Details Information


Fn-Link Technology would like to announce a high performance, with small SMT package module, which has all of the Wi-Fi and Bluetooth functionalities. The highly integrated module makes the possibilities of web browsing, VoIP, Video transmission, Bluetooth headsets applications. With seamless roaming capabilities and advanced security, also could interact with different vendors’ 802.11a/b/g/n/ac/ax 2x2 Access Points in the wireless LAN. 

The wireless module complies with IEEE 802.11 a/b/g/n/ac/ax 2x2 MIMO standard and it can achieve up to a speed of 1774.5Mbps (2x2 80MHz 11ax + 2x2 40MHz 11ax DBS). The integrated module provides PCIe interface for Wi-Fi, UART/PCM interface for Bluetooth. 

This compact module is a total solution for a combination of Wi-Fi and Bluetooth V5.1 technology. The module is specifically developed for all portable devices.



Highly integrated wireless local area network (WLAN) system-on-chip (SOC) for 2.4G/5G 802.11ax WLAN applications.

Compliant with IEEE 802.11a/b/g/n/ac/ax.

Supports 2x2 Multi-User Multiple-Input Multiple-Output (MU-MIMO).

Dual Band Simultaneous (DBS) with dual MAC, up to 1774.5 Mbps data rate (2x2+2x2 11ax DBS) Supports 20/40MHz at 2.4GHz and supports 20/40/80MHz at 5GHz.

Dynamic Frequency Selection (DFS, radar detection).

Offloading traffic for minimal host utilization at 11ac/ax speeds.

Supports Bluetooth for class1 and class2 power level transmissions without requiring an external PA.

Small SMT LGA package for placement.
