Balun structure
First Claim
1. A balun structure, comprising:
- a substrate;
a first coil structure having a spiral shape and on the substrate, the first coil structure including;
a first single-layer coil, andat least one first laminated coil connected to the first single-layer coil,wherein the first single-layer coil is surrounded by the at least one first laminated coil; and
a second coil structure having a spiral shape and on the substrate, the second coil structure including;
a second single-layer coil, a projection of the second single-layer coil on a surface of the substrate overlaps a projection of the first single-layer coil on the surface of the substrate, andat least one second laminated coil connected to the second single-layer coil,wherein a number of the at least one second laminated coil is larger than or equal to a number of the at least one first laminated coil, and the at least one second laminated coil is arranged alternately with the at least one first laminated coil or the first single-layer coil in a plane parallel to the surface of the substrate.

Abstract
A balun structure is provided. The balun structure includes a substrate, a first coil structure and a second coil structure having a spiral shape and on the substrate. The first coil structure includes a first single-layer coil surrounding by first laminated coils that are connected to the first single-layer coil. The second coil structure can include a second single-layer coil and second laminated coils that are connected to the second single-layer coil. A projection of the first single-layer coil and a projection of the second single-layer coil on a surface of the substrate overlap with each other. A number of the second laminated coils is larger than or equal to a number of the first laminated coils. The second laminated coils are arranged alternately with the first laminated coils or the first single-layer coil in a plane parallel to the surface of the substrate.
