Electronics Themed Crossword Puzzle
December 4th, 2022

Here is your custom made Electronics Themed crossword puzzle for December 4th, 2022. The four newly minted numerical prefixes are included and are indicated with an asterisk (*). The prefixes were declared in 2022 by the General Conference on Weights and Measures in Versailles, France. All RF Cafe crossword puzzles are custom made by me, Kirt Blattenberger, and have only words and clues related to electronics, electricity, radio, radar, RF, microwave, and mm-wave engineering, optics, mathematics, chemistry, physics, and other technical subjects. As always, this crossword contains no names of politicians, mountain ranges, exotic foods or plants, movie stars, or anything of the sort unless it/he/she is related to this puzzle's technology theme (e.g., Reginald Denny or the Tunguska event in Siberia). The technically inclined cruciverbalists amongst us will appreciate the effort. Enjoy!

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

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...
