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
RTL8812AEBT Combo module User Manual
2
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.

2.3. Warning
3.5.1 Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with minimum distance 20cm between the radiator & your body.
Operations in the 5.15-5.25GHz band are restricted to indoor usage only.
IEEE 802.11abgn 2.4G operation of this product in the U.S.A. is firmware-limited to channels 1 through 11.
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and
2) This device and its antenna(s) must not be co-located with any other transmitters except in accordance
with FCC multi-transmitter product procedures.
3) For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band by supplied
firmware programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain
