请教各位高手。
发现每次打开MTK的ATE工具后,8960的线路补偿的频点都会变成如下表的值。请教高手他为什么要选这些频点来做补偿呢?.
AG8960_RF_Amptd_Freq_Offset Line0001 = "500000000,641000000,641100000,876000000,876100000,1312000000,1312100000,18800000"
AG8960_RF_Amptd_Freq_Offset Line0002 = "00,1881000000,2000000000,"
AG8960_RF_Amptd_Value_Offset = "-0.6,-0.6,-0.6,-0.6,-0.6,-0.65,-1.2,-1.25,-1.3,-1.35,"

TX / RX 補償 是要後端路徑到天線前端 rf switch 中間的power loss 補回去 才會是rf 進入天線所要的power
来学习了
