Abstract : Investigations continued on microwave phaseshifting techniques, other than ferromagnetic and mechanical methods, to provide improved electrical scanning, and to develop models of a phase shifter. A method was investigated for obtaining continuous phase shifts using identical diodes placed in bias opposition at the outputs of a 3-db hybrid coupler. This technique was expected to yield a phase shift characteristic which was less dependent upon the RF power level. Results were obtained which were essentially in agreement with theory, and the advantages and disadvantages of this technique are discussed. (Author)
