摘要

对一种用于蓝牙接入点的相控阵天线的4位分支混合耦合移相器进行了完整的分析。该分析基于不考虑衬底材料损耗的传输线等效模型。分析了不同相位组合的级联移相器的性能。在反射网络上允许不同的阻抗值，以获得额外的自由度。在此基础上，制作了一个4位混合耦合移相器。理论分析结果与实测结果吻合较好。

Analysis of 2.45 GHz 4-bit hybrid-coupled phase shifter for phased arrays

A complete analysis of 4-bit branchline hybrid coupled phase shifter for a phased array antenna operated in a Bluetooth access-point is presented. The analysis is based on the transmission line equivalent model which does not take account the losses of the substrate material. The analysis includes the performance of the cascaded phase shifters with different phase bit combinations. Different values for impedance on the reflective network are allowed for having an additional degree of freedom. Based on the theoretical results a 4-bit hybrid coupled phase shifter is fabricated. The results of theoretical analysis agree well with the results obtained from the measurements.
