- Abstract
In this paper, the effects of harmonic load impedance of the terminating network on the input impedance and the output power of the equivalent one-port negative resistance MESFET oscillators are investigated. Harmonic balance techniques in conjunction with a nonlinear MESFET transistor model are used to simulate the nonlinear response of such one-port negative resistance oscillators. An appropriate Fourier development of steady State voltage and a current wave forms obtained for a given amplitude and frequency signal are used to calculate the input negative resistance and reactance in device line simulations. It was found that the output power of a one-port negative resistance MESFET oscillator can be maximized by optimizing the harmonic load impedances of the terminating network.
