A balun is a type of transformer: it's used to convert an unbalanced signal to a balanced one or vice versa. Baluns isolate a transmission line and provide a balanced output. Quite often toroids are used to make baluns with. Even a ferrite rod from an old AM radio can be used. I however have something against using ferrite materials in baluns.

A balun can take many forms and may include devices that also transform impedances but need not do so. Transformer baluns can also be used to connect lines of differing impedance.
