摘要
RF单板的控制是一项非常重要的工作,由于某些射频单板调试过程中常遇到噪声系数过大的问题,文中以RRTB射频单板为例,利用DOE实验设计方法确定了噪声系数与器件(6个)之间的回归数学表达式,编制matlab程序求出了器件的最佳取值和组合。实验证明:利用DOE实验设计方法对射频单板低噪放问题有指导意义。
It is a very important work to control the RF（Radio Frequency） board instrument in the automatic test system of RF board.However,which brings much of noise figure in commissioning process of some RF board.In this paper,the regression mathematics expression of between noise figure and devices,the best values and the combinations of the devices are obtained by matlab program.Results show：the DOE has guiding significance to solve the problem of low-noise RF board.
