Hello everyone,
My question is detailed one i hope to get some valuable response.
I have designed a bandpass filter and want to see its response on 4 multilayer stackup (Top, gnd, pwr, bot) on ADS 2014.
I have few issues that i want to clear.
1) I simulated BPF alone and its response is correct when there is complete ground plane. (signal, dielectric, gnd)
2) When i changed the ground plane of BPF to aligned it with top layer of multilayer stackup its results are changed. Can anyone tell me how i can achieve correct results as i get it with complete ground plane beneath.?
3) I aligned my BPF (sig, dielectric, gnd) with 4 layer stackup (top, gnd, pwr, bot) and simulated the whole and its results were again changed from previous one.
I have attached substrate description aswell.
