Infineon releases new LTE and 3G RF chips SMARTI LU and SMARTI UEmicro
Infineon Technology announced the launch of the second-generation LTE RF transceiver sample with the highest transmission rate-SMARTI LU single-chip RF transceiver, and 3G RF transceiver SMARTI UE series third-generation SMARTi UEmicro, suitable for the lowest Cost 3G device.
The SMARTi LU RF transceiver uses a 65-nanometer CMOS process and can provide 2G / 3G / LTE with a DigRF digital broadband interface. The highest data transmission rate in an LTE network is up to 150Mbps. The SMARTi UEmicro RF chip is optimized for the lowest cost 3G design, so that the dual-band WCDMA / EDGE RF system e-BoM cost can be reduced to only $ 6.50, which is a significant reduction of about 40 compared to existing solutions on the market. %.
SMARTi LU is a highly integrated 2G / 3G / LTE multimode RF transceiver that complies with 3GPP Rel.7 and Rel.8, and can support up to six 3G and LTE bands simultaneously with quad-band GSM / EDGE. SMARTi LU has many features, including LTE FDD level 4 (up to 150Mbps downlink rate, 50Mbps uplink rate) MIMO Rx diversity (2Rx + 1Tx), HSPA +, HSPA, WCDMA and GSM / GPRS / EDGE.
SMARTi LU can also support the worldwide HSPA / LTE specifications in a variety of frequency bands, and has a high-speed digital baseband interface that conforms to MIPI DigRF v4, which not only makes a big step toward "all-digital" applications, but also makes the silicon crystal dense Baseband chips accelerate towards smaller technology nodes such as below 32 nanometers.
SMARTi UEmicro is a 2G / 3G CMOS single-chip RF transceiver designed specifically for the low-end groups of the 3G market. It is the low-cost version of Infineon's SMARTi UE series, and is backward compatible with hardware and software interfaces through DigRF v3.09. SMARTi UEmicro abandons the external "low-noise amplifier" (LNA), and the simplified common-frequency RF front-end also omits the Rx filter, which can meet the broad market demand for ultra-low-cost 3G mobile phones. SMARTi UEmicro can support three global WCDMA frequency bands as well as dual-band and quad-band GSM / EDGE, providing excellent RF performance at the lowest system cost.
SMARTi UEmicro will provide customer samples from the second quarter of 2009, and mass production is expected by the end of 2009.
