CMOS single-chip six-band transceiver fits UMTS world phones

Infineon Technologies is sampling what the company claims is the world's first CMOS single-chip RF transceiver specifically developed for UMTS applications. The SMARTi 3G supports all six frequency bands for UMTS now specified for operation in different parts of the world, includind Europe, Asia, North America, and Japan.

With respect to the downlink data capacity specified under HSDPA (High Speed Down-link Packet Access) between base station and mobile device, SMARTi 3G complies with category 8 of the HSDPA spec, featuring up to 7.2 Mbits/s. The data rate of today's UMTS phones without HSDPA accounts for 384 kilobit per second (kbit/s). In addition, the package size of SMARTi 3G is just 5 by 5 mm, which is 30% less than competitive packages.

Offering the same interfaces as its single band predecessor, SMARTi 3G is compatible with most existing base band solutions. It's manufactured using Infineon's standard 130-nm CMOS process technology and is housed in an 81-pin PG-WFSGA green package with a 0.5-mm pitch. Its supply voltage ranges from 2.7 to 3.0 V. The transceiver is available in sample quantities and volume shipments are expected to start at the beginning of 2006. Further information is available at
