Filters: AKF-1252
AKF-1252 5.2 GHz RF BAW Filter
Akoustis’ AKF-1252 is a high performance, ultra-small passband BAW RF Filter for use in 5.2GHz WiFi applications covering U-NII 1 plus 2A bands. The AKF-1252 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 2C and 3. This device exhibits high-power handling capabilities necessary for demanding power requirements of the latest WiFi standards. The AKF-1252 uses standard laminate packaging and is compatible with high volume, lead-free SMT soldering processes.
