joint of the circuit on the PCB. The gain of the external antenna is 2dB, the length of the antenna is 200mm, the
internal structure is copper tube structure. A resistance of 0R is added between the module and the antenna at R8
to ensure that the impedance of the connection between the module and the antenna reaches 50R.J1 position on
PCB is the position of external antenna.
9. Software introduction
BL-8822SSA3 module design is based on RTL8822BS-CG solution, The Realtek
RTL8822BS-CG is a highly integrated single-chip that support 2-stream 802.11ac solutions with
Multi-user MIMO
(Multiple-Input, Multiple-Output) with integrated Bluetooth 2.1/3.0/4.1 controller,SDIO (SDIO
1.1/2.0/3.0) interface, and HS-UART mixed interface. It combines a WLAN MAC, a 2T2R
capable WLAN baseband, and RF in s single chip. The RTL8822BS-CG provides a complete
solution for a high-performance integrated wireless and Bluetooth device.
10. FCC Compliance Warning Statements:
If the FCC identification number is not visible when the module installed in the host, then the
outside of the device into which the module was installed in must also display a label referring
to the enclosed module. This exterior label can use wording such as the following:“
"Contains Transmitter Module FCC ID:2AL6K-8822SSA3" or “ Contains FCC ID:2 AL6K-8822SSA3”
