Sichuan AI-Link Technology Co., Ltd. page 4 of 17 1. Introduction WF-M668-UWP1 is based on MT7668AUN,complied with IEEE 802.11ab/g/n/ac dual-band WIFI subsystem and a Bluetooth subsystem.. 1.1 RF module Overview The general HW architecture for the module is shown in Figure 1. This WLAN Module design is based on MTK MT7668AUN. It is a highly integrated single-chip MIMO(Multiple In Multiple Out) Wireless LAN (WLAN) USB2.0 network interface controllercomplying with the 802.11n specification. It combines a MAC, a 2T2R capable baseband,and RF in a single chip. The MT7668 provides a complete solution for a highthroughput performance wireless client.The Bluetooth subsystem contains the Bluetooth radio,baseband,link controller.It also uses the 32-bit RISC MCU for the Bluetooth protocols.
