Abstract
A multilayered balun transformer in which not only loss can be suppressed but also phase difference or level difference between balanced signal terminals can be suppressed and which become easy to design. In the multilayered balun signal transformer, a coil 4 and a capacitor C1 are formed in a dielectric by a multilayered structure to thereby form a high-pass filter 6. A low-pass filter 9 is formed from another combination of a coil 7 and a capacitor C2. The high-pass filter 6 and the low-pass filter 9 are arranged lengthwise in the direction of multilayer so that the capacitors C1 and C2 are present on extensions of magnetic flux generated in the inside of the coils 4 and 7 respectively.
