X波段高隔离度功分器设计

Design of Power Divider with X-band High Isolation Degree

在微波射频电路中,为实现对信号的等功率或不等功率分配,常常需要功分器来完成。本文利用HFSS仿真设计了8.3GHz点频具有一定带宽的功率等分功分器,其中考虑到功分器中的一个特别重要的指标——隔离度,通过相关设计提高该指标,改善功分器的性能,从而达到需要的设计要求,并对加工实物进行测试与仿真结果吻合满足设计要求。

In the microwave radio-frequency circuit,the power divider is often needed to redistribute the signals with or without equal power.In this article,a power divider with a certain bandwidth and equal power is designed in 8.3 GHz point frequency using HFSS simulation.An important index of the power divider,isolation degree,is considered.This index is improved through relevant design to improve the performance of the power divider,so as to achieve the required design requirements.The real object is processed for testing,and the simulation results are consistent with the design requirements.
