WF-M638G-UWP1

IEEE 802.11b/g/n 2T2R USB WIFI Module&BT2.1+EDR/4.2/5.0

1. Introduction

WF-M638G-UWP1 module design is based on Mediatek MT7638GUN solution, The MT7638GUN is a
highly integrated single chip which has built in a 2x2 dual-band wireless LAN radio and Bluetooth radio.
It includes Bluetooth EDR and LE radio which complies with Bluetooth v2.1+EDR, v4.2, and v5.0.
The Module is a highly integrated MAC/BBP and 2.4GHz PA/LNA single chip which supports a 300Mbps
PHY rate. The Module is designed to support standard-based features in the areas of security, quality of
service, and international regulations, giving end users the greatest performance anytime and in any
circumstance. This documentation describes the engineering requirements specification.

1.1 RF module Overview

The general HW architecture for the module is shown in Figure 1. This WLAN Module design is based
on Mediatek MT7638GUN. It is a highly integrated single-chip MIMO(Multiple In Multiple Out) Wireless
LAN (WLAN) network interface controller complying with the 802.11 specification and Bluetooth over
USB interface. It combines a MAC, a 2T2R capable baseband, and RF in a single chip. An intelligent
Wi-Fi/Bluetooth coexistence algorithm is implemented to provide the best harmonized Wi-Fi and
Bluetooth radio performance.
