HIGH-FREQUENCY SIGNAL GENERATION METHOD, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC H03B5/00 

FIELD: electricity.

SUBSTANCE: method is based on conversion of energy of constant voltage source to energy of high-frequency signal, organisation of internal feedback in non-linear element by using non-linear element with negative differential resistance as the above mentioned nonlinear element, fulfillment of excitation conditions in the form of amplitude balance and phase balance, which determine amplitude and frequency respectively of generated high-frequency signal, and matching conditions of two-pole nonlinear element with load by means of reactive four-pole circuit; at that, excitation conditions are fulfilled simultaneously at the specified number of frequencies due to interaction of high-frequency signal with radio-technical chain in the form of an additional two-pole circuit connected in series to two-pole nonlinear element with negative differential resistance, to which there connected is reactive four-pole circuit with load, and selection of frequency characteristics of reactive four-pole circuit provided that stationary generation mode is ensured.

EFFECT: wider range of generated oscillations.
