Maxim Advances the Performance of GNSS Systems with Introduction of its Automotive Grade Universal Receiver and Front End Amplifier

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 boasts the industry's lowest noise figure of only 1.4dB, a critical element that dominates the overall receiver sensitivity and enables faster satellite locking. The MAX2670 is a highly versatile design that allows external filtering between first and second stage, providing flexibility for system optimization. Its high 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 advanced, 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.

“These innovative navigation and active antenna RF products complement our existing radio, TV, LNA and VCO offerings for the automotive infotainment market,” said William Chu, Business Director at Maxim Integrated Products. “Maxim is devoted to advancing performance standards and offering high value solutions to the automotive and industrial markets – the MAX2769B and MAX2670 are just a few examples of this.”

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).
