BECAUSE THE BASEBAND FUNCTIONALITY is already available, all that is needed for a complete Global Positioning System (GPS) receiver is often an additional GPS radio-frequency integrated circuit (RF IC). The MAX2769E/W, for example, is a global-navigation-satellite-system (GNSS) receiver for GPS (L1 C/A code and P-code), WAAS, EGNOS, Galileo, and GLONASS navigation satellite systems. This RFIC provides a total cascaded noise figure of 1.4 dB and is designed for die-level integration into a single package. Incorporated on the MAX2769E/W is a complete receiver chain. The IC's delta-sigma, fractional-N frequency synthesizer allows intermediate frequency (IF) programming with +/-40-Hz accuracy while operating with any reference or crystal frequency available in the host system. P&A: $2.95 and up (1000 qty.).
