【摘要】 本文提出了一类集成滤波功能的功分器,在原有威尔金森功分器的基础上引入谐振器,实现了滤波器与功分器的集成化设计,采用了新型的隔离机制,获得了输出端口之间良好的隔离。每个通带两边都有一个传输零点,较好地改善了电路的选择性。相对于级联的功分器与带通滤波器而言,我们所提出的电路具有更小的尺寸和更低的插损。为了进一步说明,我们仿真并测试了这三个电路。仿真和测试结果与理论分析的结果具有良好的一致性。更多还原

【Abstract】 In this paper, a novel kind of power dividers integrated with bandpass responses is proposed. By introducing resonators to the Wilkinson power dividers, the dual functions of power splitting and signal filtering are integrated in one component. Good isolation performance is realized by utilizing novel schemes. Moreover, two transmission zeros are generated at the both sides of the passband, resulting in high selectivity. Compared with a cascaded power divider and bandpass filter, these proposed circuits exhibit compact size and low loss. For demonstration, three circuits are implemented. The simulated and measured results are shown to validate the analysis.更多还原
