摘要

我们提出了基于蛇形波导电路的w波段行波管(TWT)的测试，该电路由20kv, 130mA电子枪供电。我们测量了93 GHz时的峰值输出功率为215±2W，饱和增益为20.1±0.15dB，在88-98 GHz范围内，在0.1%占空率下脉冲输出功率>100 W。工作电压为20.8 kV，在91 GHz时产生285±3W，增益为22.4±0.15dB。

Demonstration of a W-band TWT with 10 GHz Bandwidth

We present testing of a W-band traveling-wave tube (TWT) based on a serpentine waveguide circuit, powered by a 20 kV, 130mA electron gun. We measure peak output power of 215±2W at 93 GHz with 20.1±0.15dB saturated gain, and>100 W from 88-98 GHz, pulsed at 0.1% duty. Operating at 20.8 kV, the TWT produces 285±3W at 91 GHz with 22.4±0.15dB gain.
