Overview: DRAFT DRAFT RFFM8511
4.9GHz to 5.85GHz 802.11a/n/ac WiFi Front End Module The RFFM8511 provides a complete integrated solution in a single front end module (FEM) for WiFi 802.11a/n/ac systems. The ultra-small factor and integrated matching minimizes layout area in the customer’s application and greatly reduces the number of external components. This simplifies the total front end solution by reducing the bill of materials, system footprint, and manufacturing cost. The RFFM8511 integrates a 5GHz power amplifier (PA), single pole double throw switch (SP2T), LNA with bypass, and a power detector coupler for improved accuracy. The device is provided in a 2.5mm x 2.5mm x 0.40mm, 16-pin QFN package. LNA_EN C_RX 16 15
