Abstract :
A combined full-wave/circuit simulator model for a coaxial cavity Gunn oscillator is developed. The Gunn oscillator utilizes the second harmonic for the output power generation at 76 GHz. The model is validated with reflection coefficient and output power measurements. This combined model provides accurate and fast Gunn oscillator cavity design.
