FIELD: radio engineering.
SUBSTANCE: used in communication systems for transmission of information messages based on chaotic microwave pulses. To achieve the effect, the self-oscillator of chaotic pulses additionally contains a nonlinear amplifier, the input of which is connected to the output of the linear amplifier, and the output to a directional coupler, while the nonlinear delay line additionally contains a metal conductor placed on the surface of the periodic structure and connected to a direct current source. The nonlinear amplifier is designed to operate in the maximum output power mode, and the linear amplifier is a multi-cavity system, the resonant frequency of which is tuned to the central frequency of the stopband of the periodic structure.
EFFECT: ensuring a change in the level of nonlinear losses of a magnetostatic wave propagating in a dispersive delay line with a magnon crystal using a direct electric current.
