USI’s WiFi Combo module has integrate WiFi and Bluetooth technology together to simply design and provide better co-existence performance.



A Wi-Fi 802.11a/b/g/n/ac MIMO with BT4.1 SiP module, WM-BAC-AT-39, is designed for any mobile device. The proposed module will use Qualcomm QCA6174A chipset (also called “Rome 2”), which includes LNA, switch, and internal power amplifier (iPA) for small form factor and optimum performance.

All filters and diplexers will be included in the module to ensure maximum power flatness and optimum VSWR. The module will perform with all legacy hardware having data rates as low as 1 Mbs. When running 802.11 ac in 2 x 2 MIMO mode, data rates are expected to reach 800 Mbps or more.

This chipset also supports the concurrent operation of Bluetooth (Version 4.1) for wireless connectivity during browsing or other device applications. Along with standard and high speed (HS) Bluetooth data rates, Bluetooth low energy modes are also supported. Hardware WAPI acceleration engine, AES, TKIP, WPA and WPA2 are supported to provide the latest security requirement on your network.
