POWER DIVIDER AND POWER COMBINER

摘要

A power circuit suitable for combining or splitting broadband signals. The circuit includes a stepped impedance section, a core section and a first, second and third port. The stepped impedance section and the core section are interconnected at an interconnection. The stepped impedance section includes a first transmission line running from the first port to the interconnection. The core section includes a second and a third transmission line running from the interconnection to the second and third ports, respectively. The second and third transmission lines each have at least a first and a second core subsection. The number of core subsections of the second transmission line and the number of core subsections of the third transmission line is equal, to the number of stepped impedance subsections of the stepped impedance section.
