ON Semiconductor announced sampling of its new 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 new product family is optimized for high-throughput Wi-Fi 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 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

ON Semiconductor’s Wi-Fi 6E solutions are designed to accommodate the transition to the 6 GHz band with AdaptivMIMO technology while addressing mainstream 6 GHz applications. A Wi-Fi 6E infrastructure device with AdaptivMIMO allows the network to operate in the 5 GHz or 6 GHz band depending on the clients present in a subscriber’s home network to maximize performance, coverage, and utilization. The QCS-AX2 series provides the Wi-Fi performance and connectivity in congested environments to multiple devices that applications demand.
