Hi all,
I have designed an X band interdigital bpf on ADS Momentum and implemented it. On implementation I have a ripple problem like about 1 dB that I don't see on simulation. I have simulated exactly the same geometry that I have put on pcb but there are no ripples on simulation. What do you think I am missing on simulation? I am adding tangent loss, copper thickness, conductivity etc. What can cause these ripples?
Thank you in advance
