Abstract
A balun transformer with a common mode coil is formed by parallel two-strand cable wound around a common core having through-holes through which the cable passes. The common mode coil can be connected either on the input side or the output side of the balun transformer. Because only one core is used to form both the balun transformer and the common mode coil, the outer dimensions of the transformer can be reached, along with manufacturing costs, to reduce the number of man-hours required to manufacture the transformer by this invention. This configuration also permits shorter connections between the balun transformer and the common mode coil.
