This technology revolves around ParkerVision's revolutionary approach to RF receivers using energy-sampling techniques. Historically, super-heterodyne technology was the cornerstone for handset receivers, characterized by multiple down-conversion steps employing traditional mixers. These demanded high local oscillator power, a hindrance in low-power-CMOS applications. ParkerVision innovated by developing RF energy sampling techniques, producing practical matched-filter correlators for frequency down-conversion. This innovation achieves unmatched sensitivity, bandwidth, and dynamic range for direct-conversion receivers, while enhancing selectivity and interference rejection.
By eliminating RF signal splitting between I and Q paths, ParkerVision's technology reduces power consumption and improves demodulation precision. The technology's compact and cost-effective nature supports low silicon area usage, thanks to fewer resonant structures and the elimination of many external filters. Widely applicable, the technology is adept at integrating into devices like handsets, modems, and tablets across various standards (GSM, EDGE, CDMA, UMTS, LTE), enabling increased device functionality with reduced footprint and cost.
