本文讨论了一种具有宽阻带的紧凑型低通滤波器。为了获得宽阻带，微带信号路径中嵌入了十个开路短截线，低通带带宽和杂散抑制可以通过顶部和底部的两个短截线进行调节。基于所提出的拓扑结构，制造了一个原型来实现 4.31 至 7.78 GHz 的宽阻带应用。实验结果表明新设计的过滤器可用。
A compact lowpass filter with wide stopband is discussed in this paper. To obtain wide stopband, ten open stubs are embedded into the microstrip signal path, the low passband bandwidth and the spurious suppression can be adjusted by the two stubs on the top and the bottom. Based on the proposed topology, a prototype was fabricated to achieve the wide stopband applications from 4.31 to 7.78 GHz. Experiment results demonstrate newly designed filter available.
