  • Supports almost 5 times more spectrum than the current 2.4 GHz and 5GHz bands combined
  • Provides large coverage and connectivity in congested environments

ON Semiconductor’s new QCS-AX2 chipset family supports the 6GHz spectrum band that is based on the enhanced Wi-Fi 6E standard. Designed with a flexible architecture for leveraging the 6GHz band, the new product family has a high-throughput for Wi-Fi applications, such as access points, gateways and mesh networking solutions for dense environments and remote 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 160MHz channel support for faster speeds, and SmartScan channel selection for maximum band utilization.

The new QCS-AX2 chipset family includes:

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

Developing next-gen WiFi 6 applications

With almost 5 times more spectrum than the current 2.4 GHz and 5GHz bands combined, the 6GHz band is accelerating the development of next-generation Wi-Fi 6 applications. While the 6GHz 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 (2.4GHz/5GHz) clients.

“We are excited about the tremendous opportunities that Wi-Fi 6E opens for the industry. We are in the forefront of building Wi-Fi 6E platforms that enable even better speed, efficiency and performance for the Home, Enterprise, Automotive and IoT segments,” said Irvind Ghai, Vice President of Marketing, Quantenna Connectivity Solutions at ON Semiconductor. “ON Semiconductor is dedicated to innovation in Wi-Fi technology, and will continue to leverage its connectivity excellence to provide end-to-end solutions that accelerate key Wi-Fi 6E ecosystems.”

Optimised for maximum performance

ON Semiconductor’s Wi-Fi 6E solutions allows the transition to the 6GHz band with AdaptivMIMO technology while addressing mainstream 6GHz applications. A Wi-Fi 6E infrastructure device with AdaptivMIMO allows the network to operate in the 5GHz or 6GHz band for maximum performance, coverage and utilization. The QCS-AX2 series provides Wi-Fi performance and connectivity in congested environments to multiple devices that applications demand.

“Our new generation of QCS-AX2 with AdaptivMIMO allows OEMs fast time-to-market with optimized performance across the 3 bands. As Wi-Fi 6E infrastructure proliferates, it will seed the 6GHz ecosystems. Client devices will also benefit from improved efficiency, lower latency and jitter, and less interference, providing better user experience across applications and environments,” said Simon Duxbury, General Manager & Vice President, Quantenna Connectivity Solutions, ON Semiconductor.

ON Semiconductor is now providing the QCS-AX2 solutions to customers.
