More Information
Summary:A laminated balun transformer includes first line elements which are connected in series through a relay terminal, to constitute an unbalanced transmission line. Other line elements each constitute a balanced transmission lines. Strip lines are electromagnetically coupled to constitute a coupler. Similarly, other line elements are electromagnetically coupled to constitute a coupler. A ground terminal is connected to the balanced transmission lines, which are constituted by a pair of the line elements. Meanwhile, a shield terminal is connected to leading portions of shield electrodes. These two terminals are electrically independent of each other.
