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

Mystery Molecule - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam. Note: The RF Cafe Forums were reconstituted in April 2021!

Below are the old forum threads, including responses to the original posts.

This molecule is for a liquid found useful by many visitors to RF Cafe.

OK, I'll take a crack at it. Is it Ethyl Alcohol?

Jason wins the prize!

Well, there isn't really a prize other than the satisfaction of knowing that you were the first to figure it out. Jolly good.

I ran across it while looking for some other chemical information. It was the Molecule of the Week on Chemstry.org.


"Beer flavor is a complex balance of sweetness from sugars and bitter from the humulones in hops (Humulus lupulus) flowers. When wort (unfermented beer) is boiled, humulone molecules rearrange to form the more soluble isohumulones (one example shown here). Isohumulones retard bacterial growth and contribute to beer's bitter flavor."
