进行研究,优化了慢波结构尺寸参数以及电气参数。注-波互作用结果表明,在工作电压为16.8 kV,工作电流0.1 A的条件下,矩形环对角双杆行波管在中心工作频点75 GHz处可获得最大输出功率210 W,对应增益和电子效率为34.19 dB和12.5%,3-dB带宽为16 GHz(62~78 GHz)。To meet the growing demand for high-performance traveling wave tubes(TWTs),the high power,high efficiency and wide frequency band of TWTs are important development directions in the field of contemporary electronic devices.The quality of the slow-wave structure(SWS)is directly related to the performance of the TWT.For this,the E-band rectangular ring vertex double-bar(RRVDB)TWT is designed.The processing method of RRVDB SWS is studied.Compared to the traditional ring rod model,the RRVDB SWS has a better match with the micromachining technology,this contributes to the miniaturization of devices.Considering that the method of theoretical analysis is too complex,there are errors in the solution,the cost of experimentally tested methods is high,with the help of high-frequency electromagnetic simulation softwares,the RRVDB SWS is studied,and the size parameters and electrical parameters of the SWS are optimized.Beam-wave interaction results show that under the condition of working voltage of 16.8 kV and working current of 0.1 A,the RRVDB TWT can obtain a maximum output power of 210 W at the central working frequency of 75 GHz,the corresponding gain and electronic efficiency of 34.19 dB and 12.5%,and the 3-dB bandwidth is 16 GHz(62~78 GHz).
