i want to design a bandpass filter at millimeter band. what software is better?
can some one design it for me?
substrate: quartz, er=3.78, tanD=0.001
Fo= 35GHz, BW=1GHz.
rejection is -30dB at 34 and 35GHz.
 

ADS, MWOffice, Eagleware-Genesys, Ansoft-Serenade, etc, will do this job. For this particularly application probably the most user friendly is MWOffice or Eagleware.
For some of them you can download a trial version or a student version.

Zeland's FilterSyn is another powerfull tool. synthesis is based on genetic optimization, and results is with 1E3D IE MoM core, one of the best in the market.

+2 cents for ie3d of Zeland , and they provide you now a 60 days trial and manuals after registration.
 

You can try to use HFSS if you'd like to do so.It's one of your best choice.

hi nckwang

ADS momentum is a good EM simulator for doing a mm wave planar filter design ( we have done it & checked with the measured results) ;
MWoffice does not have a great EM simulator as the meshing is not proper ( no triangular meshes are generated and the meshing is done with respect to the grid & not the structure);Also,do not think a 3D EM simualtor like HFSS is required as it would involve a lot of simulation time;
