Abstract
The invention discloses a phase shifter. The phase shifter is a novel circuit structure which realizes a phase shifting function by adopting a composite right and left handed transmission line unit structure. The phase shifter comprises an input stage amplifier, one or multiple composite right and left handed transmission line unit structures, and an output stage amplifier. The input stage amplifier matches an impedance at an input end with an impedance of each composite right and left handed transmission line unit structure and amplifies an signal; each right and left handed transmission line unit structure plays a role of signal phase shifting; and the output stage amplifier matches the impedance at the output end with the impedance of each composite right and left handed transmission line unit structure and amplifies the signal.
