RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

New RF Applications for the 3-D Smith Chart

New Applications for the 3-D Smith Chart - RF Cafe3-D Smith Chart software inventor Andrei Muller has been working overtime to demonstrate the unique capabilities of his brainchild to the engineering world, with the latest effort being a presentation at the Asia-Pacific Microwave Conference in December 2012 (see also IEEE June 2011 MWCL and the July 2012 Microwave Journal articles). Having begun as part of his doctoral thesis, the original 3-D Smith Chart program capabilities are being extended to make direct application to real-world RF design tasks more convenient. Examples are provided on Andrei's website that include amplifier stability circles, and complex matching of lossy lines. The primary advantage of the 3-D Smith Chart is its ability to display both the entire reflection coefficient and impedance planes, something even an extended 2-D Smith Chart cannot do. Access to the 3-D Smith Chart is free now, but a donation will be appreciated. I suspect it will not be long before you see the high-end simulators incorporating this tool.
