Abstract :
Nonlinear analysis of a high-power gyro-TWT amplifier operating in TE01 mode has been investigated through particle-in-cell (PIC) simulation using CST-studio. The simulation results are validated against published results with close accuracy. The simulation predicts 150 kW output power at 34 GHz with 21% efficiency, 48 dB saturated gain and 1.3 GHz bandwidth.
