Product Details

The MAX2771 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 Maxim’s advanced, low-power SiGe BiCMOS process technology, the MAX2771 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. The total cascaded noise figure of this receiver is as low as 1.4dB.

The MAX2771 completely eliminates the need for external IF filters by implementing on-chip monolithic filters and requires only a few external components to form a complete,low-cost GNSS RF receiver solution.

The MAX2771 is the most flexible receiver on the market. The integrated delta-sigma fractional-N frequency synthesizer allows programming of the IF frequency within a ±30Hz (fXTAL = 32MHz) accuracy while operating with any reference or crystal frequencies that are available in the host system. The ADC outputs CMOS logic levels with one or two quantized bits for both I and Q channels, or up to 3 quantized bits for the I channel. The on-chip ADCs can be bypassed and the analog I and Q signals output for sampling with external ADCs. An analog monitoring feature is provided that allows simultaneous output of the on-chip ADC samples and the I analog signal.

The MAX2771 is packaged in a 5mm x 5mm, 28-pin, TQFN package with an exposed paddle.
