A series of tutorials in "chalk-talk" format, similar to courses on the popular "Khan Academy" site.1. Signal Flow Graphs with Rex Frobenius:Signal Flow Graphs allow RF/Microwave circuit designers to use graphical techniques as an alternative to brute-algebraic approaches. By learning four key tools for working with the graphs, the majority of circuit problems can be analyzed.

The need for impedance matching is rooted in basic AC circuit analysis principles. In basic terms, maximum power transfer occurs when the current and voltage are in phase. This workshop examines analytical techniques to design impedance matching networks that deliver the most power possible to an RF load. Q factor and its effect on matching network bandwidth are also described.Online WorkbookThe course includes an online workbook exercise to design a single section and broadband matching network using the techniques described in the lecture. The resulting matching network is also demonstrated...
