1.6Gbps low power, low cost, small cell 4G/LTE backhaul modem IP for millimeter-wave applications

Small cell traffic backhaul is a growing challenge as small cells proliferate in 4G/LTE mobile infill situations and for other cellular areas with patchy (or no) coverage. Millimeter-wave backhaul presents one solution to this challenge and Xilinx has just announced IP to support millimeter-wave radio backhaul at data rates to 1.6Gbps with future extensions planned to 10Gbps. The Xilinx 256QAM Millimeter Wave SmartCORE Modem IP solution supports point-to-point and multipoint line-of-sight communications and addresses the needs of both 60GHz and 80GHz radio backhaul.


All integrated versions of the modem are supported by the Zynq-7000 SoC, Kintex FPGAs, and the new Kintex UltraScale device family. The modem incorporates all PHY layer features including QPSK-256QAM modulation, 20-250MHz bandwidth support (optionally up to 500MHz), adaptive modulation, adaptive DPD, FEC, I/Q imbalance correction, automatic frequency recovery, and a hybrid decision-directed equalizer. Both 1GbE and 10GbE interfaces can be used as payload interfaces. You can also use a CPRI interface for wireless fronthaul applications.
