Gyro-amplifiers using helically corrugated waveguides have shown exceptional gain, power, bandwidth, and efficiency performance at cm and mm wavelengths. The performance of a long pulse (and therefore high vacuum) system is strongly
influenced by factors other than the intrinsic bandwidth of the interaction. We shall discuss these and other challenges, along with their mitigation in high average power wideband amplifiers.
