摘要/Abstract

摘要： 提出一种新型的、中心频率可独立调谐的双频带通滤波器(bandpass filter, BPF). 该滤波器由加载双端短路枝节的阶梯阻抗谐振器(stepped-impedance resonator, SIR)和双模开口环谐振器构成. 二者共用输入输出耦合线, 产生额外的传输零点, 提高了滤波器的选择性. 通过奇偶模的分析方法, 在谐振器末端加载变容二极管, 以调节奇偶模谐振频率来达到电调的效果. 结果显示, 第一通带的可调范围为1.93~2.20 GHz, 第二通带的可调范围为2.78~3.10 GHz. 比较仿真与测试结果, 证明了该方法的有效性.

Abstract: A dual bandpass filter (BPF) with two center frequencies tuned asynchronously and independently is presented. The proposed filter consists of a stepped-impedance resonator (SIR) with two-terminal shorted stubs and a dual-mode open-loop resonator. To generate additional transmission zeros and improve frequency selectivity, the common input and output coupling lines are used for these two structures. Using the odd-even mode analysis method, resonant frequencies of odd-even mode are electrically tuned due to the loaded varactors at the end of transmission line. The measured performance shows that
the first passband can be tuned in a frequency range of 1.93~2.20 GHz, whereas the second passband varies from 2.78 to 3.10 GHz. Comparisons of simulated and measured results show effectiveness of the method.

Key words: bandpass filter (BPF), dual-band, electronically tuned, odd-even mode
