摘要
针对传统大功率多路功分器带宽窄体积大的问题,提出了利用四分之一波长阶梯阻抗变换原理,设计超宽带的多路功分器的方法。这种设计方法不仅解决了多路功分器各级之间互联线造成的带宽变窄的问题,而且还利用互联线实现了超宽带的阻抗匹配。最后采用上述方法设计了工作在0.8-6.0 GHz频带内的超宽带八路功分器,获得了的驻波比小于1.4,采用同轴腔体结构,插损小于0.8dB,完全可以满足电子对抗工程中对于超宽带大功率合成的需要。
Aimed at the problems of narrow bandwidth and large volume in the conventional multi-way power-divider, the design way of UWB multi-way power-divider is presented based on the principal of k/4 step impedance transformer. The design method not only solves the problem of narrow bandwidth caused by the interlink-lines among the all the levels of multi-way powerdivider, but also realizes UWB impedance match by using interlink-lines. A UWB 8-way power-divider is designed based on the method described above. This 8-way power divider operating in the frequency range of 0.8GHz-6GHz, has VSWR of less than 1.4 and insertion loss of less than 0.8 dB. The design can completely meet the application of large power combined in the ECM.
