FIELD: radio engineering, communication.
SUBSTANCE: method for generation and frequency-modulation of a high-frequency signal is based on converting energy of a dc voltage source to energy of a high-frequency signal; interaction of the high-frequency signal with a forward transmission circuit, a three-terminal nonlinear element, a feedback circuit and a load; meeting excitation conditions in form of an amplitude balance and phase balance, which respectively determine the amplitude and frequency of the generated high-frequency signal, and conditions for matching the three-terminal nonlinear element with the load; varying frequency of the generated high-frequency signal according to the law of variation of the amplitude of the low-frequency control signal through corresponding variation of the phase balance. The forward transmission circuit is made from a three-terminal nonlinear element; the feedback circuit used is external feedback in form of an arbitrary four-terminal device connected in parallel to the three-terminal nonlinear element.
EFFECT: wider range of generated oscillations, generating complex signals, creating efficient compact generation devices for radio communication equipment with a given number of radio channels.
