Document Type and Number:

Japanese Patent JP4586282

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a laminated balance transformer capable of reducing a ground side impedance without increasing the mounting area. SOLUTION: Line parts 24 and 25 are disposed between ground electrodes 31 and 32 and formed in a strip line structure. Line parts 28 and 29 are disposed between ground electrodes 33 and 34, and formed in a strip line structure. The lines parts 24 and 28 are connected in series via a trunk terminal or the like, to constitute an unbalanced transmission line. The line parts 25 and 29, respectively constitute balanced transmission lines. The parts 24 and 25 are electromagnetically coupled to constitute a coupler, Similarly, the parts 28 and 29 are electromagnetically coupled to constitute a coupler. Two ground electrodes 32 and 33 are respectively arranged between the parts 24 and 25 and between the parts 28 and 29.
