There were developed algorithms of parametric synthesis of block diagrams of amplitude-phase modulators specified by cascade connection of signal source, integrated four-pole device, unit containing multi-polar non-linear element and feedback circuit, and loading. There was defined set of relationships between elements of classical matrix for transfer of integrated, connected before loading four-pole networks to be optimal by the criterion to provide the specified relations and phase differences of modulator transfer functions in two states of non-linear element corresponding to two levels of low-frequency control signal amplitude taking into account parallel and serial by voltage and current feedback circuits. It was demonstrated that the resultant relationships physically mean requirements to provide the specified values of input conductance for integrated four-pole devices. To provide carrying out of these requirements, there were obtained impedance-versus-frequency dependences of integrated two-terminals within standard for-pole networks and mathematical models of quasi-optimal two-terminals to provide implementation of optimal frequency characteristics in a limited bandwidth. The comparative analysis of the theoretical results received on the basis of use of the developed mathematical modulator models in the MathCad system and the experimental results received by general-circuit simulation in the OrCad and MicroCap systems showed their satisfactory coincidence.
