Lattice & Affarii LogosRRU Solutions for LatticeECP3 FPGAs Webcast

In the wireless infrastructure market, carriers are looking to future proof their investments when deploying 3G and 4G technologies. Universal platforms offer cost and power benefits while enabling flexible deployment with easy upgradeability. The combination of the industry-leading low cost, low power LatticeECP3 FPGA and the unique digitalTRX™ technology from Affarii Technologies, Ltd. provides an unprecedented RRH solution that includes Digital Up/Down Converter (DUC/DDC), Crest Factor Reduction (CFR) and Digital Pre-Distortion (DPD) functionality. Additionally, Lattice provides CPRI/OBSAI and Ethernet technology implemented on the LatticeECP3's low-cost 3G SERDES transceivers.

A fully-integrated RRH solution is now available, providing baseband processing for up to two transmit and four receive antennas on a single silicon device, with each antenna supporting four carriers and 20 MHz of modulation bandwidth. When used with industry-standard Doherty amplifiers, the digital predistortion provides up to 30 dB of ACLR correction per transmit antenna with PA output efficiencies exceeding 40%. The solution is fully customizable, with end applications including WCDMA, LTE, WiMAX, WiBro, TD-SCDMA and DVB-T/S/H.
