NONLINEAR MIXED ANALYSIS OPTIMIZATION ALGORITHM FOR MICROWAVE-POWER AMPLIFIER DESIGN

A nonlinear mixed analysis/optimization algorithm for the design of mi crowave power amplifiers is presented, Matching conditions for optimum power and efficiency performance are imposed together with the balanc ing equations of the nonlinear analysis in a consistent way, The analy sis/preoptimization of the power stage requires a computation time com parable to or smaller than a single conventional harmonic balance anal ysis, The algorithm forms the basis of a design procedure for the fulf ilment of design specifications in terms of output power, power-added efficiency, and gain, Comparisons to the results of commercial CAD non linear analysis programs are presented.
