SG901-1059 802.11 b/g/n Wireless USB Module
Overview
The SG901-1059 is a high speed module
supporting all datarates and the latest standards
including 802.11B/G/N Wi-Fi module with a USB
2.0 interface. This module’s high level of
interoperability and its low cost is desirable for
high volume applications. This product is suited
for many embedded systems able to support
Windows and Linux OS including high
bandwidth applications such as set top box.
SG901-1059 WLAN module is designed to
operate in 2.4GHz ISM frequency band, it
applies a highly integrated MAC/BBP and RF
single chip RT3070 with 150Mbps PHY rate
supporting.
