毫米波Gunn器件谐波振荡器电路分析

ANALYSIS OF MILLIMETER WAVE GUNN HARMONIC OSCILLATORS BY A CIRCUIT MODEL

根据ＧａＡｓＧｕｎｎ器件的谐波大信号特性，应用描述函数法对毫米波二次谐波振荡器的电路特性进行了研究，分析了振荡频率和输出功率随器件大信号特性参数与外电路参数变化的规律。

By applying the describing function method,the circuit performance of millimeter wave second harmonic oscillators was investigated based on a large signal model of GaAs Gunn diode at harmonic frequencies.The oscillation frequency and the output power were calculated as the functiions of the nonlinear characteristic and the external circuit parameters.The deduced conclusions are in coincidence with the experiments.
