PMB 5699
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.
General

Supply voltage: 2.7 - 3.0 V 3-Wire bus programmable Low external component count Temperature range -25 to 85C P-VQFN-40 leadless package 6.5 x 5.5 mm, 0.5 mm pitch Integrated synthesizers
Rx

Features

Integration of receive and transmit path - Smallest size - Lowest component count - Less requirements on PCB layout Fully integrated synthesizers - No external tank circuit - No external frequency adjustment required Fully homodyne architecture - No IF (intermediate frequency) stage - No IF-SAW filter - Easiest frequency concept Lowest current consumption - Highest stand-by and talk time Integrated receive channel filter - Reduced baseband efforts Integrated transmit filter - Reduced baseband signal requirements Flexible baseband interface - Supporting various baseband solutions - Various reference frequencies - Adjustable I/Q interface - Flexible 3-wire-bus concept - Supporting multi-mode Lowest external component count - No external components for DC-offset compensation - No external components for channel filtering
Direct conversion receiver Integrated channel filter Integrated DC-offset compensation
Tx

Direct modulation transmitter Integrated VGA Dynamic range > 85 dB
