BALUN design steps in ANSOFT HFSS

Hi all,

I want to design a single ended to differential signal converter balun which is to be used in cascading LNA & MIXER.
i tried in asitic but the parameters extracted are not correct.

I am new to HFSS
Do anyone have a tutorial of balun simulation in HFSS.
please post the link or any ideas will help.
Thank You.

It is easy to make the structure but how to do its analysis & parasitic extraction?

plz reply

thank u in advance..............
