MaxLinear introduced a fully integrated System on Chip (SoC) for 4G/5G Open RAN (Radio Access Network) radio units (RU) including in Macro, Massive MIMO, and Small Cell applications.
MaxLinear’s Sierra integrates the following sub-systems into a single chip:
- RF Transceiver supporting up to 8 transmitters, 8 receivers, and 2 feedback receivers
- Digital Front End (DFE), powered by MaxLIN™ the industry’s leading digital pre-distortion (DPD) and crest factor reduction (CFR) solution, and supporting digital up-conversion (DUC) and digital down-conversion (DDC) of component carriers
- Low PHY Baseband Processor supporting 5G, 4G, and NB-IoT air interfaces
- Fronthaul Interface compliant with O-RAN Alliance Split 7.2x
“Sierra is an ultimate integration of MaxLinear’s highest performance RF and system technologies. It empowers radio vendors to rapidly and cost effectively develop new platforms with best-in-class size, weight, and power consumption for Open RAN applications,” said Brendan Walsh, Vice President of MaxLinear’s Wireless Infrastructure Group. “In this way Sierra represents a game-changing innovation that will level the playing field for wireless infrastructure vendors and can dramatically accelerate the global rollout of Open RAN without compromise on network performance or cost.”
