| 摘 要： | 研究了一种改进型毫米波开槽波导空间功率分配合成网络。该功率分配/合成结构具有合成效率高且合成效率基本不受合成路数的限制、尺寸小、设计过程灵活和容易散热等特点。在详细阐述了其原理及设计过程的基础上,设计了一个中心频率为38GHz的Ka频段末端的功率合成器。仿真结果显示此种结构回波损耗小于-12dB的带宽达2.3GHz,相对中心频率带宽约为6%,且插入损耗小于0.3dB,可见具有极低的插入损耗和较低的回波损耗,从而验证了此种结构的可行性。

| Abstract: | In this paper,an improved slotted -waveguide spatial power divider/combiner circuit for Ka -band is presented.This circuit provides not only a high power-combining efficiency which is less depended on the combining way numbers over a wide bandwidth and flexibility in the design process, but also efficient in heat sinking.Its principles and design process are synoptically presented.A representative example of 38 GHz solid-state power amplifier is assessed. Result indicates that this circuit has a small inser... |
