RFFM4252 Wi-Fi Front End Module General Description The RFFM4252 provides a complete integrated solution in a single front end module (FEM) for Wi-Fi 802.11b/g/n/ac and Bluetooth systems. The small form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components. 16 Pad 3x3mm Laminate Package The module allows true 5V supply without any modifications to the supply lines and performance is a balance of Product Features maximizing on highest linear output power and leading nd edge throughput while integrating die level filtering for 2 24122484MHz rd and 3 harmonics as well as LO spur rejection are included P = +21dBm MCS8 HT40 -35dB Dynamic EVM OUT POUT = +22dBm MCS7 HT20/40 -30.5dB Dynamic EVM The RFFM4252 integrates a 2 GHz power amplifier (PA), P = +25dBm 802.11b DSSS 1MBps Spectral Mask single pole three throw switch (SP3T) and bypassable low OUT noise amplifier (LNA) into a single device.
