本文提出了一种具有差分输入输出端口的功分器。该功分器由三个耦合谐振器组成，具有带通滤波器响应。因此可以获得良好的频率选择性。在RO4003C基片上制作了一个2.45 GHz的差分功分器，并用矢量网络分析仪进行了测量。实测数据和仿真结果表明，与传统功分器相比，该功分器具有更好的频率选择性。从模拟的电流分布，可以验证差分输入信号在输出端口处的差分操作。
A power divider with differential input and output ports is proposed in this paper. The proposed power divider consists of three coupled resonators and exhibits a bandpass filter response. Good frequency selectivity could hence be obtained. A 2.45-GHz differentially operated power divider has been fabricated on an RO4003C substrate and measured by a vector network analyzer. The measured data as well as the simulated results show that the power divider has a better frequency selectivity compared with a traditional one. From the simulated current distribution, the differential operation at the output ports with the differentially input signal could be validated.
