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.
