The RFFM4501 provides a complete integrated solution in a single Front End Module (FEM) for WiFi 802.11a/n/ac systems. The ultra small form factor and integrated matching minimizes the 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 manufacturability cost. The RFFM4501 integrates a Power Amplifier (PA), Single Pole Double Throw switch (SPDT), LNA with bypass, and a power detector coupler for improved accuracy. The device is provided in a 3mm x 3mm x 1.0mm, 16-pin laminate package. This module meets or exceeds the RF Front End needs of IEEE 802.11a/n WiFi RF systems.
