    Qorvo's RFFM4203 provides a complete integrated solution in a single Front End Module (FEM) for Wi-Fi 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 application. This simplifies the total Front End solution by reducing the bill of materials, system footprint, and manufacturability cost. The RFFM4203 integrates a 2.4GHz to 2.5GHz Power Amplifier (PA), Low Noise Amplifier (LNA) with bypass mode, power detector coupler for improved accuracy, and some filtering for harmonic rejection. The device is provided in a 3mm x 3mm x 1.0mm, 16-pin package. This module meets or exceeds the RF Front End needs of IEEE 802.11b/g/n/ac Wi-Fi RF systems.
