A balun n is an electrical device that converts between a balanced signal (two signals working against each other where ground is irrelevant) and an unbalanced signal (a single signal working against ground or pseudo-ground). A balun can take many forms and may include devices that also transform impedances but need not do so. Transformer baluns c...
a device for transforming an unbalanced voltage to a balanced voltage or vice-versa
A transformer device used for matching balanced and unbalanced circuit elements.
An acronym for BALanced/UNbalanced. A device commonly used to change one cabling media to another (ex. coaxial to twisted pair balun).
Balanced Unbalanced (device)
The word balun comes from its function it connects balanced to unbalanced cables. Most baluns also have the job of correcting any differences in characteristic impedance.
Balun is a shortened term derived from BALanced to UNbalanced transformer. A

This is a transformer used to match or transform an unbalanced coaxial cable to a balanced twisted pair system, or visa versa.
(NETWORK GLOSSARY) Balanced, unbalanced. Device used for matching impedance between a balanced and unbalanced line (usually twisted pair and coaxial cable).
A transformer circuit that couples a balanced transmission line to an unbalanced transmission line. 
Balanced/Unbalanced. A device that links together dissimilar
VGA to Cat 5 Balun (PC side) - MuxLab 500040A device which changes an audio or video signal from unbalanced wiring to balanced (or vice versa). The name is derived from BALanced / UNbalanced.
