Abstract
A distributed combiner/splitter having a first line formed of a first planar winding in a first conductive level and of a second planar winding in a second conductive level, and a second line formed of a third planar winding interdigited with the first winding in the first level, and of a fourth planar winding interdigited with the second winding in the second level, the windings having an increasing width from the outside to the inside.
Claims18
A distributed combiner/splitter comprising:
- a first line formed of a first planar winding in a first conductive level and of a second planar winding in a second conductive level;
- and
- a second line formed of a third planar winding interdigited with the first winding in the first level, and of a fourth planar winding interdigited with the second winding in the second level, said windings having an increasing width from the outside to the inside.
A method for manufacturing a combiner/splitter with two coupled lines, wherein the lines are made in the form of planar conductive windings of increasing width from the outside to the inside in two levels stacked up on each other, each of said lines comprising one of said windings in each of said levels and the two windings of a same plane being interdigited with each other.
An electrical power combiner/splitter with distributed lines, comprising:
- a first line including a first planar winding in a first conductive level and a second planar winding in a second conductive level;
- and
- a second line including a third planar winding interdigitated with the first planar winding in the first conductive level and a fourth planar winding interdigitated with the second planar winding in the second conductive level, wherein said windings have an increasing width from outside to inside.
