Operation features of a locked Gunn-diode microwave oscillator due to sign reversal of the nonlinear reactance of the diode

摘要

It is shown experimentally that the nonlinear reactance of a Gunn diode can reverse sign depending on the operation mode of the diode with respect to the direct current. We propose a method for determination of the factor describing the diode-reactance nonlinearity in the case of a locked Gunn-diode oscillator.
