摘要

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.
