Laminated balun transformer |
摘要 |
A laminated balun transformer includes a dielectric sheet for which a lead electrode is provided at its surface, dielectric sheets for which lambd/4 striplines are provided at their surfaces respectively, and dielectric sheets for which ground electrodes are provided at their surfaces respectively. One pair of opposing striplines is provided with a dielectric sheet disposed therebetween so as to be electromagnetically coupled. The other pair of opposing striplines is provided with a dielectric sheet disposed therebetween so as to be electromagnetically coupled. An end of a stripline of one pair of striplines is electrically connected to an end of a stripline of the other pair of striplines through an external electrode.
