Range extender nRF21 series

Increasing range and link robustness

The range and link robustness of Nordic's nRF52 and nRF53 series SoCs meet the requirements of most applications and use cases, but sometimes adding an RF front-end module (FEM) is the right choice. An RF FEM extends the range over which two wireless devices can communicate, while improving the robustness of the link. Combining the nRF21540 RF FEM with an nRF52 or nRF53 series SoC can increase range by 6.3 to 10 times.

About the nRF21540

The nRF21540 is an RF front-end module that enhances the range and connection robustness of Nordic Semiconductor's short-range wireless portfolio. As a complementary device, the nRF21540 is a "plug-and-play" range extender that provides enhanced link robustness using an integrated power amplifier. It can be used with the nRF52 and nRF53 series advanced multiprotocol wireless SoCs with minimal external component requirements.
