A coaxial phase shifter is an electronic device used to adjust the phase of microwave components. It is widely applied in fields such as radar, missile attitude control, accelerators, communications, and instrumentation.
The fundamental principle of a coaxial phase shifter involves utilizing the transmission medium to introduce a phase shift to the propagating wave within it. Both early analog phase shifters and modern digital phase-shifting technologies (achieved using A/D and D/A conversion) possess the function of adjusting the phase of an AC voltage.
Design considerations for coaxial phase shifters include parameters such as insertion loss, Voltage Standing Wave Ratio (VSWR), and RF power. These parameters ensure the device provides effective phase adjustment within a specific frequency range while maintaining low insertion loss and low VSWR.
