Various variants of high-orbit Gyro-TWT in terms of efficiency, gain bandwidth and power are described and compared, as a result of their simulation using the Gyro-K program. The capabilities of such devices in terms of gain, gain band, efficiency and frequency range have been determined. It is shown that the best option is the operation of the Gyro-TWT at the second harmonic of the gyrofrequency and the TE21 wave mode, which is provided by a good coupling coefficient of this wave with the high-orbit electron beam and allows, at a gain of 40 dB, to have a gain band of ~ 12% and an average wave efficiency of 15%.
