RFFM4203

3.0V to 5.0V, 2.4GHz to 2.5GHz

802.11b/g/n/ac WiFi Front End Module

The RFFM4203 provides a complete integrated solution in a single front

end module (FEM) for WiFi 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 1.05mm, 16-pin package. This

module meets or exceeds the RF front end needs of IEEE

802.11b/g/n/ac WiFi RF systems.
