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
