The first major new release of RF Cafe's spreadsheet (Excel) based engineering and science calculator is now available - Espresso Engineering Workbook™ (click to download).  RF Cafe Espresso Engineering Workbook™ is provided at no cost, compliments of my generous sponsors.

The original calculators are included, but with a vastly expanded and improved user interface. Error-trapped user input cells help prevent entry of invalid values. An extensive use of Visual Basic for Applications (VBA*) functions now do most of the heavy lifting with calculations, and facilitates a wide user-selectable choice of units for voltage, frequency, speed, temperature, power, wavelength, weight, etc. In fact, a full page of units conversion calculators is included. A particularly handy feature is the ability to specify the the number of significant digits to display. Drop-down menus are provided for convenience.

Now that a more expandable basis has been created, I plan to add new calculators on a regular basis.

For the time being, the worksheets and VBA code are password protected. At some point, a version might be made available with full access, but during the development stage, I prefer to not expose all my hard work for easy poaching.

A lot of effort has been expended validating calculations, including references from books, magazines, and other software. As always, you are advised to check results against other sources if something seems off. If you do find an error, please report it to me ASAP so it can be corrected with the next release.

The file is in an xlsx format compatible back to Excel 2007 - and it may work for even earlier versions.

In appreciation for RF Cafe's sponsors, hyperlinked thumbnails to their websites are included on the homepage.

* Note: Because VBA code is used, you must allow Excel security to enable macros.

This edition includes the following 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...
