hi,

I want to simulate a micro stripe line of a given length in ADS Momentum. As shown in the attached figure , first i attached the 50 ohm port at the edge of the patch and performed simulation. Secondly i placed the port inside the structure not at the edge .Now the simulation result slightly differs from the first one. Which one is correct. What is the difference in calibrated ports and internal ports in ADS.

Thanks for reply.
I have studied "Ports in Momentum" topic available on ADS website. I have also seen momentum examples. But i am still confused about the position/type of ports (internal or at the edge) when it involves any TRANSISTOR (LDMOS) at one side.

Usually, you want to have port calibration enabled, for more accurate results. Port calibration is only possible when the port is on the edge (not inside) the polygon.
For transistor and other components, have a look at the documentation for "SMD" calibration type-
