基于高功率的E波段矩形环对角双杆行波管设计
E-band Rectangular-ring Vertex Double-bar Traveling-wave Tube Design Based on the High-power
摘要
Abstract
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).关键词
