How do simulate the RF input matching on PCB correctly?

[Alvin_Hu]

Hello all, I am glad you read this topic. And I will appreciate if you give me any suggestion.

I was wondering how to simulate the RF input matching correctily if you want to do
a good RF input matching on PCB. I simulate some matching circuit but I found the simulated circuit had bad performance on PCB. Is it because I don't have correct passive component model? Or fringing effect? Thanks everyone.

You can add PCB effect into the simulation. If you use ADS, you can use Momentum to simulate PCB layout and then bring it back into the schematic simulation. here the overview of the operation
