Abstract :
L-3 EDD has developed a W-Band TWT with 100 W RF power over 4 GHz of bandwidth around 94 GHz suitable for MPM integration. The TWT employs an aperture grid modulated electron gun with mod-anode current control, a serpentine waveguide interaction circuit, and a single-stage depressed collector. Two TWTs have been built and tested to over 100 W pulsed output power. The first unit has been operated at high duty, producing 65 W CW output power and 75 W average pulsed power with reduced beam current. The TWT is designed for ease of manufacture, and is suitable for MPM integration, relying on conduction cooling and capable of operation to an altitude of 50k feet.
