An indispensible tool for solving transmission line and waveguide problems, the Smith chart was invented in 1939 by Phillip H. Smith as a graph-based method of simplifying the complex math (that is, ...

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 ...

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 ...

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 ...

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 ...

The Smith chart is a staple for analyzing complex impedance. [W2AEW] notes that a lot of inexpensive test gear like the MFJ-259B gives you complex readings, but fails to provide the sign of the ...
