METHOD OF MATCHING COMPLEX IMPEDANCES AND APPARATUS FOR REALISING SAID METHOD Russian patent published in 2013 - IPC H03J3/00 H03H7/38 

FIELD: radio engineering, communication.

SUBSTANCE: matching device is connected between a high-frequency signal source and a load, the matching device being made from a four-terminal element, parameters of which are selected based on the condition of ensuring a minimal reflected signal. The four-terminal element is complex and consists of reactive and resistive elements; the output of the high-frequency signal source is connected to the input of the complex four-terminal element; a two-terminal nonlinear element is connected in a longitudinal circuit between the output of the four-terminal element and the load; the nonlinear element is connected to a low-frequency control signal source, wherein the frequency dependency of the element z₁₁ of the array of resistances of the complex four-terminal element is selected using a mathematical expression.

EFFECT: wider field of physical implementation of regions of variation of real and imaginary components of resistances of the signal source and the load, within which full matching of complex resistances of the signal source and the load can be carried out successively for the given number of frequencies.
