"MEMS: RF-MEMS aims to tune mobile wireless"

As an aspiring fabless semiconductor house, WiSpry Inc. (Irvine, Calif.), recently laid claim to sampling the world's first integrated radio-frequency (RF) micro-electro-mechanical system. The MEMS chip--a digital capacitor array on a CMOS die--can match a cell phone's antenna impedance dynamically, rather having it set at the factory, saving dropped calls and extending battery life. And that's just the start, says WiSpry, for its forthcoming line of RF-MEMS devices, which the company says eventually will yield the holy grail of RF: software radio--an ultra-wideband communications channel that can be tuned to different bands anywhere in the spectrum.
