摘要:
提出了一种采用非对称叉形枝节加载的新型三模谐振器,并对该谐振器结构特性进行具体分析.该谐振器具有3个非谐波模式,可以通过调节非对称叉形枝节的电长度进行单独调节.利用该三模谐振器在0.8 mm厚的介质基板上设计了一种中心频率分别为2.08、2.42和3.04 GHz的紧凑型三通带带通滤波器,并且通过0°抽头馈线引进额外零点提高了滤波器的选择性和阻带抑制效果,测试结果与理论分析相吻合.
Abstract:
A novel Triple-mode resonator using asymmetric fork stub-loaded is proposed in this paper:The modes of the resonator can be independently controlled by adjusting the electrical length of asymmetric fork stub-loaded.A tri-band filter with three center frequencies at 2.08 GHz,2.42 GHz and 3.04 GHz is designed and fabricated on 0.8-mm substrate.The measured results are given and show a good agreement with the theoretical analysis.
