The dispersion characteristics and beam-wave interaction simulation results for a 140 GHz confocal gyro-travelling wave tube are presented with the help of CST Microwave Studio and 3D PIC software. The TE06 mode of a confocal waveguide is chosen as the operating mode. At a voltage of 35 kV, current of 2 A, and horizontal to vertical velocity ratio of 0.85, a 3 dB bandwidth of over 3.5 GHz is achieved in simulation, along with the peak output power of 2 kW and the peak saturated gain of over 30 dB, when the input power is about 1 W.
