Hello, i have i rectifier with serie diode as shown in figure, i calculate Zin=2.5+j*75.48 , when i match it on 50 Ohm i got this result : S11= -0.7 and real Zin not near 50 Ohm ..... any one can tell me where is the problem ?

hello, you have to add the librairie « High-Frequency Diode" to your workspace before you build the schematic.

Yes this i know.
I mean model with s-parametres, or its a non-linear model provided by Vendor site?
Maybe u take this model on modelithics site?
