摘　　要：行波管具有大功率、高增益等优点,是雷达、电子对抗系统等武器装备的核心电子器件。采用一种新型慢波结构——非半圆弯曲变形折叠波导,设计出低电压、高效率、宽带W波段脉冲行波管,工作电压16 kV,电流125 mA,6 GHz带宽内输出功率大于125 W,增益大于34 dB,电子效率与总效率分别大于6.3%,25.7%。Traveling-Wave Tubes(TWTs)feature high output power and gain,and are the core component for radars and electronic countermeasure systems.This paper presents a design for a low voltage,high efficiency W-band pulsed TWT,using a novel type of Folded Waveguides(FWGs)with modified circular bends.The designed TWT,operated at 16 kV and 125 mA,is capable of delivering an output power over 125 W,with electron efficiency and total efficiency over 6.3%and 25.7%respectively,in a frequency range of 91-97 GHz.
