RFFM8850P Dualband 2.4GHz and 5.0GHz 802.11b/g/n/a/ac Wi-Fi® Switch + LNA Front End Module The RFFM8850P provides a complete dualband integrated Switch + LNA solution in a single Front End Module (FEM) for Wi-Fi® 802.11b/g/n/a/ac and Bluetooth® systems. The ultra-small form factor and integrated matching greatly reduces the number of external components and layout area. The RFFM8850P integrates a 2.4GHz SP3T Transmit/Receive Switch, a 5.0GHz SP2T Transmit/Receive Switch, a 2.4GHz Low Noise Amplifier with bypass mode, and a 5.0GHz Low Noise Amplifier with bypass mode.
