YIG调谐带阻滤波器的新应用

New Applications of YIG-tuned Band-reject Filters

首先介绍了YIG调谐滤波器的工作原理、特点和常规应用。在此基础上创造性地提出了YIG调谐带阻滤波器的新型用法,包括梳谱式阻带可变滤波器、多路幅相一致带阻滤波器以及开关滤波器,不仅拓展了YIG调谐滤波器的功能,而且改善了YIG器件扫速等固有的缺陷,为YIG调谐带阻滤波器更为广泛的应用找到了新的思路和方向。

This paper firstly introduced the principle, characteristics and conventional applications of YIG-tuned band-reject filter. Then new applications including comb band-reject adjustable filter, multi-channel amplitude/phase consistent band-reject filter and switch filter were put forward not only to expand the function of YIG-tuned filters, but also to mend the fixed limitation of YIG-tuned component and to find new thought or direction for wider applications of YIG band-reject filter.
