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...

Three two-hour sessions. Timing-related problems associated with signal sources are one of the major bottlenecks in designing today’s highly complex systems. Over many decades, jitter has been extensively studied and utilized to characterize timing inaccuracies in both digital and analog systems. Conversely, phase noise has been exclusively used in RF systems to represent frequency or phase inaccuracy. For both timing and frequency sensitive systems, phase noise measurement is emerging to be the most accurate method of characterizing all types of signal sources (RF, analog or digital)....

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.
