“As mMIMO radio functionality grows in complexity, more specialized silicon approaches are required,” said
Together, the RadioVerse Transceiver SoC and the OCTEON 10 Fusion processor support the entire signal chain with unmatched RU system efficiency. The ADRV9040 RadioVerse Transceiver SoC includes substantial digital capabilities including linearization algorithms for boosting power amplifier efficiency and performance, as well as digital channel filters which reduce interface rates. The OCTEON 10 Fusion 5G baseband processor has specialized accelerators optimized for efficiently processing complex beamforming algorithms, along with dedicated processors for the low PHY baseband which can be configured for the various O-RAN split 7.2x configurations.
“Infrastructure vendors face many challenges when developing O-RAN mMIMO radio units, including access to optimized semiconductors,” said
“Marvell is pleased to collaborate with ADI in taking mMIMO radios to the next level,” said
The reference design, which is expandable to support a 64T64R configuration, supports 32 transmit and receive antennas (32T32R) with 400 MHz of operational bandwidth and 300 MHz of instantaneous bandwidth. The OCTEON 10 Fusion 5G baseband processor and RadioVerse SoC leverage hardware accelerators as well as the industry-leading RF and digital baseband process nodes shipping commercially—16 nm and 5 nm respectively—delivering up to 40% reduction in energy consumption per bit as compared over the previous generation. The platform enables Network Energy Savings (NES) modes, which deliver additional power savings.
