This FFT development board from RHDC Services features a fully functional audio band spectrum analyzer for just £59.95 ($95.35). An ultra low power Sharp 96x96-pixel display and judicious selection of processor and peripheral components yields a module that consumes only 3 μA in a static state and 1.3 mA while FFT'ing. Per their website, "The FFTD1A can typically display an image and maintain a real time clock using less than 10µW. Assuming a CR2032 coin-cell delivers 200mAh, that's around 6 years battery life." FFT Designer software together with the FFTD1A development board allows users to develop application software that performs Fourier analysis with a 12-bit, 200 ksps input and a 50 dB SFDR. Add a simple mixer, LO, and filter to extend the useful range to just about any frequency band. RHDC Services also provides RF R&D and communication systems engineering services.

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...
