Investigation of chaotic mode of active determinate oscillating system which is excited by negative resistance of non-linear element

The present paper addresses to investigation of switching between chaotic and stable oscillations of active determinate oscillating system which is microwave oscillator. Conditions of oscillations' switching to chaos are discussed. The system of oscillations is excited by negative resistance of non-linear element which is avalanche transit time oscillator diode. The obtained results could be used for designing of noise generators of active antenna arrays.
