A10256 5.6 GHz WiFi Coexistence BAW Filter

Akoustis’ A10256 is a high performance, ultra-wide bandwidth BAW RF Filter for use in 5.6GHz WiFi
applications covering U-NII-2C plus U-NII-3 bands. A10256 utilizes Akoustis’ patented, XBAW technology to
deliver differentiated filter performance. This BAW RF filter provides very low insertion loss and meets the
stringent rejection requirements enabling coexistence with U-NII-1 and 2A. This device exhibits high-power
handling capabilities necessary for demanding power requirements of the latest WiFi standards. A10256 uses
standard laminate packaging and is compatible with high volume, lead-free SMT soldering processes.
