Radio frequency networks are characterized using S (scattering) parameters, and this video provides an easy introduction to S parameters and how they are used to quantify impedance matching and power transfer in radio frequency networks.
The Smith chart is one of the most important tools in understanding RF impedance and matching networks. This brief tutorial explains what the Smith chart is and how it can be used to represent complex impedances.
This video provides a basic introduction to voltage standing wave ratio (VSWR) and return loss, and explains how these measurements are used in radio frequency applications.
