    Looking for tutorials on how to use PMLs in HFSS 9.1

    PMLs in HFSS 9.1 I up load files are basic using of ansoft Hfss 9. Someone maybe need it. You can easily to learn how to use Hfss 9. The files are movie.

    Problem with BPF design values after using ADS

    BPF design Why do you want to use @ds to design BPF? It is hard to use. Use Ansoft designer or other "simple" softwave , pls.

    how to simulate these result?

    It is a good paper. You can find an example in sonnet lite. It is called as "resonator.son".

    Whats the maximum number of meshcells you have simulated in?

    Less than 1000 I have not enough time to simulate circuit, and I think it is unvalued for simulating to a high precision

    Help me design an 8-outports divider using Serenade 8.71

    about divider You used a wrong simulation softwave. You should use one of EM simulation softwave , such as sonnet, IE3d et..

    In need of planar EM simulation manual for Ansoft Designer 2

    Ansoft designer 2.0 I have one. Enjoy it!

    Why do we take characteristic impedance to be 50 ohm ?

    characteristic impedance Agree with Pimr. 20-50 ohm characteristic impedance are still used in some radar system. Because it can get the best performance and easy to connect. Added after 5 minutes: In practical engineering, co-ax cables are not equal 50 ohm usually. They are more or less...

    Which RF simulator is Better ! ! !

    Ansoft is the best. I have solved many problems in practical design.

    Problem on using sonn*t 8.5

    You need newer version of sonnet, or a higher class license.

    It is maybe impossible!

    Problem with thickness/sub height ratio error in Designer

    Designer Conductor Thickness is 125 mils? I think it is wrong. Normally, Conductor thickness is 0.675mil or 1.35mil.
