Abstract

In this work, synthesis of microwave amplifier is put forward as a constrained vector optimization problem whose components are to meet the specific gain value constrained by the minimum noise over the available bandwidth. Nondominated solutions are acquired using the nondominated Sorting Genetic Algorithm-II as a fast nondominated genetic sorting algorithm wherefore these synthesis objectives generally conflict with each other. Then, the Pareto frontiers are obtained using these trade-off solution sets between the performance characterization of the device results in the triplet of gain GT, noise F, and input VSWR Vi and its source (ZS) and load (ZL). It can be concluded that the Pareto-optimal synthesis procedure provides microwave amplifier with optimum performance. (c) 2012 Wiley Periodicals, Inc.
