QPF7221

2.4 GHz Wi-Fi Front End Module with integrated Coexistence BAW

The QPF7221 provides a complete integrated solution in a single front end module (FEM) for Wi-Fi 802.11b/g/n/ac systems. The small form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components. The FEM allows true 5V supply without any modifications to the supply lines and performance is a balance of maximizing on highest linear output power and leading edge throughput. The FEM also provides state of the art LTE coexistence Rx immunity for maximum range and coverage by integrating high performance temperature stable BAW filtering on receive chain. The QPF7221 integrates a 2GHz power amplifier (PA), single pole two throw switch (SP2T) and bypassable low noise amplifier (LNA) and an Rx BAW filter into a single device.
