Maxim Integrated Products has released the MAX2769E/W—the industry's first universal, global navigation satellite system (GNSS) receiver for GPS (L1 C/A code and P-code), WAAS, EGNOS, Galileo, and GLONASS navigation satellite systems in a single tested die. The MAX2769E/W RFIC provides a total cascaded noise figure of 1.4dB and is designed for die-level integration into a single package. Consequently, this receiver is ideal for a wide range of consumer applications, including automotive navigation, asset tracking, cellular handsets, portable navigation devices (PNDs), digital cameras, laptops, and ultra-mobile personal computers (UMPCs).
Designed on Maxim's advanced, low-power SiGe BiCMOS process technology, the MAX2769E/W offers the industry's highest performance and integration at a low cost, incorporating 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. Through this high level of integration, the MAX2769E/W eliminates the need for external IF SAW filters, as well as an external LNA in passive antenna applications. Consequently, it requires only a few external components to form a complete, low-cost GPS receiver solution.
