A highly-integrated 3G CDMA2000 1X cellular baseband chip with GSM/AMPS/GPS/Bluetooth/multimedia capabilities and ZIF RIF support

This paper presents a 3G CDMA2000 1X cellular-baseband chip, with GSM/AMPS/GPS/Bluetooth/multimedia capabilities, which uses an embedded ARM and two DSP processors. It is implemented with 27 M transistors in 46.9 mm/sup 2/ using a 130 nm dual-V/sub T/ low-power CMOS process and achieves a three to four times standby-time improvement by the selective use of footswitches.
