Abstract
The dc current-voltage characteristics of microwave diodes are experimentally studied on simultaneous exposure of the diodes to a high-frequency (100 MHz) high-amplitude harmonic signal. In the current-voltage characteristics of the microwave diodes, regions of N-type negative differential resistance, hysteresis, and current oscillations are observed depending on the amplitude and frequency of the high-frequency signal. A comparative analysis of the experimentally observed effects is performed, and possible mechanisms for the effects are discussed.
