nrf52840 rssi filter

[Yahel_Wiliot]

I have read that there is a used to measure the RSSI values such that it will measure only the RSSI values of a 2.4GHz signals. However, I can't find this filter specification. Mainly I'm interested to know how the measured RSSI value of the signal would be attenuated if its frequency is shifted.
would appreciate a link to relevant documentation or specification of the discussed filter.

Hello,

We don't provide more information than specific in the radio chapter:

I suggest if you want to test or chacterize it further you can always download nRF Connect for desktop and run the RSSI app:

If you connect an nRF52840-DK to the PC you can measure the RSSI value radiated or conducted by setting up the DK as described here:
