Abstract
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.
