Abstract
An inductor structure includes a first quadrupole inductor, and a second quadrupole inductor, wherein the second quadrupole inductor overlaps the first quadrupole inductor. In certain aspects, the inductor structure may be included in a filter, which may also include one or more capacitors coupled to the inductor structure.
Claims30
An apparatus, comprising:
- an inductor structure, wherein the inductor structure includes:
- a first quadrupole inductor;
- and
- a second quadrupole inductor, wherein:
- the second quadrupole inductor overlaps the first quadrupole inductor, and
- each of the first quadrupole inductor and the second quadrupole inductor respectively comprises four inductors in which current is configured to flow in a clockwise direction in two of the four inductors and current is configured to flow in a counterclockwise direction in the other two of the four inductors.

A frequency multiplexer, comprising:
- a first filter coupled between a common port and a first port, wherein the first filter comprises:
- an inductor structure having a first terminal and a second terminal, the inductor structure comprising a conductor path between the first terminal and the second terminal, wherein the conductor path includes:
- a first quadrupole inductor;
- and
- a second quadrupole inductor, wherein:
- the second quadrupole inductor overlaps the first quadrupole inductor, and
- each of the first quadrupole inductor and the second quadrupole inductor respectively includes four inductors in which current is configured to flow in a clockwise direction in two of the four inductors and current is configured to flow in a counterclockwise direction in the other two of the four inductors;
- and
- a second filter coupled between the common port and a second port.
6 more elements
An apparatus, comprising:
- an inductor structure, wherein the inductor structure includes:
- a first dipole inductor;
- and
- a second dipole inductor, wherein;
- the second dipole inductor overlaps the first dipole inductor, and
- each of the first dipole inductor and the second dipole inductor respectively comprises two inductors configured to have opposite magnetic field polarities due to opposite current flows in the two inductors.
