I can't understand how S11 can be constant, while S21 changes (in software simulation).
For example, same filter with small adjustment in configuration:
configuration1: S21=-2.5dB, S11=-11dB
configuration2: S21=-2.5dB, S11=-17dB
If i use real measurements with network analyzer, would it be similar? Where that 17dB-11dB=6dB comes from if S21 is almost constant?
