L Band Phase Shifting Techniques

A discussion of techniques applicable to obtain digital phase shift without continuously-applied current is gice $2.60 Hughes Aircraft Co., Culver City, Calif. L-BAND PHASE-SHIFTING TECHNIQUES. Final engineering rept., 1 July 61-16 Mar 62. 16 Mar 62, 15p. incl. illus. table, 2 refs. (Contract NObsr-81378, Proj. SR-0080302) Unclassified report DESCRIPTORS: *Phase shifters, Digital systems, Ferrites, Magnetic fields, Measurement, L band. A discussion of techniques applicable to obtain digital phase shift without continuously-applied current is given. Also, a phase shifter developed during the program to which the digital techniques are applicable is described. The construction and method of operation of a prototype digital phase shifter is described and the performance is given. Work was performed to determine the cause of variation of insertion loss between the prototype phase shifters. (Author).
