Wi-Fi 6E chipset has AdaptivMIMO for fast 6 GHz adoption
ON Semiconductor is sampling its latest QCS-AX2 chipset family that supports the 6-GHz spectrum band based on the enhanced Wi-Fi 6E standard.

Designed with a high performance, flexible architecture to maximize usage of the 6-GHz band, the product family is optimized for high-throughput Wi-Fi 6E applications, such as access points, gateways, and mesh networking solutions for dense environments and underserved areas.

The QCS-AX2 series is built on an integrated baseband and RF (radio frequency) architecture that supports key Wi-Fi 6E features, such as orthogonal frequency-division multiple access (OFDMA), advanced MU-MIMO (Multi-User, Multi-Input, Multi-Output), and 160-MHz channel support for faster speeds, and SmartScan channel selection for maximum band utilization.

The new product portfolio will include the following:

  • QCS-AX2-A12: tri-band (6-GHz/5-GHz/2.4-GHz) with AdaptivMIMO technology supports flexible 8x8 or 4x4 configurations;
  • QCS-AX2-T12: tri-band concurrent 4x4 operation for high performance, cost-effective routers;
  • QCS-AX2-T8: tri-band concurrent 8-stream configurations for mesh nodes and mainstream access points.

As the Federal Communications Commission anticipates the opening of the 6-GHz band in the United States later this year, up to 1200 MHz of newly available spectrum will be designated for Wi-Fi and other unlicensed use. With almost 5 times of spectrum more than the current 2.4-GHz and 5-GHz bands combined, the 6-GHz band is accelerating the development of next generation Wi-Fi 6 applications. While the 6-GHz client ecosystem takes time to build out, Wi-Fi infrastructure devices, such as gateways, routers, and access points will need to continue to support existing dual band (2.4-GHz/5-GHz) clients; infrastructure applications such as 6-GHz backhaul between gateways and mesh nodes will lead deployments.
