Maxim looks to raise the performance of GNSS Systems

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 can offer 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 has been designed to offer versatility and allows external filtering between first and second stage, providing flexibility for system optimisation. 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 MAX2670have both been designed on Maxim”s advanced, low-power SiGe BiCMOS process technology to offer the highest performance an integration at the lowest cost.  It is compatible with virtually all GNSS baseband hardware and GNSS software-based receiver designs.

The MAX2769B 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.
