SG901-1071 Miniature Wi-Fi Radio
Overview
The SG901-1071 Module is a single chip based
802.11b/g/n WLAN radio for embedded, low-
power and extremely small form factor mobile
applications. The product conforms to the IEEE
802.11b, g, and n protocols operating in the
2.45GHz ISM frequency band supporting
802.11n modulations up to 72.2Mbps, all OFDM
modulations, and all mandatory 802.11b
modulations.
The SG901-1071 is a fully integrated wireless
radio including RF Synthesizer/VCO, high-speed
data converters, digital baseband processor,
onboard MAC and PHY processors, Power
Management, Power Amplifier, and LNA.
An on-board EEPROM stores calibration data
for alignment-free integration.
Bluetooth integration features of the radio are
made available.
An on-board crystal and filter simplify system
integration. Just add one 1.8V regulator, 3.3V
Power, Antenna, and host communications. For
maximum flexibility, the SG901-1071 can
optionally accept a wide range of external
reference clock frequencies.
Host control is provided by either an SDIO or
SPI interface.
