SMARTi UE2 RF transceiver

Infineon Technologies AG is sampling the SMARTi UE2 multi-band HSPA+/Edge/GPRS RF transceiver for mobile devices. Its digital architecture reduces the number of power amplifiers from five to one and integrates all LNAs and interstage filters. This leads to remarkable improvements for next generation smart phones: RF PCB area shrinks by 40 percent, cost of ownership reduces by 40 percent and current consumption economizes by more than 25 percent compared to today's solutions.

SMARTi UE2 supports quad-band Edge and six-band HSPA+ for global roaming and best area and indoor coverage. It boosts data rates up to 28.8Mbit/s in downlink and 11.5Mbit/s in uplink at highest signal quality with Rx Diversity and MIMO. SMARTi UE2 and all the RF front-end components are controlled through a standardized digital DigRF V3.09 interface. Built-in routines and a High Level Command programming allow shortest calibration time and very simple system integration of the RF subsystem. The interface and programming model is backward compatible to the successful SMARTi UE family and matches perfectly to Infineon HSPA and HSPA+ Baseband modems X-GOLD 61x and X-GOLD 62x.

"The SMARTi UE2 provides outstanding benefits for all the major key performance indicators: cost, size, current consumption and RF performance," says Stefan Wolff, VP of the wireless solutions division and general manager of the smart phone and RF business at Infineon. "Our proven leadership in RF will enable our customers to create new smart phones and mobile Internet devices with extremely flexible form factors and extended battery life time."

Infineon offers a complete form-factor reference design with co-developed RF front-end components like power amplifiers and switches from leading component suppliers reducing efforts and time-to-market for customers. SMARTi UE2 samples have been provided to lead customers and mass production is scheduled to start in fourth quarter 2010.
