Abstract
A phase shift circuit and a phase shifter are achieved which are small in size and wide in bandwidth. The phase shift circuit includes a capacitor, and a series circuit composed of a switching element which exhibits capacitivity when it is in an off-state and an inductor connected in series with this switching element, the series circuit being connected in parallel with the capacitor. The capacitor and one terminal of the series circuit are connected with a high frequency signal input/output terminal, and the other terminal thereof is connected with ground.
