Designed for best indoor performance, the MAX2769E/W global navigation satellite system (GNSS) receiver for GPS (L1 C/A code and P-code), WAAS, EGNOS, Galileo, and GLONASS navigation satellite systems provides a total cascaded noise figure of 1.4 dB. Incorporated on the chip is a complete receiver chain, including a dual-input LNA and mixer, followed by an image-rejected filter, VGA, VCO, fractional-N frequency synthesizer, crystal oscillator, and a multibit ADC.

The GNSS receiver eliminates the need for external IF SAW filters, as well as an external LNA in passive antenna applications. The integrated delta-sigma fractional-N frequency synthesizer allows IF programming with ¡À40-Hz accuracy while operating with any reference or crystal frequency available in the host system.
