Abstract
The disclosure describes a multi-section directional coupler comprising: a plurality of conductive lines, each conductive line comprises a plurality of line sections; a plurality of coupled line sections, each coupled line section comprises a first line section of a first conductive line and a second line section of a second conductive line, the coupled line sections comprise different coupling strength values, the coupled line sections facilitate signal coupling; and at least one grounded conductive coupling reduction structure arranged adjacent to a selected coupled line section and operable to reduce a coupling value between a respective line section of the first conductive line and a respective line section of the second conductive line of the selected coupled line section. The selected coupled line section comprises a smaller coupling strength value than another one of the coupled line sections. Methods of manufacturing and operating the multi-section directional coupler are also provided.
