NanoSemi and XiIinx Demonstrate Ultra-Wide Band MIMO Digital Front End Using Zynq UltraScale+ RFSoC for 4.5G and 5G Infrastructure at MWC 2018

Solution processes over 8 MIMO layers and 200MHz of signal bandwidth in a single chip.

Multi-carrier LTE

NanoSemi and Xilinx will showcase the power of its digital front-end collaboration based upon the Xilinx® Zynq® UltraScale+™ RFSoC.  An interactive demonstration will highlight NanoSemi’s machine learning based linearization technology, which is uniquely capable of linearizing the highly nonlinear Doherty-class power amplifier.  The demonstration is open to the public in the Xilinx meeting room (Hall 5-L14MR) on Monday, February 26, Wednesday, February 28 and Thursday, March 1 from 9 to 10:30 AM and 12.30 to 1.30 PM.   

The Xilinx- NanoSemi collaboration will showcase technology that exceeds 3rd Generation Partnership Project (3GPP) 4.5G and 5G adjacent channel leakage ratio, error vector magnitude, and other specifications. A wideband linearizer, consuming only a fraction of the Zynq UltraScale+ RFSoC resource, will simultaneously linearize 8 radio frequency Doherty amplifiers supporting 200MHz of signal bandwidth using various LTE and 5G carrier configurations in the IMT 2020 designated mid band (3400–3600MHz).

Zynq® UltraScale+™ RFSoCs integrate multi-giga-sample RF data converters and soft-decision forward error correction (SD-FEC) into an All Programmable SoC architecture. Complete with an ARM® Cortex™-A53 processing subsystem, UltraScale+ programmable logic, and the highest signal processing bandwidth in a Zynq UltraScale+ device, the new family provides a comprehensive RF signal chain for wireless, cable access, test & measurement, early warning/radar, and other high-performance RF applications. Analog and digital functionality are integrated on a single chip, resulting in unique configurability across the signal chain, reduced power consumption, smaller form factor, as well as a simplified design process. Zynq UltraScale+ RFSoCs address the current massive MIMO compute and integration requirements of 5G New Radio (NR) while providing flexibility for future 3GPP 5G NR standard updates.
