PowerSmith©™ software celebrates 25+ years of functionality since concept! ← Smith Charts-Basics, Parameters, Equations, and Plots.Electronic Smith Chart program PowerSmith© by VA3DIW.Visit ABOUT to see what you can learn from this blog.’ ‘Note: This is an article written by an RF engineer who has worked in this field for over 40 years. If \(z=1.4+j1.2\), then, read directly from the Smith chart without using equations, what are the approximate values of: Let’s charge ahead to answer these simple questions below. You should go back to review this article- Basics, Parameters, Equations, and Plots, then come back to practice on this article again.Īfter that, you will be well prepared for learning impedance matching. However, do not force yourself ahead to the next article if you have difficulty to answer the following questions. You’ll learn a unique way of impedance matching using Smith chart, and you will also be directed to where you can get a powerful spreadsheet which will help you get the matching job solved within a fraction of a second with very minimal effort. If you can follow those 6 examples easily, then you are good to go to answer the questions below, and, once you get them done correctly, you can continue to learn the most exciting application of Smith chart, impedance matching. You don’t need to remember those equations by heart but you should know how to apply them without any difficulty, whenever you need to use it to conveniently solve impedance and reflection issues. With any one of these 3 parameters given, you can read the other 2 in the chart simultaneously with a very reasonable accuracy. Now, you have learned all basics of Smith chart and you know the chart is consisted of 3 very basic parameters, \(Γ, z, y\), and they can be converted among each other based on a few sophisticated equations. We’ll work on examples and then ask questions. This article will be dedicated to examples and questions to find out how much you really know about Smith chart and enhance your understanding of this great chart.īut you should learn all Basic Parameters, Equations, and Plots first before continuing reading further here.
