Maxim Integrated Products unveiled a single-chip, RF front-end for global-positioning-systems (GPS).

According to the press release, the high-performance, state-of-the-art MAX2745 offers the highest integration in the industry as it eliminates the need for costly SAW and bulky discrete IF filters which results in a lower BoM cost and reduced board area.

The new device supports both 3rd overtone crystal designs in 32MHz and fundamental-frequency crystal designs in 16MHz, as well as TCXO implementation. In addition, it incorporates an on-chip temperature sensor and crystal oscillator with trimmed capacitors, providing a very accurate frequency and additional system cost savings.

Target applications include general navigation and tracking systems, such as in-vehicle navigation, fleet management, asset tracking and management, LBS (Location-Based Services), emergency/roadside assistance, GIS (Geographical Information Systems), recreational handheld and marine navigation systems, as well as many mobile and battery-operated consumer electronics.

The MAX2745 is available in a 48-pin TQFP package and is specified for the extended temperature range of -40C to 85C. Prices start at $4.78 (500-up, FOB USA). An evaluation kit and samples are already available.
