Design of 16-Way High Power Divider

摘要

摘要: 为满足高功率微波辐射天线对其馈电系统的要求,针对现有高功率多路功分器的不足,研制了一种新型的高功率16路功分器.该功分器由同轴波导-4路矩形波导、H-T分支和波导同轴转换3个元件构成,其16路输出具有等幅同相的功率分配特性.设计了中心频率为2.85GHz的功分器,并对其进行了数值计算和试验研究.试验结果表明:该功分器在中心频率2.85GHz下,传输损耗约0.4dB,驻波系数为1.3,输出功率不平衡度约暲0.7dB,相位不平衡度约5;在2.78 ~ 2.92GHz的频率范围内(中心频率的5%带宽),传输损耗小于 0.6dB,驻波系数小于1.5.分析结果还表明,该功分器的功率容量瓶颈在输入同轴波导处,与内部其他结构无关,因而可实现对高功率微波源输出功率的分配.

Abstract: In order to meet the requirement for the feeding system of high power microwave (HPM) radiation antenna and overcome the shortage of current multi-port high power divider, a novel 16-way high power divider was developed. The novel high power divider is composed of coaxial waveguide- 4-way rectangular waveguide, H-T branch and rectangular coaxial waveguide, and the 16 outputs of the divider are characterized of equivalent amplitudes and phases. The 16-way high power divider was designed and tested with a center frequency of 2.85 GHz. The experiment results show that at the center frequency, the insertion loss is about 0.4 dB, the voltage standing wave radio (VSWR) is about 1.3, and the output power and phase imbalances are about 0.7 dB and 5 respectively. In the range of 2.78 to 2.92 GHz (5% bandwidth of the center frequency), the insertion loss and the VSWR are below 0.6 dB and 1.5 respectively. The input coaxial waveguide is the bottleneck of the power capacity of the divider so that this characteristic permits the divider to realize the power dividing of HPM source.
