https://test-devzone.nordicsemi.com/f/nordic-q-a/88810/nrf52840-3rd-and-2nd-harmonic-spec---clarificationThe spec for the nRF52840 indicates a maximum power level of 8.0 dBm and -51dBm for 2nd order harmonics and -48dBm for 3rd order harmonics. What is the output power level for the harmonic specifications?
