Abstract
A digital phase shifter includes a first row, a second row arranged to extend in parallel to the first row, and a connection unit electrically connecting one ends of the first and second rows. Each of the first and second rows is configured by connecting a plurality of digital phase shift circuits in cascade, and each digital phase shift circuit includes an outer line and the like. For the digital phase shift circuits adjacent to each other in each of the first and second rows, outer lines adjacent to each other are separated, a first ground conductor and a second ground conductor adjacent to each other are separated, and positional relationships of the outer line to a signal line are reversed. A plurality of the outer lines included in the first row are not adjacent to a plurality of the outer lines included in the second row.
