ON-CHIP DIFFERENTIAL WILKINSON DIVIDER/COMBINER

摘要

The present disclosure provides for a fabrication layout and design for transmission lines that are implemented as part of a differential Wilkinson power divider/combiner. The transmission lines are configured and arranged in a poly-loop line geometry. The poly-loop line geometry includes overlapping transmission lines to route differential signals within the differential Wilkinson power divider/combiner. The overlapping transmission lines each include a crossover region to route the differential signals. The crossover represents a spacing between the overlapping transmission lines that encompasses a magnetic flux of the overlapping transmission lines.

主权项

1. A differential power divider/combiner, comprising:
a first pair of transmission lines coupled between a differential input and a first differential output, wherein a first transmission line and a second transmission line of the first pair of transmission lines are disposed to form respective first and second open loops that are adjacent to one another between the differential input and the first differential output, and cross over one another in a first crossover region; a second pair of transmission lines coupled between the differential input and a second differential output, wherein a third transmission line and a fourth transmission line of the second pair of transmission lines are disposed to form respective third and fourth open loops that are adjacent to one another between the differential input and the second differential output, and cross over one another in a second crossover region; a first resistor coupled between the first transmission line and the third transmission line; and a second resistor coupled between the second transmission line and the fourth transmission line.
