Infineon Technologies, a provider of communication ICs, today presented two new single-chip RF CMOS transceivers. SMARTi PM+ and SMARTi UE set new benchmarks in terms of miniaturisation, integration and power efficiency for both of the fastest growing mobile phone market segments, EDGE and multi-mode 3G.

Global shipments of GPRS / EDGE enabled mobile phones are expected to grow from more than 35 crore units in 2007 to 55 crore units in 2010, according to the market research firm Strategy Analytics. The firm further predicts that the market for 3G mobile phones will soar from 15 crore units in 2007 to more than half a billion in 2010 as consumers demand multi-media content, services, and high speed Internet access.

The SMARTi PM+ is the smallest quad-band RF transceiver for GPRS / EDGE, measuring just 3-by-3-by-0.8mm in a wafer level package. The small size effectively cuts the footprint of the entire EDGE radio by half to just 100 square millimeters, the size of a fingertip, a revolutionary step in cost reduction and miniaturisation for handset OEMs. Based on the mature and proven architecture of the widely-adopted SMARTi PM, the SMARTi PM+ is compatible with existing mobile phone platforms and all major base bands. Two top mobile phone manufacturers have already selected SMARTi PM+ for their latest EDGE handsets.

The SMARTi PM+ supports GPRS Class 12 and EDGE Type 1 with best-in-class sensitivity and EVM performance. The transceiver includes integrated DCXO, loop filter and voltage regulators, and uses small signal polar modulation architecture for compatibility with standard low-cost linear power amplifiers available from all leading PA vendors. Samples are available now and production will start in summer 2007.

The SMARTi UE is the first single-chip UMTS / EDGE RF transceiver that supports the latest DigRF 3.09 specification for the transceiver-to-base band interface. By using the SMARTi UE, which incorporates analogue base band functions such as analogue-to-digital and digital-to-analogue conversion, OEMs can use a single low-cost digital base band IC instead of a more costly and complex analogue-digital base band. Purely digital base bands have a smaller size than analogue-digital base bands, and offer a faster path to even smaller size through Moore's Law.

SMARTi UE supports HSDPA and HSUPA, three UMTS bands out of UMTS Bands I through X, as well as quad-band EDGE. The package measures 6-by-6mm, significantly smaller than the first generation of single-chip W-EDGE and H-EDGE transceivers, which typically measure 7-by-7mm or more. With external components, the complete radio solution with SMARTi UE measures approximately 400 square millimeters, about half the size of previous solutions.

With support for multi-media features through HSDPA / HSUPA, and with the ability to operate in frequency bands around the globe, SMARTi UE is the perfect device for new low cost 3G multi-media handsets. Infineon has shipped samples of the SMARTi UE to tier one mobile phone manufacturers, and will begin production in the second half of 2007.
