The design of X-band drop-in microstrip ferrite circulator based on PCB technology

In this paper,a design idea of drop-in microstrip ferrite circulator based on PCB technology is proposed.According to design theory of the corresponding junction circulator,a drop-in X-band double-junction microstrip circulator based on PCB technology is designed.Simulation optimization is carried out by electromagnetic simulation software.The test results of the sample show that,the circulator has a good circulation performance between 8 and 12 GHz,with a VSWR of less than 1.4,single-junction isolation of more than 17 dB,single-junction insertion loss of less than 0.5 dB,double-junction isolation of more than 28 dB,and double-junction insertion loss of less than 1.2 dB.The feasibility of the design idea for drop-in microstrip circulator is proved.With the increasing integration of the system,the design has great potential for application.
