Fully adaptive 1 Gbps point to point microwave modem IP for mobile backhaul applications.

The Xilinx 1024QAM Microwave Modem IP is designed for wireless backhaul networks with reliability, timing, and cost constraints. This IP is a fully adaptive, low-footprint, low-power modem solution for indoor and full outdoor point-to-point microwave links. It supports a 1Gbps, single-channel, raw-data throughput and has an integrated digital pre-distortion module.

All integrated versions of the modem are supported by the Zynq™-7000 SoC platform, Artix™ and Kintex™ family of devices. This Xilinx solution for a 1024QAM Microwave Modem conserves considerable PCB board space and power versus competing design solutions. The modem incorporates all PHY layer features including QPSK-1024QAM modulation, 3.5-112MHz bandwidth support, adaptive modulation, adaptive DPD, FEC, I/Q imbalance correction, automatic frequency recovery, and a hybrid decision-directed equalizer. It also features an integrated payload controller and a configuration interface.
