SMARTi U – First Single-Chip

UMTS/W-CDMA RF-Transceiver

Infineon has designed the first single-chip UMTS/ W-CDMA RF-transceiver IC SMARTi U to be used in mobile applications according 3GPP (FDD, 2100 MHz) requirements. SMARTi U (PMB 5699) offers lowest component count and smallest PCB area at lowest current consumption. The full homodyne architecture and flexible control concept reduces significantly implementation efforts and time-to-market.
