ADI' Transceiver and Marvell' baseband powered 5G radio unit
To address market requirements of ongoing shift towards open RAN, chipmakers Marvell and Analog Devices have announced advanced 4G/5G radio unit (RU) design.
The resulting complete system-level hardware reference designs, will be based on Analog Devices' latest transceiver tech and programmable digital front-end and Marvell's baseband silicon to handle beamforming and a lower L1 software supporting O-RAN split 7.2. Developed in collaboration with Benetel, prototypes are slated for second half of 2021.
This solution supports high antenna counts and multi-gigabit per second throughput for both integrated RAN and Open RAN deployments, and provide native support for O-RAN split 7.2x functionality. ADI-Marvell solution will help OEMs to develop solutions where they can increase the capacity of existing radio sites.
“Our goal in joining with ADI in this effort was to provide a complete, open standards-based RU platform, one that leverages what each company does best,” said Raj Singh, Executive Vice President and General Manager of Marvell’s Processor Business Group. “We wanted to minimize the amount of silicon required to deliver massive MIMO RU solutions capable of supporting 32T32R performance, along with beamforming and DFE functions. ADI’s transceiver solutions align perfectly with our RU and digital unit baseband offerings – it’s exactly what the industry has been seeking in next generation RU designs.”
“The demand for much higher capacity radio units is exploding,” said Joe Barry, Vice President of the Wireless Communications Business Unit at ADI. “Together with Marvell, we are able to get ahead of the curve and help the industry transition to 32T32R – or even higher capacity – radio units. At the same time, by providing differentiated radio architectures and algorithms we are allowing the operators to effectively manage both their capital and operating expenses.”
