Definition of balun in English:



  • A type of electrical transformer used to connect an unbalanced circuit to a balanced one.

    • ‘In a simple dipole, the balun assures that the dipole, and not the feed line, is doing the radiating!’
    • ‘All baluns, even transmission line baluns, will have significant flux in the core with real-world loads.’
    • ‘They weigh less than most current baluns and coax coils, and they are less bulky.’
    • ‘Also included are three lengths of shrink tubing to enclose the balun and hold it in place on the cable.’
    • ‘You may have received these little baluns packaged with appliances in the past.’
