ABSTRACT:
A phase shifter comprises a transmission line having a second terminated transmission line extending therefrom. A single diode is coupled across the second transmission line. The diode is switched between two operating states which changes the effective electrical length of the second transmission line and introduces a phase shift to a signal propagating in the first transmission line.
