I want to design flat magnitude response IIR filter to simulate the memory effect of High Power Amplifier nonlinearities

I am not certain what you want the filter to do. One option is to design a lowpass filter with a cutoff near the Nyquist frequency. There are several ways to implement such a filter, and filter your signal.

It would help if you describe ‘the memory effect of High Power Amplifier nonlinearities’ in more detail. I am familiar with AF and RF power amplifiers, however I am not aware of this effect.

Unfortunately, I cannot help you with this. I have not used Simulink in a while, and I cannot design filters with it.

From your initial description, I thought that this was a much more straightforward problem than it turned out to be.

when I tried to use the given parameters to simulate the filter response, I get a different response? can you help me to estimate the parameters that give the original response ?
