4. 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. 1.1 RF module
