I designed a simple 90 degree branchline coupler in ADS, tuned it to my liking (my values were very close to theoretical). Now, I simulate the structure in Momentum and my curves are all off, I get 3 dB less since it got shifted by several GHz.
Any suggestion and ideas why might my results be so different (and which one to trust)?
