Title:
BALUN TRANSFORMER
Document Type and Number:
Japanese Patent JP2022169879
Kind Code:
A
Abstract:
To provide a balun transformer with enhanced magnetic coupling between primary and secondary windings.SOLUTION: A balun transformer 1 includes terminal electrodes E1 to E4, coil patterns 10 and 30 connected in parallel between the terminal electrode E1 and the terminal electrode E2, and coil patterns 20 and 40 connected in parallel between the terminal electrode E3 and the terminal electrode E4. The coil patterns 10, 20, 30, and 40 are coaxially laminated in this order. In this way, the coil patterns 10 and 30 forming the primary winding and connected in parallel with each other and the coil patterns 20 and 40 forming the secondary winding and connected in parallel with each other are alternately laminated. Therefore, it is possible to enhance the magnetic coupling between the primary winding and the secondary winding.SELECTED DRAWING: Figure 5
