nRF52840 Dongle

hiper-global

As I understand from the datasheets nRF52840 Dongle contains an internal antenna. What is the maximum distance that can be received with the internal antenna? Do you have a similar product to which you can connect an external antenna to increase the reception range?

    Hi,

    It is not possible to determine the maximum distance as it will rely on several external factors. The antenna on the dongle is a meander antenna which has less gain , and lower bandwidth than the 1/4 antenna that is on the development kit. You can therefore expect a bit worse performance compared to the DK.

    Do you have a similar product to which you can connect an external antenna to increase the reception range?

    Yes, we have a Front-End Module that does exactly this, the nRF21540 FEM.

    regards
