返波激励的级联折叠波导行波放大器
Cascade folded waveguide traveling-wave tube amplifier driven by backward-wave
摘要
利用折叠波导返波振荡器(FW-BWO)作为激励源, 用于激励工作频率为216 GHz的折叠波导行波放大器。利用3D-Magic进行仿真实验, 通过仿真优化, 最终得到96 W的输出功率, 整个电路的长度被设计为只有1 cm左右。通过该方法, 显著地缩短了高频结构长度, 有利于实现小型化的真空电子学太赫兹源, 对集成化的太赫兹源设计具有重要的参考价值。
Abstract
A folded waveguide traveling-wave tube (FW-TWT) amplifier which is driven by backward-wave has been studied in this paper. Folded waveguide backward oscillator (FW-BWO) is used as driven source and drives the traveling-wave tube amplifier. The working frequency of FW-BWO is 216GHz. The optimized results were simulated by 3D-Magic. By optimizing the length and height of the loss-material and the current of cathode, the output power of the FW-TWT is 96W. The length of the waveguide is only about one centimeter.
