Filters: AKF-1938
AKF-1938 3.8 GHz IF BAW Filter
Akoustis’ AKF-1938 is a high performance, ultra-small passband BAW Filter targeting 5G infrastructure, radar and general-purpose applications. The 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. The AKF-1938 is assembled in hermetic sealed package and is compatible with high volume, lead-free SMT soldering processes.
