    3. TECHNICAL DESCRIPTION 3.1.16 A-GPS GT500 supports A-GPS operation using Broadcom BCM4750 A-GPS module. The BCM4750 is a single chip, single die AGPS receiver that combines a high-performance RF front end with an adaptive baseband processor. The BCM4750’s small footprint and minimal parts count provide significant reductions in the design, layout, manufacturing, and testing resources required to integrate AGPS technology with mobile handsets and portable devices.
