Hello,
I am interested in the relative levels of the harmonic products in an RF power amp. My understanding is that the fundamental signal applied will increase linearly (in a non-saturated amp). Is this also true of the 2nd harmonic (assuming a wide band amplifier)? I know the two-tone intermods have 2/3 dB increase for each dB of tone increase, but I am just speaking of the actual harmonic distortion of the amp itself.
TIA
"two-tone intermods have 2/3 dB increase for each dB of tone increase"
I think this is wrong ,It should be that
two-tone intermods will have 2dB increase
for each dB of tone increase.
Is it right ?
Thanks. I probably should have left out the two-tone info, because what I'm really concerned about is the amp 2nd harmonic. If I put in a 1GHz signal there is a signal also at 2GHz from the amplifier distortion. If I then increase the 1GHz signal 10dB (assuming no saturation), will the 2GHz signal increase 10dB as well?
