I have a need for designing some narrowband bandpass parallel coupled line filters on alumina. Last time I did this, I optimized them in Eagleware Genesys, and then simulated them in HFSS for a final tweak. They came out without the need to respin them.
I no longer have HFSS available. Rather than just buy or lease HFSS, is there a better filter simulation program out there now? Due to the schedule constraints, I do need to hit these right the first time. It is not good enough if they program is 3% off in frequency, for instance.
