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



WM-BAC-AT-38 is a WiFi 802.11a/b/g/n/ac MIMO with BT4.1 SIP module for any mobile devices. The module is based Qualcomm QCA6174A chip set 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 modes, data rates are expected to reach 800 Mbps or more.

This module also supports concurrent operation of Bluetooth 4.1 for wireless connectivity during browsing or other device applications. Along with both standard and high speed (HS) Bluetooth data rates, Bluetooth low energy modes are also supported.

  • Supports two antenna ports for WLAN MIMO
  • Supports PCIe 2.1 interface for WLAN and UART/PCM for Bluetooth
  • Supports 20/40MHz at 2.4Gz and 20/40MHz or 80MHz at 5GHz
  • Supports multiuser MIMO
  • Supports BT-WLAN coexistence.
  • Operates on a single 3.3V power supply and I/O supply of 1.8V or 3.3V
  • Lead Free design which supporting Green design requirement, RoHS Compliance, and halogen-free.
  • WM-BAC-AT-38_(TOP)
