摘要

本文研制了一种适用于全球定位系统(GPS)和固定卫星(FS)的双频带通滤波器。该滤波器是由缩短长度的平行耦合线组成的平面结构。采用级联耦合线设计了双频带滤波器。实现了两个通带之间的高隔离。与以往的工作相比，该滤波器在1.5 GHz和7.5 GHz时具有更低的插入损耗。采用厚度为0.508 mm的Arlon DiClad 880衬底，实现了15.7 mm × 33.4 mm的紧凑尺寸。

Design of a compact dual-band band-pass filter for Global Positioning System and Fixed Satellite applications

In this article, a dual-band band-pass filter is developed for Global Positioning System (GPS) and Fixed Satellite (FS) applications. The filter is a planar structure composed of parallel coupled lines with reduced length. The dual band filter is developed using the cascaded coupled lines. High isolation between two pass-bands is achieved. Compared to the previous works, the proposed filter has lower insertion loss at 1.5 GHz and 7.5 GHz. A compact size of 15.7 mm × 33.4 mm is achieved for the proposed filter using Arlon DiClad 880 substrate with a thickness of 0.508 mm.
