C BT RX N/C C RX GND PA EN ANT TX RFFM4203 RFFM4203 3.0V to 5.0V, 2.4GHz to 2.5GHz 802.11b/g/n/ac WiFi Front End Module Package: Laminate, 16-pin, 3.0mm x 3.0mm x 1.05mm The RFFM4203 provides a complete integrated solution in a single front end module (FEM) for WiFi 802.11b/g/n/ac and Bluetooth systems. Features The ultra-small form factor and integrated matching greatly reduces the Integrated 2.4GHz to 2.5GHz number of external components and layout area in the customer b/g/n/ac Amplifier, LNA with Bypass Mode, SP3T Switch, and application. This simplifies the total front end solution by reducing the bill Power Detector Coupler of materials, system footprint, and manufacturability cost. The Single Supply Voltage 3.0V to 5V RFFM4203 integrates a 2.4GHz to 2.5GHz power amplifier (PA), low P = 21.5dBm, 5V <3% Dynamic noise amplifier (LNA) with bypass mode, power detector coupler for OUT EVM improved accuracy, and some filtering for harmonic rejection. The P = 19dBm, 3.3V <3% Dynamic OUT device is provided in a 3mm x 3mm x 1.05mm, 16-pin package. This EVM module meets or exceeds the RF front end needs of IEEE 802.11b/g/n/ac WiFi RF systems.
