  1. ANALOG AND DIGITAL PHASE SHIFTERS

  2. Center frequency of operation • Bandwidth • Insertion loss (for 360° phase shift) • VSWR or return loss • Switching time (for digital operation) or time required for 360° phase change (for analog operation) • Switching power or energy (for digital operation) or dc holding power (for analog operation) • Phase error • Power-handling capability(peak and average) PARAMETERS OF AN ELECTRONIC PHASE SHIFTER

  3. They are broadly divided into: • Ferrite Phase Shifters • Semiconductor Phase Shifters CLASSIFICATION OF DIGITAL PHASE SHIFTERS
