Excel Spreadsheet Calculators

Microsoft stopped supporting the Office Web Components that are required for the spreadsheet-based online calculators, so I replaced them all with either JavaScript code or with the new SkyDrive-based Excel spreadsheets that work with all browsers.

Many of these calculators and a lot more are included in Espresso Engineering Workbook™ for FREE.

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 lady's voice announced "You've Got Mail" when a new message arrived...
