METHOD FOR GENERATING AND FREQUENCY MODULATING HIGH-FREQUENCY SIGNALS AND RESPECTIVE DEVICE Russian patent published in 2016 - IPC H01P1/00 H03J3/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention may be used to create devices generation and frequency modulation with increased frequency linear portion of the modulation characteristic at arbitrary characteristics of the nonlinear element circuit and external feedback resistive quadrupole parameters. In the method and device as a circuit external feedback using arbitrary two-port is connected to a three-pole non-linear element by a series-parallel circuit, a three-pole non-linear element and a feedback circuit as a unit, cascade inserted between administration of the second two-pole with a complex resistance simulating impedance signal source generator mode gain, and the input of the resistive two-port, provided in the form of balance of excitation amplitude and phase balance and consistency condition performed at a quasi-linear dependence of the amplitude of the oscillation frequency control signal by choosing the frequency dependence of the imaginary component of the resistance source in the amplification mode.

EFFECT: technical result is to increase the area of quasi-linear modulation characteristics when using non-linear circuit element and external feedback.
