Abstract
A digital phase shifter includes a plurality of digital phase shift circuit groups in which a plurality of digital phase shift circuits are connected in cascade, one or more relay digital phase shift circuits (digital phase shift circuits) provided between two digital phase shift circuit groups, and two or more bend-type connection units configured to connect one of the two digital phase shift circuit group and the relay digital phase shift circuit and connect the other of the two digital phase shift circuit groups and the relay digital phase shift circuit. At least one of the digital phase shift circuits constituting at least one digital phase shift circuit group and the relay digital phase shift circuit is a mitigation circuit that mitigates the distribution of phase shift amounts.
