WiBear11n Data Sheet Version 1.18 Reference Design Overview Reference design shows how to connect a WiBear11n module to the host controller. WLAN and Bluetooth (BT3.0 HS + EDR) may be connected to the host simultaneously over the SDIO bus. The layout is equipped with the possibility to either use an onboard antenna or an external antenna connected via coaxial connector by means of setting of jumper R7 or R8. Host interface voltage can also be changed by jumper J6.

WiBear11n Data Sheet Version 1.18 Mounting process The WiBear11n is a surface mount module supplied on a 6-layer FR4-type PCB with gold plated connection pads and produced in a lead-free process with a lead-free soldering paste. The warpage of the PCB is max. 0,75% according to IPC-A-610E. The thickness of solder resist on the host PCB top side and the WiBear11n bottom side must be considered for the soldering process. Modules rated at moisture sensitivity level 3.
WiBear11n Data Sheet Version 1.18 Installation and Regulatory Information General The purpose of this guide is to explain how to integrate the WiBear11n module into the end product. The module has to be installed and used in accordance with the technical instructions provided by the manufacturer. The module may only be implemented in the configuration that was authorized.
WiBear11n Data Sheet Version 1.18 The internal / external antenna(s) used for this module must provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. NOTE: The outside of final product that contain a WiBear11n module must display in a user accessible area a label referring to the enclosed module.
