Nonlinear compensation in electronic systems at two-tone high-frequency excitation

An universal method of suppression of the intermodulation products in output signals of nonlinear electronic systems is considered at two-tone high-frequency excitation of an external electromagnetic field. The distorting system is represented as ≪a black or grey box≫ and linearization of its characteristic is carried out with the help of isolation of the linear functional from Volterra polynomial describing an input-output relation of the initial electronic system. Compensation of nonlinear transformation of a detector is performed with use of the measured sets of input and output signals. Quality of executed compensation is estimated.
