Universal GNSS RF receiver is fully programmable

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX2769E/W, a universal, global navigation satellite system (GNSS) receiver for GPS (L1 C/A code and P-code), WAAS, EGNOS, Galileo, and GLONASS navigation satellite systems.

The MAX2769E/W RFIC provides a total cascaded noise figure of 1.4-dB and is designed for die-level integration into a single package. Consequently, the MAX2769E/W is suitable 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).

The MAX2769E/W is designed using advanced, low-power SiGe BiCMOS process technology. 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 multi-bit 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.

Fully specified for operation over the -40°C to +85°C extended temperature range, the MAX2769E/W is available in a single tested-die, wafer-level (by request only), and 28-pin TQFN packages.

Pricing: Starts at $2.95 (1000-up, FOB USA).
Availability: Now.
