Microstripe balun designing

Hi, folks !

Could you tell me the options and guidelines to do a balun with microstripes ? I would like to design a balun to connect a 2.4GHz differencial output of 100-175j to a 50 ohms antenna by means of microstripes.

Any help, suggestion and examples will be so much appreciated.

This is usually done with an LC bridge circuit. AppCAD, which is a free download from Agilent, will be able to calculate the values. Do a web search for the program name.
