In this paper, one kind of miniaturized Gysel power divider (GPD) with ninth harmonic suppression is proposed. In this structure to weaken unwanted harmonics, radial and new trapezoidal‐shaped resonators are placed instead of the quarter‐wavelength transmission lines of the conventional GPD. Moreover, these resonators create eight transmission zeros and occupy small circuit sizes. For designing the proposed GPD, appropriate electrical lengths of transmission lines are selected. This GPD has high −15 dB fractional bandwidth, 71%, good isolation, > 15 dB, and compact sizes, 0.07 λg×0.22 λg. The operating frequency of the designed power divider is 2.1 GHz that can be used in many WCDMA applications.

紧凑的Gysel功率分配器,具有超宽的抑制带和高分数带宽

本文提出了一种具有九阶谐波抑制的小型陀螺功率分配器(GPD)。在这种结构中,为了减弱有害的谐波,放置了径向和新型梯形谐振器,而不是传统GPD的四分之一波长传输线。此外,这些谐振器产生八个传输零,并占用较小的电路尺寸。为了设计建议的GPD,选择合适的传输线电气长度。此GPD具有高的-15分贝相对带宽,71%,良好的隔离,>15分贝和紧凑的尺寸,0.07 λ× 0.22 λ。设计的功率分配器的工作频率为2.1 GHz,可以在许多WCDMA应用中使用。
