Infineon Introduces First One-Chip Multi-Band WCDMA/EDGE Transceiver

Infineon Technologies announced sample availability of the SMARTi 3GE dual-mode WCDMA/EDGE radio frequency (RF) transceiver. With this newest addition to its SMARTi RF transceiver family, Infineon offers the world's first one-chip, six-band WCDMA (Wideband Code Division Multiple Access) and quad-band EDGE (Enhanced Data GSM Evolution) solution.

The SMARTi 3GE is based on the proven architecture of the SMARTi PM, a quad-band GSM/EDGE transceiver, and the SMARTi 3G, a six-band WCDMA transceiver with HSDPA (High-Speed Downlink Packet Access) capabilities. It measures just 6 by 6 square millimeters (0.24 x 0.24 square inches) and frees up more than 40 percent of board space compared to Infineon's previous two-chip solution, consisting of the currently available SMARTi PM and SMARTi 3G transceivers.

Full software compatibility of the SMARTi 3GE with the two-chip solution offers a smooth transition to the next integration step for all the customers currently working with stand-alone transceivers. Moreover, the standard I/Q interface and three-wire bus programming address the majority of available baseband processors.

SMARTi3 GE handles quad-band GSM/EDGE (850/900/1800/1900 MHz) and currently defined WCDMA bands I through VI, allowing global roaming between Europe, the USA and Japan. The integration of bands II (1900 MHz), IV (1.7/2.1 GHz) and V (850 MHz) is addressing the requirements of the USA market in particular. For emerging data applications, the SMARTi 3GE chip offers data rates as high as 7.2 Mbps in WCDMA downlink by supporting the HSDPA protocol category 8.

The SMARTi 3GE chip is based on Infineon's standard 130 nm CMOS RF technology. It is housed in Green (lead-free and halogen-free) leadless packages.

Samples are available now and are already evaluated by several customers. The ramp-up of SMARTi 3GE is scheduled for 4th quarter 2006.
