50 Ohm symetric to asymetric microstrip adapter?

[aNdreiBuuu]

I have to convert 50 Ohm symetryc from an antenna to 50 ohm asymetric in 2.4GHz band. Have anyone some microstripe couplers/adapters models? (dxf)

THX in advance,

I would consider a Marchand balun structure. Seaarch the web - lots of stuff on it.

Try Google. Either "Marchand balun" (as above) or "microwave balun" will give you tons of links. For "Marchand balun" I have got 124 links and the other more general one gave about a thousand.

Go with a lumped element transformer, like ESLT-S245E:
