Piezo phase shifter is a phase shifting device based on the principle of piezoelectric effect, with built-in high-performance piezo ceramics, which can realize the phase shifting function by applying voltage to piezo ceramics to generate micro-motion. Due to the high precision and fast response speed of piezo ceramics, nanoscale stepping motion and millisecond fast response can be generated to achieve high-precision and fast phase shifting. It can carry out phase modulation more accurately, and is widely used in many fields such as optics, communication, and medical treatment.
