Philips Launches CDMA Chipset That Supports GPS
Philips Electronics has launched a tri-mode CDMA/AMPS integrated circuit that offers measured low-noise amplifier (LNA) figures in the cellular band of only 1.1 decibel (dB). The SA9505 semiconductor can support GPS functions, and can be used for other wireless systems, such as TDMA, EDGE and w-CDMA mobile phones. The SA9505 cellular-band LNA measures an average of 1.1 dB noise figure with 8.7 dBm IIIP3, 15 dB of gain, and 7.7 mA. The SA9505 IC has an integrated TX LO buffer and the capability for three independent IF outputs.
The tri-mode SA9505 IC can support E-911 and location-based services with the addition of a few discrete components.
"With the SA9505 IC, Philips is addressing an increasing demand among handset manufacturers for CDMA capability complete with GPS functionality for the savvy mobile consumer," said Joseph Bousaba, Cellular RF Sector marketing manager, the semiconductor division of Philips. "Moreover, by fabricating the SA9505 integrated receiver front-end using a silicon-only process, Philips is able to maintain its position as a leading supplier of RF chips to the mobile telecommunications industry."
