Document Type and Number:

WIPO Patent Application WO/2005/117201

Kind Code:

A1

Abstract:

A laminated balun transformer including a laminate (10a) having laminated ceramic dielectric layers (11 to 12). The laminate (10a) is provided with an unbalancing signal terminal (P₁), a grounding terminal (G₁), a balancing signal terminal (P₂), a balancing signal terminal (P₃), a grounding terminal (G₂) and a dummy terminal (P₄). The dielectric layers (13, 15 and 16) are provided with a first line (13a), a second line (15a) and a third line (16a), which have a sufficiently shorter line length than the quarter wavelength of an input signal wave. The second line (15a) is electromagnetically coupled across the dielectric layers (13 and 14) to the first line (13a) and across the dielectric layer (15) to the third line (16a).
