RF Engineering Online Calculators

I originally had a decent collection of online calculators that used the Office Web Components required for the spreadsheet-based online calculators, but Microsoft stopped supporting it many moons ago. I replaced some of them with JavaScript code calculators. If I don't get around to doing more in JavaScript, you can download my Espresso Engineering Workbook™ for FREE -- it has a LOT of calculators.

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 tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
