Abstract
A high average power gyro-TWT operating in the low-loss TE/sub 01/ mode is being constructed that will be driven by a 100 kV, 5 A, v/sub /spl perp///v/sub z/=1.0 MIG electron beam with /spl Delta/v/sub z//v/sub z/=5%. The single-stage amplifier is predicted by a large-signal simulation code to generate 145 kW at 94 GHz with 29% efficiency, 54 dB saturated gain and 5% bandwidth.
