摘　　要：为了提高在室内信号合成平台背景下使用的小型化合路器功率容量,采用矩形同轴线设计了一种双频合路器,其新型的并联带阻滤波器结构具有良好的阻带特性和更大的功率输出,实测达到的500 W与国内外300 W主流的小型化合路器比较,有效提高了功率容量。首先对矩形传输线的传输特性进行了理论分析,随后通过全波软件仿真设计了矩形同轴线双频合路器,并进行了实物制做和测量,仿真和实测结果吻合。该合路器具有大功率、低损耗等优点。This paper focused on a dual-band combiners which effectively improves the power capacity,using parallel band-stop filters with rectangular coaxial structure.Compared with mainstream domestic and foreign 300W devices,the 500W combiner effectively improved the power capacity.The theoretical analysis of rectangular transmission lines was presented as well as the design of rectangular coaxial dual-band combiner with full-wave simulation software.The simulation results agreed well with experimental results after physical processing and measurement.The combiner has significant benefits on high-power and low loss.
