[Ralph] is excited about impedance matching, and why not? It is important to match the source and load impedance to get the most power out of a circuit. He’s got a whole series of videos about it. The ...

Upon initial look, the Smith chart appears to be quite complicated. Although the basis for the chart is deeply rooted in complex variable theory, you do not have to be a graduate-level mathematician ...

The Smith chart appeared in 1939 (Ref. 1) as a graph-based method of simplifying the complex math (that is, calculations involving variables of the form x + jy) needed to describe the characteristics ...

You have probably heard the statement about standing wave ratio: “I changed the length of the transmission line and reduced the SWR.” Or the opposite statement, “I changed the length of the ...

I've covered several different programs that are useful when doing electrical engineering in the past. In this article, I want to look at a program called linsmith that helps you do calculations or ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. What you’ll learn: Plot complex impedances on a Smith chart. Determine SWR from the Smith chart. Determine the ...
