Loadpull simulation is based on the harmonic simulation, which is a large signal simulation.
I match input , output and interstage impedance of PA from the loadup simulation, and then run the HB1TonePAE simulation( Harmonic simulation) , which gives me the input/output return loss at certain given input signal, for example, 0dBm, 10dBm.
Then I run PA for ac simulation, which is a small signal simulation, why the input and output return loss( S11, S22) is quite different from that of HB1TonePAE simulation( Harmonic simulation)? Why?
Thanks,
