SMARTi U Single-Chip
W- C D M A / U MTS Tra nsce i ve r
SMARTi U – First Single-Chip
U M T S / W - C D M A R F -Tr a n s ce i v e r
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.
