Mouser now stocks the MAX2769C universal GNSS receiver from Maxim Integrated. Claimed to be one of the industry's first universal, single-chip GNSS receivers for GPS (L1 C/A code and P-code), Galileo, BeiDou and GLONASS navigation satellite systems, the device requires only a few external components to form a complete low-cost GPS receiver solution. Engineered using the company’s low-power SiGe BiCMOS process technology, this Universal GNSS Receiver is a complete receiver chain on a single chip that provides both high performance and remarkable integration at a low cost for a variety of industrial- and consumer-based RF applications.

The receiver differs from competing solutions with a highly integrated design that eliminates the need for external LNA and IF SAW filters, allowing the device to achieve a total cascaded noise figure of 1.4dB. Using their SiGe BiCMOS process technology, the chip integrates a complete receiver chain that includes a dual-input LNA and mixer, image-rejection filter, VGA, VCO, fractional-N frequency synthesizer, crystal oscillator and a multi-bit ADC. The delta-sigma fractional-N frequency synthesizer enables IF programming with ±40Hz accuracy while operating with any reference or crystal frequency available in the host system. The integrated ADC outputs provide one or two quantized bits for both I and Q channels or three quantized bits for the I channel. Output data is available either at CMOS or at limited-differential logic levels.

Supporting development of the device is the company’s MAX2769CEVKIT evaluation kit, which enables complete performance testing of the MAX2769C and requires no additional support circuitry. The fully assembled and tested kit includes standard 50ohm SMA connectors for quick and easy evaluation on the test bench. Designed to work with most GPS baseband processors on the market, the device is ideal for a wide range of RF applications, including automotive navigation, asset tracking, cellular handsets, portable navigation devices, digital cameras, and ultra-mobile personal computers.
