PLANE BALUN BUILT IN PRINTED BOARD AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a plane balun built in a printed board wherein a board can be easily assembled without multilayering and degrading performance. SOLUTION: A transmission line (1) for balance signal and a transmission line (2) for unbalance signal are formed on the same plane so that their side faces are opposite to each other, and a dielectric (3) is interposed between the transmission lines (1) and (2) and between the transmission lines and a ground potential layer (4) nearly parallel to the transmission lines at a prescribed space.
