RTL8723AS

Datasheet

solution for a high throughput performance integrated wireless LAN and Bluetooth device.

The RTL8723AS WLAN baseband implements Orthogonal Frequency Division Multiplexing (OFDM)

with 1 transmit and 1 receive path and is compatible with the IEEE 802.11n specification. Features include

one spatial stream transmission, short guard interval (GI) of 400ns, spatial spreading, and transmission over

20MHz and 40MHz bandwidth.

For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying (CCK)

and OFDM baseband processing are included to support all IEEE 802.11b and 802.11g data rates.

Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling capability,
