Tune In to Open RAN Design Efficiencies

The RadioVerse® ADRV904x-RD open radio unit (O-RU) reference design platform from Analog Devices, Inc. (ADI) combines essential elements of the open RAN (O-RAN) design process and frees up RU engineers to focus on innovation rather than design hurdles. Combined with a customer supported development process, these O-RAN reference designs help empower engineers to develop unique and differentiated RUs with less risk and a shorter time to market by providing a known and trusted architecture that has been conformance and interoperability tested in multiple O-RAN plugfests and private installations.

A Complete O-RAN Design Solution

The RU platform is a complete solution from the optical fronthaul to RF and allows for hardware and software customization for macro and small cell RUs. The fully integrated platform leverages market-leading technologies that drive advanced 4G and 5G RU requirements and include support for all sub-6 GHz band and power variants, including multiband applications. A massive MIMO platform will be introduced later this year.

This complete O-RAN design and development platform includes ADI’s advanced 8T8R 400 MHz, ADRV904x ADI RadioVerse SoC, and commercial grade and interoperability tested O-RAN 7.2a IP, running on the Intel® advanced node AGF014 Agilex™ FPGA.

A Full 5G Radio Platform for the O-RAN Ecosystem

This radio platform addresses critical power consumption and design challenges of next-generation networks. The ADRV904x with digital front end is the lowest power integrated transceiver, with architecture that reduces RF front-end complexity and relaxes filter requirements. The DFE includes advanced algorithms for digital predistortion (DPD), crest factor reduction (CFR), and channel digital up/downconversion (CDUC/CDDC). The power signal chain is tuned to reduce the signal-to-noise ratio, improving the performance and efficiency of the RU. The full-featured, commercial ready 7.2a O-RAN IP (eCPRI + low PHY) supports LTE, 5G, and NB-IoT.

O-RU Reference Designs

By synchronizing and harmonizing active components on a small signal board, ADI’s O-RU reference designs simplify the development process and significantly shorten the design cycle by eliminating many common design hurdles and minimizing risk.

The reference platform includes standard connectors for flexible PA modules for rapid testing and allows the development of all 4G or 5G bands and power variants from 0.25 W to 60 W. The fully supported, commercial O-RAN 7.2a IP facilitates rapid setup for interoperability testing.

Conformance and Interoperability

ADI’s new radio platform for the 5G O-RAN ecosystem features all the core functionality of the radio unit, including a commercial grade O-RAN 7.2a IP paired with ADI’s next-generation software-defined transceiver. Modular RF front-end connectors support easy testing for a different band, bandwidth, and power level PAs. End-to-end phone calls and video streaming have been completed successfully on the platform. Multiple third-party vendors have tested and proven the platform’s interoperability during various O-RAN alliance plugfests and in private installations connecting through the Radisys DU/CU stack with Intel FlexRAN™.
