Courtesy of Qorvo QPF7221 Front End Module
The Qorvo QPF7221 is a compact front end module (FEM) for Wi-Fi 802.11b/g/n/ac/ax systems. The FEM integrates a 2 GHz power amplifier (PA), SPDT switch and bypassable low noise amplifier (LNA) and an Rx BAW filter into a single device. It 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 requires a 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 small form factor and integrated matching minimizes layout area in the application and greatly reduces the number of external components.
