    The RFFM4558A provides a complete integrated solution in a single front end module (FEM) for Wi-Fi 802.11a/n/ac systems. The small form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components.

    Performance is focused on conserving power consumption while maintaining the highest linear output power and leading edge throughput.

    Integrated die level filtering for 2nd and 3rd harmonics as well as 2.4 GHz rejection for DBDC operation are included

    The RFFM4558A integrates a 5 GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) into a single device.
