The algorithms of parametric synthesis of amplifiers and phase-amplitude modulators by providing specified dependencies required for the modules and the phase difference of the transfer functions in the two states on the frequency .. The result obtained by the mathematical model the matching four-reactive as the optimum relationship between the elements of the transfer matrix for the case of using any number of linear and non-linear elements included on both sides of the quadripole. These relationships are used to form a system of algebraic equations whose solutions yielded mathematical expressions to determine the optimal reactive two-terminal resistance dependency of frequency for the two-port model schemes. The implementation of these features by means of quasi-two-terminal devices in the form of multiple-loop systems, depending on the frequency of resistance which coincide with the optimum in a limited frequency band. It is proved that the maximum achievable performance modulators are defined by so-called non-linear qualities of the elements, which are measures of differences of complex parameters for a specific part of the circuit containing a nonlinear element and a feedback loop in the two states.
