    The Qorvo RFFM4252 provides a complete integrated solution in a single front end module (FEM) for Wi-Fi 802.11b/g/n/ac and Bluetooth® systems. The small form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components. The module allows true 5V supply without any modifications to the supply lines and performance is a balance of maximizing on highest linear output power and leading edge throughput while integrating die level filtering for 2nd and 3rd harmonics as well as LO spur rejection are included.

    The RFFM4252 integrates a 2 GHz power amplifier (PA), single pole three throw switch (SP3T) and bypassable low noise amplifier (LNA) into a single device.
