Akoustis’ AKF-1938 is a high performance, ultra-small passband BAW Filter targeting 5G infrastructure, radar and general-purpose applications. AKF-1938 utilizes Akoustis’ XBAW technology which provides leading RF filter performance. This BAW filter provides 100 MHz bandwidth, low insertion loss at 3.8GHz and high out of band attenuation. AKF-1938 is assembled in hermetic sealed package and is compatible with high volume, lead-free SMT soldering processes.
