Hello all,
I am having a problem of frequency shift in ADS. I have a microstrip filter design which I simulate in Momentum. This filter's center frequency in 1580MHz in ADS 2009U1. However, the same filter's center frequency is 1615MHz in ADS 2011. I use same substrate parameters and mesh settings in both versions. Everything is same except the center frequency. Whatever structure I simulate there is always a 30-40MHz shift between two software versions. Now I don't know which one is giving the correct result. Has anyone noticed a similar problem? What could be the problem? Thank you
