RFFM8250 RFFM8250 2.4GHz to 2.5GHz 802.11b/g/n/ac WiFi Switch + LNA Module Package: QFN, 10-pin, 1.75mm x 1.75mm x 0.33mm The RFFM8250 provides a complete integrated Switch + LNA solution in Features a single Front End Module (FEM) for WiFi 802.11b/g/n/ac and SP3T T/R Switch with Bluetooth Bluetooth systems. The ultra-small form factor and integrated Support matching greatly reduces the number of external components and LNA with Bypass Mode layout area in the customer applications. This simplifies the total front end solution by reducing the bill of materials, system footprint, and Input and Output Matched to 50 manufacturing cost. The RFFM8250 integrates a Single Pole Three Wide Voltage Supply Range Throw (SP3T) Transmit/Receive (T/R) Switch and a 2.5GHz Low Noise Supports WiFi chipsets with Amplifier (LNA) with bypass mode. The device is provided in a 1.75mm Integrated Power Amplifier (iPA) x 1.75mm x 0.33mm 10-pin QFN package.
