High power wideband balun and power combiner/divider incorporating such a balun

摘要

A balun transformer includes a coaxial transmission line terminating at one end with balanced terminals and terminating at another end with unbalanced terminals. At least two impedance segments are connected in series between the balanced terminals and the unbalanced terminals, each of the at least two impedance segments being formed by a magnetic core and at least one winding of the coaxial transmission line wound about the magnetic core.
