The RFFM4558A front end module (FEM) for Wi-Fi 802.11a/n/ac systems. It consists of an integrated PA, SPDT Switch and LNA. The small form factor and integrated matching minimizes layout area in the application and reduces the number of external components. It includes integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation. This FEM is ideal for access points, wireless routers, residential gateways and the internet of things.
