RFMD GPS RF8110 Benefits

As a software-based solution, the RFMD GPS RF8110 offers scalable performance depending on the required sensitivity, accuracy and end-user application. The solution supports push-to-fix, Location Based Services (LBS) applications as well as automotive and pedestrian navigation in outdoor and low signal strength environments. The RFMD GPS RF8110 reduces the total bill-of-materials (BOM) and leads to significant cost and size savings. In large volumes, the price of the RFMD GPS RF8110 RFIC bundled with core GPS software is approximately $3.00.
The hardware component of the solution is a mixed-signal RFIC built in 0.18 um CMOS technology for low power and small size. The RFIC has a hardware accelerator on-chip to offload the system's applications processor and to minimize the data transfer rate to the host CPU. Low power consumption is achieved through various hardware and software-controlled power save modes.
