METHOD OF GENERATING HIGH-FREQUENCY SIGNALS AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2013 - IPC H03B5/00 

FIELD: radio engineering, communication.

SUBSTANCE: method of generating high-frequency signals is based on interaction of a high-frequency signal with a forward path, a three-terminal nonlinear element and an external feedback circuit, wherein the forward path is made from a three-terminal nonlinear element; the external feedback circuit used is an arbitrary four-terminal element connected to the three-terminal nonlinear element on a parallel-series circuit; the load is in form of a first two-terminal element with complex resistance; the control electrode of the three-terminal nonlinear element is connected through a cross circuit to the complex resistance, which imitates resistance of the signal source of the generator in gain mode; excitation conditions in form of amplitude balance and phase balance and matching conditions are simultaneously satisfied on the given number of frequencies by selecting values of imaginary components of resistance of the first X_nm and second X_0m two-terminal elements in accordance with mathematical expressions.

EFFECT: wider range of generated vibrations, generation of high-frequency signals on a given number of frequencies and fewer reactive elements.
