A phase shifter is a kind of functional device used to regulate the phase of guiding wave output signal, and is widely used in beam formation network, phase modulator, phased array antenna and other electronic, radar and communication systems, and has the most direct impact on the performance of related systems. Therefore, it is very important to design a practical microwave phase shifter with high performance, stability, miniaturization and low cost to meet the future development needs. In order to solve the bottleneck of current technology development and realize relevant technical innovation, it is necessary to comprehensively analyze the technical overview, advantages and disadvantages and development status of various phase shifters, accurately sort out the future development trend of phase shifters, and better integrate the latest academic research progress in related fields into the design of phase shifters. Based on the goal mentioned above, the development of phase shifter, the ferrite phase shifter, PIN diode phase shifter, MEMS phase shifter, ferroelectric phase shift principle and performance index of the phase shifter are analyzed separately in systematic summary based on BST ferroelectric material phase shifter microwave circuit design, and combined with the related technical trend, some prospects for the development of BST ferroelectric phase shifter are made to a certain extent.
