Filters: AKF-1256
AKF-1256 5.6 GHz RF BAW Filter
Akoustis’ AKF-1256 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. The AKF-1256 utilizes Akoustis’ patented, XBAW technology which provides leading RF filter performance. This BAW RF filter provides 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. The AKF-1256 uses standard laminate packaging and is compatible with high volume, lead-free SMT soldering processes.
