The RadioVerse SoC provides radio unit developers with an agile and cost-effective platform to create the most energy efficient 5G RUs in the industry.

Analog Devices Inc.’s RadioVerse System-on-Chip (SoC) series provides radio unit (RU) developers with an agile and cost-effective platform to create the most energy efficient 5G RUs in the industry. The new SoC series provides advanced RF signal processing with expanded digital functionality and RF capacity that greatly improves 5G RU performance and energy efficiency.

The SoCs are the newest addition to ADI’s RadioVerse ecosystem and combine its award-winning Zero IF (ZiF) architecture with significant advances in functional integration and linearization. ADI’s RadioVerse devices are the most widely used software-defined transceivers in 4G and 5G RUs worldwide.

Demand for power efficient RUs is expanding rapidly as global network operators race to deploy 5G infrastructure. With the exponential growth of wireless demand, energy efficiency is a key metric for operators as they seek to reduce their carbon footprint while expanding network capacity. The new RadioVerse SoC series requires very low power compared to alternatives and implements advanced algorithms that deliver optimal RU system efficiency.

The ADRV9040 is the first in the new RadioVerse SoC series. It offers eight transmit and receive channels of 400MHz bandwidth and integrates advanced digital signal processing functions, including carrier digital up-converters (CDUC), carrier digital down-converters (CDDC), crest factor reduction (CFR) and digital pre-distortion (DPD). This expanded signal processing can eliminate the need for a field-programmable gate array (FPGA), thereby reducing thermal footprint, and total system size, weight, power, and cost. The SoC’s DPD algorithms were developed using advanced machine learning techniques and are optimized in close collaboration with major power amplifier (PA) vendors to ease the design burden and deliver best-in-class wide bandwidth performance. The algorithms are fully tested and validated across 4G and 5G use cases, including various PA technology types such as gallium nitride (GaN).

In addition, the ZiF radio architecture simplifies RF filtering and signal chain components, reducing RU cost and development time for band and power variants designs.
