Hi,
I tried with both types of ports, single and differential ports, but the results are almost the same. I found an interesting example in this paper ( **broken link removed** ) where there are model results, measurements and simulation, so a good way to validate my model and simul. The problem is that i get a resonant frequency at 28 MHz instead of 53 MHz, I tried to do different types of simulation but nothing changes...can you suggest me something? thank you very much..
