Abstract

In this work, a high degree of miniaturized Gysel power divider (GPD) along with harmonics suppression is presented. Firstly, a GPD consisting of three kinds of quarter wavelength lines (QWLs) is designed based on the conventional technique at 0.9 GHz which serves as the reference GPD. To reduce the circuit area of this reference design, conventional lines are replaced by multiple transmission line techniques like coupled line-based transmission line, dual transmission line and T-shaped transmission line. As a result of this, the overall circuit area of the reference GPD is reduced by 80.4 %. Moreover, 2nd, 3rd, and 4th orders unwanted harmonics are suppressed by a level better than 19 dB, 12 dB, and 11 dB, respectively.

高度小型化的Gysel功率分配器，采用多传输线技术抑制谐波

在这项工作中，提出了一种高度小型化的Gysel功率分配器（GPD）以及谐波抑制。首先，在0.9 GHz的传统技术基础上，设计了由三种四分之一波长线组成的GPD作为参考GPD；为了减小本参考设计的电路面积，采用基于耦合线的传输线、双传输线、t型传输线等多传输线技术代替传统的传输线。因此，参考GPD的整体电路面积减少了80.4%。此外，二阶、三阶和四阶不需要的谐波分别被优于19 dB、12 dB和11 dB的电平抑制。
