RFFM4204 WiFi 802.11b/g/n/ac Front End Module 2.4GHz to 2.5GHz The RFFM4204 provides a complete solution in a single front end module (FEM) by integrating the power amplifier (PA), low noise amplifier (LNA) with bypass, power detector, a Single Pole Double Throw (SPDT) switch, and some filtering for harmonic rejection. The 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 manufacturing cost. The RFFM4204 is provided in a 6.0mm X 6.0mm X 0.9mm 24-pin laminate package. The FEM meets or exceeds the RF front end needs of IEEE 802.11b/g/n/ac WiFi RF systems.
