1. Introduction

M632USA1 module design is based on Mediatek MT7632U solution,

The MT7632U 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, v3.0, and v4.0+BLE.
The Module is a highly integrated MAC/BBP and 2.4/5GHz 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  MT7632U.  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.
