NanoSemi’s machine-learning-based linearization technology can linearize the highly nonlinear Doherty-class power amplifier. One of the series of evaluation boards able to demonstrate this feat is the Xilinx Zynq UltraScale+ RFSoC DFE.
The collaborative technology demonstrates how the 3rd generation Partnership Project (3GPP) is exceeded and exceeds 4.5G and 5G adjacent channel leakage, error vector magnitude, and various other specifications. The wideband linearizer consumed only a fraction of the Zynq UltraScale+ RFSoC resources, while simultaneously linearizing 8 radio frequency Doherty amplifiers. The amplifiers support 200MHz of signal bandwidth, utilizing a number of LTE and 5G carrier configurations in the IMT 2020 designated mid-band (3400 – 3600MHz)
Zynq UltraScale+ RFSoCs integrate a multi-giga-sample RF data converter and soft-decision forward error correction (SD-FEC) into an All Programmable SoC architecture. The SoC is equipped with an ARM Cortex-A53 processing subsystem, UltraScale+ programmable logic, and a high signal processing bandwidth in a Zynq UltraScale+ device.
The family of evaluation boards provides a comprehensive RF signal chain for wireless, cable access, test, and measurement, early warning/radar as well as other high-performance RF applications. Analog and digital functionality are integrated on one chip, resulting in configurability across the signal chain, reduced power consumption, smaller form factor, and a simplified design process.
The Zynq UltraScale+ RFSoC addresses the enormous MIMO compute integration requirements of 5G New Radio (NR)while being flexible for future 3GPP 5G NR standard updates.
