When I open the example of rectifier from ADS2009, I can not get the output voltage as half wave of sine. How could I get this?

---------- Post added at 10:06 ---------- Previous post was at 09:32 ----------

I supply sufficient AC voltage but output voltage is again full wave. What should I do?

I have done it many times . Output voltage is always the same like input.

Here I share the picture of simple circuit and input-output voltage . what should I do to get half wave sine?

Remove 50 Ohm resistor before the diode and see what happens.

20 GHZ !!!
the cap of the diode is making a problem, your diode id not conducting (increase to 5v ac pp )and at that freq u have all kinds of matching problems .
first reduce the load to 50 ohms, next try putting the diode in parallel after the 50 ohm and u will have half wave shorted at that's what made usually in hi freq. your scope should be in dc mode...
is that a model or real circuit ? reduce freq to 1Mhz and post the result.
sdd_diode why cant i find it in internet send data or link.

Hi,
Try to work at Transient not at AC.
