    The Qorvo RFFM4251 provides a complete integrated solution in a single front end module (FEM) for WiFi 802.11b/g/n/ac and Bluetooth® systems. The ultra-small form factor and integrated matching greatly reduces the number of external components and layout area in the customer applications. This simplifies the total front end solution by reducing the bill of materials, system footprint, and manufacturing cost. The RFFM4251 integrates a 2.5GHz power amplifier (PA), a low noise amplifier (LNA), a power detector coupler for improved accuracy, and a Single Pole 3-Throw (SP3T) switch.
