Experimental results from the MIT 140 GHz quasioptical gyro-TWT

We present the latest experimental results from a novel 140 GHz quasioptical gyro-TWT at MIT. The gyro-TWT is designed to operate in a higher order HE/sub 06/ mode of a confocal waveguide to produce 100 kW at 140 GHz with a gain of 38 dB. Current experimental results have demonstrated a peak power of 30 kW at 140 GHz with a gain of 29 dB and an unsaturated… (More)
