Abstract :
In this paper the questions related to the choice of variants of digital phase shifters circuits based on the symmetric reactive four-poles with switching elements are considered. The two basic conditions at implementation of which the chosen circuit can be used for realization of phase shifter are formulated. The examples of proposed approach using to different types of circuits are given.
