结合笔者及其课题组多年来的研究成果,集中介绍了近几年出现的多频带通滤波器的设计和实现技术——为得到各通带频率和带宽都可控的多频滤波器,利用多通带谐振器设计双频及三频滤波器；为减小滤波器尺寸,利用阶跃阻抗谐振器设计双频及三频滤波器；为方便控制通带频率,基于枝节线加载谐振器设计双频及三频滤波器；为获得更好的带外特性和更多通带,基于组合谐振器设计三频及四频滤波器.文中最后介绍了基于多枝节加载谐振器的高阶双频滤波器的设计方法.在保持第一通带特性不变的前提下,该高阶双频滤波器的第二通带可以很方便地进行调节.

Based on the research results of the authors and their team,this paper introduces the recently-developed techniques for the design and implementation of multiband bandpass filters,namely,designing dual-and tri-band bandpass filters respectively with multi-passband resonators to obtain independently-controllable passband frequency and bandwidth,with stepped impedance resonators to minimize the filter size,and with stubloaded resonators to obtain conveniently-controllable passband frequency,and,developing tri-and quad-band bandpass filters with assembled resonators to obtain improved stopband rejection characteristic and more passbands.Moreover,a high-order dualband bandpass filter using multi-stub-loaded resonators is also introduced,a key merit of which is that the characteristics of the second passband can be conveniently controlled whereas those of the first passband remain unchanged.
