Development of the 0～2π Intelligent Wide Band Phase Shifter

摘要

A digital phase shifter is presented in this paper. It can shift 0 ～2π phase by Microcomputer arbitrarily and lock in phase using phase detector in according to the set accuracy demands automatically and has good characteristics of phase shift in range 0~1MHz. If the phase shifter is used in phase detecting system for X-R orthogonal Decomposition, the accuracy and speed phase shift will be raised greatly and the ratability and automation level of the system also improved.
