ON Semiconductor is sampling its QCS-AX2 chip family, which supports the 6-GHz spectrum band based on the Wi-Fi 6E standard. Built on an integrated baseband and RF architecture, the QCS-AX2 devices are optimized for high-throughput Wi-Fi applications, such as access points, gateways, and mesh networks for dense environments and underserved areas.

The QCS-AX2-A12 is a triband (6 GHz, 5 GHz, 2.4 GHz) device with adaptive MIMO that supports flexible 8×8 or 4×4 configurations. Adaptive MIMO techniques allow network operation 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 series also includes the QCS-AX2-T12, which offers triband concurrent 4×4 operation for high-performance routers, and the QCS-AX2-T8, which enables triband concurrent 8-stream configurations for mesh nodes and mainstream access points.

Devices in the QCS-AX2 series support key Wi-Fi 6E features, including orthogonal frequency-division multiple access (OFDMA) and multi-user, multi-input, multi-output (MU-MIMO) technologies that enable simultaneous bidirectional communication between an access point and end users. They also leverage ultra-wide 160-MHz channels for faster speeds and SmartScan channel selection for maximum band utilization.

ON Semiconductor is now sampling the QCS-AX2 components to customers.
