Boost your link budget with a range extender
The range and link robustness of Nordic nRF52 and nRF53 Series SoCs fulfill the requirements of most applications and use-cases, but sometimes adding an RF front-end module (FEM) is the correct choice. An RF FEM increases the range at which two wireless devices can communicate, while also enhancing link robustness. Combining our nRF21540 RF FEM with an nRF52 or nRF53 Series SoC can boost range between 6.3-10x.
In the image above, a regular connection with +8 dBm TX output power is
compared to a +20 dBm TX output power connection with an nRF21540 RF FEM
on both sides. Both the increased TX output power, as well as RX
sensitivity improvements from the nRF21540 help boost the range of the
connection. If using a Nordic SoC with less than +8 dBm TX output power, the range increase is even larger.
Be aware that a +20 dBm TX output power is not allowed in all regions. See the maximum regulatory output power table for more details.
