Worst-case models of RF front-end nonlinearity for discrete nonlinear analysis of electromagnetic compatibility

A worst-case approach to development of nonlinear models for RF front-ends and components is proposed. This approach makes it possible to avoid the omission of nonlinear interference in process of the computer simulation, which is very important for EMC analysis. Based on the proposed approach, we developed a technique for synthesis of the models intended for the use in framework of the discrete nonlinear analysis technology. For validation of the developed technique, nonlinear behavioral model of a microwave amplifier was synthesized.
