    Is there some estimation about how much to back off output power when amplifying a multi-carrier signal? Asking for a friend...

    I'd assume that you want to back off about as much as the Peak to Average of the signal, so you need to know that first.

    Yes, the general recommendation is to back off the output power by approximately 6–10 dB to avoid intermodulation distortion when amplifying a multi-carrier signal. The exact value depends on the amplifier's linearity and the number of carriers.
