Some tuning characteristics and oscillation conditions of a waveguide-mounted transferred-electron diode oscillator

Several tuning characteristics of waveguide-mounted transferred-electron diode oscillators, previously observed experimentally, are discussed, Frequency tuning, jumping, and saturation along with output power variation and jumping, are related to the mounting and device parameters. Two oscillation conditions relating to multifrequency resonant circuits and oscillator power output are cited to explain theoretically these observed characteristics, leading to accurate prediction of circuit behavior. This is accomplished through study of the terminal impedance of a new and improved equivalent circuit for a diode mount.
