Abstract

Concept, design, and results of a novel miniature suspended stripline (SSL) filter type based on an interdigital filter structure with quasi-lumped elements are presented. The filter is realized in a metal channel of 4.25 mm × 5 mm. Compared to a standard SSL resonator, length is reduced by about 75%. A three resonator filter at 7 GHz with a 450 MHz bandwidth is demonstrated, having a filter length of only 12 mm and losses of about 1.4 dB, including 18 mm of excess transmission line and the transitions to coaxial line. Further examples are a three-resonator filter at 11 GHz and a 8 GHz five-resonator filter.

一种新型微型悬浮带状线滤波器

提出了一种基于准集总元的数字间滤波器结构的新型微型悬浮带状线(SSL)滤波器的概念、设计和结果。该滤波器是在4.25 mm × 5 mm的金属通道中实现的。与标准SSL谐振器相比，长度减少了约75%。演示了一种带宽为450 MHz的7 GHz三谐振器滤波器，其滤波器长度仅为12 mm，损耗约为1.4 dB，其中包括18 mm的多余传输线和向同轴线的过渡。进一步的例子是11 GHz的三谐振器滤波器和8 GHz的五谐振器滤波器。
