ABSTRACT:
RF receiver for GNSS signals, (e.g., GPS, Galileo, Glonass), composed of a single chip and a low number of external components, has a number of independent signal paths each including a separate IF stage and baseband down-converter. Each signal path is tuned to a specific IF band by selection of external IF filters. Conversion to IF involves a common local carrier generator.
