Featured Product Archive The inventions and products featured on these pages were chosen either for their uniqueness in the RF engineering realm, or are simply awesome (or ridiculous) enough to warrant an appearance. | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 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.
