Infineon introduces two RF-chips for LTE and 3G


Infineon has introduced two RF-chips for LTE and 3G - SMARTi LU for highest data rates with LTE, and SMARTi UEmicro for low cost 3G devices.SMARTi LU is a highly integrated 2G/3G/LTE multi-mode RF transceiver compliant to 3GPP Rel.7 and Rel.8. It supports up to six 3G and LTE Bands simultaneously with Quad Band GSM/EDGE. Its long feature list includes LTE FDD class 4 (up to 150Mbps downlink, 50Mbps uplink) MIMO Rx diversity (2Rx + 1Tx), HSPA+, HSPA, WCDMA and GSM/GPRS/EDGE. The device is supporting the global spread of HSPA/LTE spectrum throughout a wide variety of bands. With its MIPI DigRF v4 compliant high-speed digital Baseband interface, SMARTi LU sets a milestone towards “all digital” implementation and enables the silicon intensive baseband chips to follow a faster shrink path towards smaller technology nodes such as 32nm and below. SMARTi LU is based on a standard 65nm CMOS technology provided by multiple semiconductor foundries.

The SMARTi UEmicro is a single chip 2G/3G CMOS RF transceiver for the low end segment of the 3G market. It is a cost down version of the proven and widely adopted SMARTi UE with a backward compatible hard- and software interface via DigRF v3.09. With the elimination of external Low Noise Amplifiers (LNA’s) and a simplified co-banded RF frontend without Rx filters SMARTi UEmicro is perfectly matching the mass market requirements for ultra low cost 3G handsets. SMARTi UEmicro delivers exceptional RF performance for up to three of the globally used WCDMA bands plus Dual- or Quad-Band GSM/EDGE at lowest system cost.
