Multilayer balun transformer

Abstract

Abstract Line elements 24 and 27 are connected in series through a relay terminal 43, to constitute an unbalanced transmission line. Line elements 25 and 28 each constitute a balanced transmission lines. The strip lines 24 and 25 are electromagnetically coupled to constitute a coupler. Similarly, the line elements 27 and 28 are electromagnetically coupled to constitute a coupler. A ground terminal G1 is connected to the balanced transmission lines, which are constituted by the line elements 25 and 28. Meanwhile, A shield terminal G2 is connected to leading portions 30a to 32a of shield electrodes 30 to 32. These two terminals G1 and G2 are electrically independent of each other. <IMAGE>
