RF & Microwave Engineering Crossword Puzzle

For the sake of avid cruciverbalists amongst us, each week I create a new science themed crossword puzzle that has a theme related to engineering, mathematics, chemistry, physics, 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!

Reproduction of this puzzle without the express permission of RF Cafe is prohibited.

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

About RF Cafe

Copyright: 1996 - 2024


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