摘要
结合Smith圆图,利用微波大功率自动调配器测试系统,采用负载牵引法,给出搜索等功率圆曲线的算法。此算法在可以确定的圆方程上进行搜索,避免了在整个圆图中搜索很多个点再进行圆回归拟合的繁琐。等增益、等噪声都是可以Smith圆图中表示的圆,因此,此算法对以后其他参数的圆图搜索也有实际意义。
this paper adopts the load - pull to present the tracking algorithm for the output power contour on the Smith char by using the microwave power automated test system. This algorithm tracks on the determinate circle equation, avoiding the large number of experiment points for the circle regression. Constant gain and noise can also be described by the circles on the Smith char. So this algorithm has the practical meaning for the other characteristics＇tracking.
