| 摘要: |
| 首先介绍了使用定向耦合器和Wilkinson功分器对箭上遥测信号进行不等分功分的原理，在此基础上，分别用这两种方案实现了S波段射频信号10∶1不等分功分，并对二者的性能指标进行了仿真研究和分析比较，结果表明，无论是产品自身的可靠性，还是在性能指标方面，采用改进型Wilkinson功分器均优于平行线定向耦合器，为工程应用提供了参考。 |

| Abstract: |
| The principle of using directional coupler and Wilkinson power divider for unequal power dividing of the telemetry signal of launch vehicle is illustrated. On this basis, the unequal power dividing of 10∶1 at S band is realized using the two ways mentioned above and the performances are simulated and compared. The result indicates that modified Wilkinson power divider outperforms directional coupler on both reliability and characteristics, which is helpful for engineering application. |
