Hi,

I would like to have an amplifier, which is frequency selective and has P1dB, IP3 ... as a replacement of an active low pass filter based on an operational amplifier. I want to use this block in HB-simulations in which I cannot use the original Spice model.

My idea: Simulating the transfer function in an AC simulation and use this data file in the filebased S21 field of the Amplifier2 block.

Is that the best way. Do you have an example?

Please let me know. Wolfram

There are 7 differen ways to specify the nonlinearities (GCOMP1-GCOMP7). Uncomment one of these blocks and specify your parameters.

S11 = file{DAC1,"S[1,1]"}

S21 = file{DAC1,"S[2,1]"}

S12 = file{DAC1,"S[1,2]"}

S22 = file{DAC1,"S[2,2]"}

The nonlinear parameters can then be set in the Amplifier2 component. This kind of emulates the AmplifierS2D component...
