Description The ATR0635 is a low-power, single-chip GPS receiver, especially designed to meet the requirements of mobile applications. It is based on Atmel’s ANTARIS™4 technology and integrates an RF front-end, filtering, and a baseband processor in a single, tiny 7 mm × 10 mm 96 pin BGA package. Providing excellent RF performance with low noise figure and low power consumption. Due to the fully integrated design, just an RF SAW filter, a GPS...
