Parametrical synthesis of radio devices with the set quantity of unequal cascades for variants of inclusion of jet two-port networks between a nonlinear part and loading
The algorithm of parametrical synthesis of various radio devices with any quantity of cascades of type «a nonlinear part – the jet two-port network» by criterion of maintenance of the set frequency characteristics is developed. Nonlinear parts are presented in the form of a nonlinear element and par...

| description | The algorithm of parametrical synthesis of various radio devices with any quantity of cascades of type «a nonlinear part – the jet two-port network» by criterion of maintenance of the set frequency characteristics is developed. Nonlinear parts are presented in the form of a nonlinear element and parallel either consecutive on a current or pressure of a feedback. According to this criterion systems of the algebraic equations are generated and solved. Models of optimum two-port networks of one of cascades in the form of mathematical expressions for definition of interrelations between elements of their classical matrix of transfer and for search of dependences of resistance of two-poles from frequency are as a result received. It is spent mathematical and circuit simulation of the two-cascade amplifier. It is shown, that the increase in quantity of cascades with the optimised parametres leads to substantial growth of a working strip of frequencies. The comparative analysis of the theoretical results received by mathematical modelling in system «MathCad», and the experimental results received by circuit simulation in systems «OrCad» and «MicroCap», shows their satisfactory coincidence. |
