High Frequency Electronics Features Articles on Impedance Matching

The March 2008 issue of High Frequency Electronics featured two articles on impedance matching:

Improving the Bandwidth of Simple Matching Networks. This article discusses not only the classic L, T, and pi networks designed for a specific frequency, but also other circuit types that allow you to design a broad bandwidth matching network.
Matching Using Only 50-Ohm and 75-Ohm Transmission Lines. This short article shows you how to use a Smith Chart to match impedances using coaxial transmission lines. It includes a list of references to websites with info on the theory and use of the Smith Chart.

Again, thanks for links to neat articles. I have some quotes from my students that used your Study Guides. Sorry for not typing them up and sending them to you sooner. They are now by my keyboard, so maybe I can do that tonight.

Keep up the good blogging.

By the way, my students are just now beginning to use breadboards to build simple circuits (e.g. astable multivibrator to see transistor operation, etc…). Once they learn breadboard use, what simple circuits would you suggest? I’ve downloaded some simple FM transmitters, etc.. I think the kids will be interested in that. I’ll let you know.

What I might suggest is to have them build some kind of regenerative receiver. That way, when they’re finished, they have something they can listen to shortwave broadcasts and amateur radio operations.
