If a circuit consists of linear elements, then it can be represented by a set of linear equations relating its independent quantities, like currents and voltages, to its dependent quantities, also currents and voltages. We all want to understand and predict how a circuit works, so we want to be able to represent circuit behavior by using mathematical expressions or equations. Thankfully, these are all simple concepts and we'll help you master them right here at Microwaves101! History of S-parameters When you come down to it, there are really only a few things that separate a microwave engineer from a 'normal' electrical engineer: knowledge of the Smith chart, S-parameters, transmission lines including waveguides, and decibels. Here's a page on mixed-mode S-parameters. Here's a page on cold S-parameter measurements. Here's a page covering the most common network parametersВ and their interrelationships including s-parameters. Here's a page on transfer S-parameters, which are more friendly if you want to cascade blocks.
