hi!
I wanted to design a cavity filter.I had drafted the 3D model.(you can see the attachment of the post).First,I needed only design a fixed frequency filter.but later,my boss told me I must think more for redesigning it as a tunable filter.I planed to use a cavity and set a tunable capacitors matrix as the pole's load capcitances.I drew the cavity model and simulated it.but I couldn't get a good tunable performance.I wondered if this style of the coupling cavity didn't fit for the filter.I also have no idea if the capacitors' position at the capacitor matrix would influence the performance.I wonder if you can give me some suggestions.TKS.
