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.

Radiation Exposure Statement
Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and
used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
