Title:
DIGITAL PHASE SHIFTER
Document Type and Number:
WIPO Patent Application WO/2024/047891
Kind Code:
A1
Abstract:
A digital phase shifter according to the present invention is provided with: a first column; a second column extending parallel to the first column; and a connection section that electrically connects one end of the first column and one end of the second column. Each of the first column and the second column is formed by cascade-connecting a plurality of digital phase-shift circuits provided with outer lines, etc. Regarding the digital phase-shift circuits adjacent to each other in each of the first column and the second column, the outer lines adjacent to each other are separated, a first ground conductor and a second ground conductor adjacent to each other are separated, and the outer lines have opposite positional relationships with signal lines. The plurality of outer lines possessed by the first column and the plurality of outer lines possessed by the second column are not adjacent to each other.
