nRF52840 3rd and 2nd Harmonic Spec - Clarification

The 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?

I am doing my testing using the Nordic DTM with carrier only (no modulation) and we are in the process of using the recommended LPF for power levels ≥ 5dBm.

Thanks,

Ted

It somewhat depends on the design but with the reference design, you should be able to see these levels for the harmonics in 8 dBm mode. Provided you are using the 4 component matching network, config #7 https://infocenter.nordicsemi.com/topic/ps_nrf52840/ref_circuitry.html#unique_305604804
