Reference design reduces time to market and risk for radio designers

An integrated open radio unit (O-RU) reference design by Analog Devices enables radio designers to reduce risk and time to market, providing the optical front haul to RF. It also allows hardware and software customisation for macro and small cell radio units. It uses technologies that drive 4G and 5G RU requirements and includes support for all sub 6GHz band and power variants, including multi-band applications, added Analog Devices. 

The ADRV904x-RD O-RU reference design has been introduced to meet the ever more stringent timeline for O-RUs in tandem with more demanding and complex operator requirements. It provides the radio unit developer with comprehensive collateral resources, said the company, freeing designers to focus on innovation and differentiation.

The ADRV904x-RD O-RU reference design platform includes ADI’s fifth generation 8T8R RadioVerse SoC with digital front end including digital pre-distortion (DPD). ADI’s commercial O-RAN 7.2a IP stack is hosted on Intel’s Agilex 7 F-series FPGA.

The platform has been tested with Radisys Layer 2/3 software running on Intel FlexRan server hardware for 8T8R (eight transmit, eight receive) macro deployment scenarios. 

The O-RU radio platform is showcased at MWC 2023 (27 February to 02 March) in Barcelona, Spain, at ADI’s booth in Hall 2- 2B18.

Analog Devices combines analogue, digital, and software technologies for products that drive digitised factories, mobility and digital healthcare, combat climate change, and connect humans and the world, said the company.
