Multiband receiver for Global Navigation Satellite Systems (GNSS) signals

摘要

RF receiver (40) for GNSS signals, (GPS, Galileo, Glonass), composed of a single chip (45) and a low number of external components, has a number of independent signal paths(180a-180-c) each including a separate IF stage and baseband down-converter (160). 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 (RF-LO).
