ABSTRACT
Chaotic dynamics of electronic circuits and systems is attracting the interest of researchers for the last few decades, mainly because of its potential for application in electronic communication systems. Different methods can be proposed to drive a microwave Gunn oscillator into chaotic mode. Among them, an injection-locked Gunn oscillator driven by a weak co-channel signal may be a feasible technique. The present work considers this method through a hardware experiment and finds that under certain conditions of interference strength and detuning, chaotic oscillations of a Gunn oscillator can be observed.
