磁电双可调滤波器研究进展

Research Progress of Magnetoelectric Double Tunable Filter

随着现代无线通信系统的快速发展和军事信息技术的日益进步,频谱资源越发紧张,这种发展对滤波器提出了更高的要求。滤波器作为无线通信系统中的重要设备,不管是在频率的拆分重组,降低电路串扰以及阻抗匹配等等都与滤波器息息相关,其性能影响着整个通信系统的性能。传统滤波器在无线通信系统中的局限也慢慢开始显现出来,磁电双可调滤波器因为其调节范围大、速度快、能耗小、体积小,在未来的发展中具有很大前景。文章结合近几年磁电双可调微波器件的相关研究成果,汲取他人经验,综述了国内外磁电双可调滤波器研究现状。首先介绍了磁可调以及磁电双可调滤波器基本现状,随后总结磁电双可调滤波器的小型化和全可调的实现方法以及存在不足,最后对未来进行展望。

With the rapid development of modern wireless communication system and the increasing progress of military information technology,spectrum resources are becoming increasingly scarce.As an important equipment in the wireless communication system,the filter is closely related to the frequency separation and recombination,circuit crosstalk reduction and impedance matching,and its performance affects the performance of the whole commu-nication system.The limitation of the traditional filter in the wireless communication system began to appear gradually.Because of its large adjustment range,fast speed,small energy consumption and small size,the magneto electric dual adjustable filter has a great prospect in the future development.In this paper,based on the research results of magnetoelectric dual adjustable microwave devices in recent years and the experience of others,the research status of magnetoelectric dual adjustable microwave filters at home and abroad is reviewed.Firstly,the basic status quo of magnetic adjustable and magnetoelectric double adjustable filters is introduced,then the min-iaturization and fully adjustable realization methods of magnetoelectric double adjustable filters are summarized,and the shortcomings are also discussed.Finally,the future is prospected.
