METHOD TO GENERATE HIGH-FREQUENCY SIGNALS AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC H03B5/00 

FIELD: electricity.

SUBSTANCE: in the method energy of a DC voltage source is converted into energy of a high-frequency signal, as the high-frequency signal interacts with a direct transmission chain, a three-pole non-linear element and an external feedback chain, and the excitation condition is met in the form of amplitude balance and phase balance that accordingly determine amplitude and frequency of generated high-frequency signals. At the same time the load is made in the form of the first dipole with complex resistance, connected to a control electrode of the three-pole non-linear element into a transverse circuit, excitations conditions are made in the form of amplitude balance and phase balance, and matching conditions are simultaneously realised at the specified quantity of frequencies due to selection of values of imaginary components of resistances of the first X_nm and second X_0m dipoles, provided that the stationary generation mode is provided in the form of transmission coefficient denominator equality to zero in the amplification mode simultaneously at all specified frequencies of generated high-frequency signals with invariable amplitude of the DC voltage source in accordance with mathematical expressions.

EFFECT: simultaneous provision of generation of a high-frequency signal at two specified frequencies due to selection of a scheme and values of reactive element parameters by criterion of compliance with conditions of phase and amplitude balance at these frequencies with invariable condition of a non-linear three-pole element.
