Maxim Receiver & Amp Support Multiple Navigation Standards

November 1, 2013  by  


Maxim Integrated Inc. introduced the MAX2769B and MAX2670, specifically designed to address Global Navigation Satellite System (GNSS) applications.

These receiver solutions are capable of operating over the navigation standards GPS, GLONASS, Galileo, and Compass and have completed PPAP and AEC-Q100 approval.

The MAX2670 is a dual stage low noise amplifier typically located in or close to the antenna module, while the MAX2769B resides within the dashboard as the receiver.

The MAX2769B is said to offer the industry’s lowest noise figure of 1.4dB, a critical element that dominates the overall receiver sensitivity and enables faster satellite locking.

The MAX2670 allows external filtering between first and second stage, providing flexibility for system optimization. Its integration eliminates large, expensive, discrete transistor solutions. Combining these two parts delivers a highly flexible, high performance and robust system solution for navigation applications.

The MAX2769B and MAX2670 are designed on Maxim’s low-power SiGe BiCMOS process technology to offer the highest performance and integration at the lowest cost. It is compatible with virtually all GNSS baseband hardware and GNSS software-based receiver designs.

The MAX2769B completely eliminates the need for external IF filters by implementing on-chip monolithic filters and requires very few external components to implement a low-cost GNSS RF receiver solution. In addition, its integrated ADC, which is programmable from 1 to 3 bits, makes it highly configurable and the most flexible receiver on the market.

Pricing starts at $3.81 for MAX2769B and $2.22 for MAX2670 (1,000-up, FOB USA).
