Additional 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 (f_XTAL = 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.

Product Detail

The MAX2771 evaluation kit (EV kit) simplifies evaluation of the MAX2771, a next-generation Global Navigation Satellite System (GNSS) receiver covering the L1, L2, L5, E1, E5, E6, B1, B2, and B3 bands, as well as the GPS, GLONASS, Galileo, QZSS, IRNSS, and BeiDou navigation satellite systems on a single chip. It enables testing of device performance and requires no additional support circuitry. Standard 50Ω SMA connectors are included on the EV kit for the inputs and outputs to allow for quick and easy evaluation on the test bench.

The MAX2771 EV kit contains a microcontroller (MCU) that translates between the three-wire SPI interface and USB to allow the user to configure internal registers and modes with Graphical User Interface (GUI) software running on a PC. The EV kit is fully assembled and tested at the factory.

This document provides a component list, a list of equipment required to evaluate the device, a straightforward test procedure to verify functionality, a description of the EV kit circuit, the circuit schematic, and artwork for each layer of the printed circuit board (PCB).
