MAX2771ETI+

MAX2771ETI+ is a multiband universal GNSS receiver. This is a next-generation global navigation satellite system (GNSS) receiver covering E5/L5, L2, E6, E1/L1 bands and GPS, GLONASS, galileo, QZSS, IRNSS, and beidou navigation satellite systems on a single chip. Designed on Analog Device's advanced, low-power SiGe BiCMOS process technology, this device offers the highest performance and integration at a low cost. Incorporated on the chip is the complete receiver chain, including a dual-input LNA and mixer, followed by filter, PGA, and multi-bit ADC, along with a fractional-N frequency synthesizer, and crystal oscillator. It is used in applications such as location-enabled mobile handsets, PNDs (personal navigation devices), telematics (asset tracking, inventory management), marine/avionics navigation, software GPS, laptops and netbooks, surveying equipment, digital still cameras and camcorders, vehicle tracking and fleet management.
