I am designing a 90 degree hybrid in 29-31 GHz. While I could get a decent result with the hybrid itself using momentum, the result would just be way off once I simply introduce extented 50 Ohm transmission lines to the ports. The same thing happened to me in the 13.5 - 15 GHz previously. Anybody had such experience?

It seems not right to me. I can not afford to simulate the whole structure with every small changes like this. Please help!
