1. Introduction
AL-7605B-WG-A module design is based on MT7605 solution, The MT7605 is a highly integrated single
chip which has built in a 2x2 dual-band wireless LAN radio. 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 MT7605. It is a highly integrated single-chip MIMO(Multiple In Multiple Out) Wireless LAN (WLAN)
network interface controller complying with the 802.11 specification over USB interface. It combines a
MAC, a 2T2R capable baseband, and RF in a single chip. An intelligent Wi-Fi coexistence algorithm is
implemented to provide the best harmonized Wi-Fi performance.
