Kind Code:
A
Abstract:
To provide a balanced-to-unbalanced transformer with an excellent phase characteristic.SOLUTION: A balanced-to-unbalanced transformer A10 comprises: a first inductor L1 and a second inductor L2; a first capacitor C1 and a second capacitor C2; an unbalanced terminal T1; a ground terminal T2; a first balanced terminal T3; and a second balanced terminal T4. Each of the first inductor L1 and the second inductor L2 is arranged in a second direction y. Each of the unbalanced terminal T1 and the ground terminal T2 is arranged in the second direction y. Each of the first balanced terminal T3 and the second balanced terminal T4 is arranged in the second direction y. The first balanced terminal T3 is positioned on one side in a third direction x to the unbalanced terminal T1. The second balanced terminal T4 is positioned on one side in the third direction x to the ground terminal T2. A first center P1 viewed in a first direction z of the first inductor L1 is deviated to the other side in the third direction x from a second center P2 that is viewed in the first direction z of the second inductor L2.SELECTED DRAWING: Figure 4
