Abstract
The design and simulation results for a 140 GHz gyro-amplifier are presented. A bandwidth of over 3 GHz has been achieved in simulation with peak saturated gain of over 33 dB. Study dispersion characteristic and beam-wave interaction of the confocal waveguide. The HE06 mode of a confocal waveguide is chosen as the operating mode and distributed loss is employed via diffraction to stabilize the circuit.
