Abstract :
A Ku-band microstrip phase shifter capable of continuous phase and amplitude control is described. Three dual-gate FET amplifiers provide variable amplitude vectors that are separated by 120/spl deg/ and summed through an arrangement of quadrature couplers. The described phase shifter provides a full 360/spl deg/ shift with an amplitude weighting capability of more than 20 dB.
