B-LINK ELECTRONIC CO., LTD in shenzhen
1. Introduction
BL-R8812AF1 is based on realtek RTL8812AU, is a WLAN 11ac Dual Band module,
which fully supports the features and functional compliance of IEEE 802.11 a/b/g/n/ac
standards. This documentation describes the engineering requirements specification.
1.1 RF module Overview
The general HW architecture for the module is shown in Figure 1. This WLAN
Module design is based on Realtek RTL8812AU. It is a highly integrated single-chip
MIMO(Multiple In Multiple Out) Wireless LAN (WLAN) USB2.0 network interface
controller complying with the 802.11ac specification. It combines a MAC, a 2T2R
capable baseband, and RF in a single chip. The RTL8812AU provides a complete
solution for a high throughput performance wireless client.

FCC 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 or more 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.
Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment.
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.
