Abstract
The analysis of even simple microwave circuits can involve complicated calculations. It is argued that students repeatedly forced through this exercise are left exhausted and never develop understanding and insight into the principles of high-frequency circuit design. The use of computer-aided design software eliminates the network analysis burden, but it is a precarious solution: students easily become dependent on software and never develop analytical skills. A simple wave computational approach to microwave network analysis is discussed. The method is derived from Mason's theory of signal flow graphs and is based on wave variables and scattering parameters. The approach is easily understood and applied as either an analytical tool, or within a microwave CAD analysis engine. PC software using this computational technique is described and its educational applications are discussed. >
