I am using RF Blockset to simulate the distortion characteristics of an RF amplifier and want to calculate the input power relative to the third order intercept point needed to maintain distortion below a certain amount.
Given a third order intercept point, this is relatively simple to calculate manually if just considering two tones, however RF Blockset allows one to simulate with multiple arbitrary tones and I am using it with a 64QAM input.
What is the reference impedance?
