PRODUCT DESCRIPTION

SM02BD is a small size and low profile of WiFi+BT combo module with LGA (Land-Grid
Array) footprint, board size is 12mm*12mm with module height of 2mm. It can be easily
manufactured on SMT process and highly suitable for tablet PC, ultra book, mobile
device and consumer products. It provides GSPI/SDIO interface for WiFi to connect
with host processor and high speed UART interface for BT. It also has a PCM interface
for audio data transmissio n with direct link to external audio codec via BT controller.
The WiFi throughput can go up to 150Mbps in theory by using 1x1 802.11n b/g/n MIMO
technology and Bluetooth can support BT2.1+EDR/BT3.0 and BT4.0.

SM02BD uses Realtek RTL8723BS, a highly integrated WiFi/BT single MODULE based on
advanced COMS process. RTL8723BS integrates whole WiFi/BT function blocks into
a chip, such as SDIO/UART, MAC, BB, AFE, RFE, PA, EEPROM and LDO/SWR, except
fewer passive components remained on
PCB.

PRODUCT FEATURES

 Operate at ISM frequency bands (2.4GHz)
 GSPI/SDIO for WiFi and UART for Bluetooth
 IEEE standards support: IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11d, IEEE

802.11e, IEEE 802.11h, IEEE 802.11i

 Fully Qualified for Bluetooth 2.1 + EDR specification including both 2Mbps and

3Mbps modulation mode

 Fully qualified for Bluetooth 3.0
 Fully qualified for Bluetooth 4.0 Dual mode
 Full –speed Bluetooth operation with Piconet and Scatternet support.
 Enterprise level security which can apply WPA/WPA2 certification for WiFi.
 WiFi 1 transmitter and 1 receiver allow data rates supporting up to

150 Mbps downstream and 150 Mbps upstream PHY rates

 For WiFi/BT, it uses fixed path for WiFi and BT, which means one antenna assigned

for WiFi and the other is assigned for BT.
