output power variation over channel

[rico]

I measured the output power over all the channel, see graphics below. It is not much, but i still would like to know why the output power drifts over frequency. Is this by design or is it maybe from the measurement it self.

I measured with a nRF52840 DK and an muRata SWF adapter.

Hi, 

the deviation is less then 1 dBm, and an drift +/- 1 dBm is as expected.
