Abstract: In this paper,the HFSS software is used as a platform to simulate the protective layer of the X-band LTCC ferrite circulator.The general rule of the characteristics is obtained,and the selected substrate material and thickness are determined.Based on the simulation and analysis of the defects caused by the current process level,the solution was found,which provideda theoretical basis for the preparation and use of the circulator,and improved the application efficiency of the circulator in the microwave transceiver system.
