I drew rectangles where the lumped component is supposed to connect one metal to another. I assigned the rectangles with the lumped RLC boundary condition. I got the resonant frequency of my device with lumped components. I wanted to export the whole setup to ADS. So, I replaced the lumped RLC boundary condition with lumped ports excitation. I simulated the same structure simply by replacing the lumped RLCs with lumped ports. The snp file of the device was exported to ADS. I replaced the lumped ports with actual lumped components on ADS. I used the same values for the lumped components as in the lumped RLCs. However, I see a significant variation in the resonant frequency of the device when simulated on ADS. It shifts from 2 GHz to 2.5 GHz.&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>Has anyone experienced similar problems? Any tips will be appreciated.
