Abstract :
A non-linear mixed analysis/optimization algorithm for the design of microwave power amplifiers is presented. Matching conditions for optimum power and efficiency performance are imposed together with the balancing equations of the non-linear analysis in a consistent way. The analysis/pre-optimization of the power stage requires a computation time comparable to that of a single conventional harmonic balance analysis. The algorithm forms the basis of a design procedure for the fulfilment of design specifications in terms of output power, power-added efficiency and gain. Comparisons with the results of commercial CAD non-linear analysis programs are presented
