ADS momentum problem with shifted response

录入:edatop.com    点击:
i designed a hairpin filter with center frequency of 2.14 GHZ and bandwidth 60 MHZ
the circuit simulation gave the correct results making the momentum simulation the response was shifted upwards to 2.24 GHZ i don't know why

how can i solve this problem ?

change the mesh density

Generally speaking, you will very rarely get a direct translation of a result in Circuit simulation in an EM simulation.
You might have to tweak the EM thing a little bit, like reducing, length, width to get it at the exact point you need..

always the circuit models ,will give a shift , coz it is approximate models , but momentum more accurate ,which include the coupling between lines and so on

so u need to optimize the lines in momentum

khouly

Also, like psmon suggested, you could try playing with the mesh density to see if it makes a difference..

Dear all i want to thank everyone answered you were really helpful :D
the solution was combination from replanning the mesh and post optimization
