- generator with an output impedance of 50 ohms
- chip with an input impedance of 1000 ohms (at 100 MHz)
- microstrip line on PCB, and its S-parameters in ***.S2D file
why? simulation in ADS gives mag(S21) = 0.424 (and not seek to 1)
for example, harmonic balance and transient analysis give results, in which no reflections...
You could try to simulate the S parameter over a frequency sweep. It would be easier when the S parameter is shown over a frequency sweep.
In the first figure, there are no start and stop frequencys set.

I want understand how to calculate V2 on TERM2(Z2=1000 ohms) if S21 = 0.425 ?
for example, HB and transient analysis give results, in which NO reflections(HB_TR_sim2.jpgHB_TR_sim_res2.jpgsee above)
and V2 = 0.952 -> This is understandable and it's true.. (1*[1000/1050]=0.952)
