The Qorvo® RFFM8211 is an integrated front end module (FEM) designed for Wi-Fi 802.11b-ac and Bluetooth® systems. The ultra-small form factor and integrated matching minimizes layout area in the application.
Performance is focused on optimizing the PA for a supply voltage range from 4.2 to 3 V that balances linear performance vs a voltage drop inherent in battery operated systems. Capable for 5 V operation as well . A low loss path for bi-directional transmit and receive of Bluetooth® is integrated in. Integrated die level filtering for 2nd and 3rd harmonics as well as 5 GHz rejection for DBDC operation are included. The RFFM8211 integrates a 2.4 GHz power amplifier (PA), regulator, single pole three throw switch (SP3T), bypassable low noise amplifier (LNA) and DC power detector into a single device.
