麻烦各位大神，想问一下4G功率校准原理，为什么输出功率从二十几dB降到十几dB时，PA增益几乎没啥变化，校准不是校准的PA增益吗?（MTK 6169PA ）?
Pa control dc2dc level=0.6V,0.8V,1.0V,1.3V,1.7V,2.0V,2.8V,3.4V
Pa control level=8
Pa control pa gain=25.75,26.2188,26.5312,26.9688,27.3125,27.5,27.8125,28.0625
Pa control pa mode=L,M,M,H,H,H,H,H
Pa control prf=0,6,10,13,16,18,20,23
是通过这几项实现校准的吗?具体原理大概是啥?

求大神解答！
电压啊，亲，还有LMH
