Introduction to the nRF21540 RF FEM for range extension

The nRF21540 RF front-end module (FEM) provides range extension and link robustness improvements to Nordic's nRF52 Series and nRF53 Series SoCs. It supports Bluetooth® Low Energy, Bluetooth mesh, Thread, Zigbee and 2.4 GHz proprietary protocols. In this recording, the product manager for the nRF21540, Pål Kastnes, talks more about the nRF21540 RF FEM and how the nRF21540 Development Bundle (DB) kickstarts development with the nRF21540 RF FEM.
