1. General Description

The Realtek RTL8812AE is a highly integrated single-chip 802.11b/g/n/ac 2T2R WLAN PCI Express
network interface controller, and RTL8761AU is a integrated Bluetooth 2.1/3/0/4.0 USB interface controller.
It combines a WLAN MAC, a 2T2R capable WLAN baseband, BT Protocol Stack (LM, LL, and LE), BT
Baseband, modem, and WLAN/BT RF in a single module. The RTL8812AE with RTL8761AU provide a
complete solution for a high throughput performance integrated wireless LAN and Bluetooth device.

The RTL8812AE WLAN baseband implements Orthogonal Frequency Division Multiplexing (OFDM) with 1
transmit and 1 receive path and is compatible with the 802.11ac specification. Features include one spatial
stream transmission, short guard interval (GI) of 400ns, spatial spreading, and transmission over 20MHz ,
40MHz and 80MHz channel bandwidth.

For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying (CCK) and
OFDM baseband processing are included to support all 802.11b and 802.11g data rates. Differential phase shift
keying modulation schemes, DBPSK and DQPSK with data scrambling capability, are available, and CCK
provides support for legacy data rates, with long or short preamble. The high-speed FFT/IFFT paths, combined
with BPSK, QPSK, 16QAM, 64QAM and 256-QAM modulation of the individual subcarriers and rate
compatible punctured convolutional coding with coding rate of 1/2, 2/3, 3/4, and 5/6, provide up to 866.6Mbps
for 802.11ac OFDM.

A RTL8812AE built-in enhanced signal detector, adaptive frequency domain equalizer, and a soft-decision
Viterbi decoder help to alleviate multi-path effects and mutual interference in the reception of multiple streams.
Robust interference detection and suppression are provided to protect against Bluetooth, cordless phone, and
microwave oven interference.

Efficient IQ-imbalance, DC offset, phase noise, frequency offset, and timing offset compensations are provided
for the radio frequency front-end. Selectable digital transmit and receive FIR filters are provided to meet
transmit spectrum mask requirements and to reject adjacent channel interference, respectively.

The RTL8812AE WLAN Controller supports fast receiver Automatic Gain Control (AGC) with synchronous
and asynchronous control loops among antennas, antenna diversity functions, and adaptive transmit power
control function to obtain better performance in the analog portions of the transceiver.

The RTL8812AE WLAN MAC supports 802.11e for multimedia applications, 802.11i for security, and

802.11n/802.11ac Draft 2.0 for enhanced MAC protocol efficiency. Using packet aggregation techniques such
as A-MPDU with BA and A-MSDU, protocol efficiency is significantly improved. Power saving mechanisms
such as Legacy Power Save, and U-APSD, reduce the power wasted during idle time, and compensate for the
extra power required to transmit OFDM. The RTL8812AE provides simple legacy and
20MHz/40MHz/80MHz co-existence mechanisms to ensure backward and network compatibility.

The RTL8761AU Bluetooth controller complies with Bluetooth core specification v4.0, and supports dual
mode (BR/EDR + AMP + Low Energy Controllers). It is compatible with previous versions, including v2.1 +
EDR and v3.0 + HS. For BR/EDR, it supports scatternet topology and allows four active links in slave mode,
and seven active links in master mode. For Low Energy, it supports multiple states and allows eight active links
in master mode. The links in BR/EDR and LE can be active simultaneously.
