The MAX2769B is a next-generation Global Navigation Satellite System (GNSS) receiver covering GPS, GLONASS, Galileo, and Compass navigation satellite systems on a single chip. This single-conversion GNSS receiver is designed to provide high performance for industrial and automotive applications. Designed on Maxim’s advanced, low-power SiGe BiCMOS process technology, the MAX2769B 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 the image-rejected filter, PGA, VCO, fractional-N frequency synthesizer, crystal oscillator, and a multibit ADC. The total cascaded noise figure of this receiver is as low as 1.4dB. The MAX2769B completely eliminates the need for exter- nal IF filters by implementing on-chip monolithic filters and requires only a few external components to form a com plete low-cost GPS RF receiver solution. The MAX2769B is the most flexible receiver on the mar- ket.
The MAX2769B universal GPS receiver integrates a complete GNSS front‑end on a single SiGe BiCMOS chip, supporting GPS, GLONASS, Galileo and Compass. It offers a cascaded noise figure as low as 1.4 dB and includes on‑chip filters, a fractional‑N synthesizer, and a multibit ADC.
The device is supplied in a 28‑pin thin QFN package (5 mm × 5 mm), operates from 2.7 V to 3.3 V, and is qualified to AEC‑Q100 automotive standards. It targets automotive navigation, mobile handsets, PNDs, telematics, marine/avionics, and other location‑enabled applications.
