本文提出了一种小型化的高选择性带通功率分配器，并对其进行了理论分析。基于耦合谐振器拓扑结构，所提出的功分器的电路面积可以随着组装谐振器的尺寸缩小而减小。因此，为了有效地减小电路面积，提高阻带性能，选用了网状谐振器来设计滤波功分器。为了演示，功率分配器与切比雪夫和准椭圆带通响应已被设计和制造与微带印刷电路板。每个功率分配器的高度对称结构提供低带内幅度和相位不平衡。因此，所提出的滤波功分器具有尺寸小、边缘选择性好、隔离度高和带外性能上级等优点。所有测量结果与全波模拟结果吻合良好。
Miniaturized power dividers with high-selectivity bandpass behavior are presented and analyzed theoretically in this paper. Based on the coupled-resonator topology, the circuit area of the proposed power divider can be reduced as the size of the assembled resonators shrinks. Therefore, in order to effectively reduce the circuit area and improve the stopband performance, the net-type resonator is selected to design the filtering power dividers. For demonstration, power dividers with Chebyshev- and quasi-elliptic bandpass responses have been designed and fabricated with microstrip in printed circuit boards. The highly symmetric structure of each power divider provides a low in-band magnitude and phase imbalances. Consequently, the proposed filtering power dividers have advantages of small size, sharp skirt selectivity, high isolation, and superior out-of-band performance. All measured results are in good agreement with the full-wave simulation results.
