Today’s electronic-design-automation (EDA) software gives RF engineers extremely powerful tools that can take on design tasks for all microwave circuits, beginning with the electrical schematic designs and their substrate schematic layouts, and then moving on to circuit measurements. However, designing microwave power amplifiers is a complex process that involves a specific order of tasks to achieve the final product.
This article focuses specifically on using EDA software to execute one of several available methods to simulate and analyze amplifier stability. Along the way, we’ll look at some of the steps involved so that the final product is consistent with the design goals and requirements.
