Circuit for converting from double ended of the gilbert mixer output to single ended

Can any one help me to find a circuit that made conversion from double ended of the gilbert mixer output to single one.

One solution is to use balun but in my case (IC design) I would like to find a passive circuit to do conversion

Thinks

is ur IF signal is ow frequcny u can use active balune , like OTA or something like this

khouly

u can connect two capacitor in series and take the output frm the centre. Like the tapped one. Find the image attached.

Download appcad, there is a section on simple balun design.
