MCS9(866.7Mbps)
1.1 RF module Overview
The general HW architecture for the module is shown in Figure 1. This WLAN Module design is based
on Marvell 88W8897. It is a highly integrated single- chip MIMO(Multiple In Multiple Out) Wireless LAN
(WLAN) network interface controller complying with the 802.11ac specification over SDIO,PCIE,USB
and UART interface.. It combines a MAC, a 2T2R capable baseband, and RF in a single chip. The
88w8897 provides a complete solution for a high throughput performance wireless client .
