    Kirt Blattenberger,


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...

Microwave Engineering Crossword Puzzle
February 7, 2016

For the sake of avid cruciverbalists amongst us, each week I create a new crossword puzzle that has a theme related to RF, microwave, electrical and mechanical engineering, mathematics, chemistry, physics, astronomy, mathematics, and other technical words. You will never be asked the name of a movie star unless he/she was involved in a technical endeavor (e.g., Hedy Lamarr). Enjoy!

acr. = acronym, abbr. = abbreviation, pl. = plural, wds. = words
