本文提出了一种工作在2GHz左右的紧凑型高性能反射式移相器。它通过使用非常紧凑的横向耦合器和简单的可调反射负载在标准PCB技术中实现。电路大小等于0.29 · 0.1$\lambda _g^2$。在不牺牲性能的情况下实现了这种小尺寸;由最大相移除以最大插入损耗的比值给出的品质因数在2.15 GHz时达到169°/dB，与文献中公布的平均性能相当。所展示的小尺寸为实现非常紧凑的相控阵射频馈电网络铺平了道路。
In this paper, a compact and high-performance Reflection-Type Phase Shifter operating around 2 GHz is proposed. It is realized in standard PCB technology by using a very compact transdirectional coupler and simple tunable reflection loads. The circuit size is equal to 0.29 • 0.1$\lambda _g^2$. This small size is achieved without sacrificing performance; the figure of merit, given by the ratio of the maximum phase shift divided by the maximum insertion loss reaches 169°/dB at 2.15 GHz, which is comparable to the average performance published in the literature. The demonstrated small size paves the way for the realization of very compact RF feeding networks for phased arrays.
