Introduction

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.

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
• Supply voltage: 2.7 - 3.0 V
• 3 -Wire bus programmable
• Low external component count
• Temperature range -25 to 85°C
• P-VQFN-40 leadless package
• 6.5×5.5 mm, 0.5 mm pitch
• Integrated synthesizers
• Direct conversion receiver
• Integrated channel filter
• Integrated DC-offset compensation
• Direct modulation transmitter
• Integrated VGA Dynamic range > 85 dB

Applications

• UTRA FDD standard
• Power class 3
• Fixed and variable duplex
• Compressed mode
• Dual-receive
• Cellular phones
• PDAs and handhelds
