About RF Cafe

    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...

RF Shields Designed specifically for your prototype shielding requirements, we offer a wide variety of RF shield sizes that are available for immediate shipping and no phototooling charges. The standard shields that we offer are the perfect solution for preliminarily determining the effect of shielding over your board-level components. Click Here.
