BAND2 TX SUBBAND FAIL

CTC168

请教大家一下，BAND2的平坦度怎么调试:

Calibration and NSFT total cost time is: 59.30s

Subband Calibration 的值也没出来。

小弟刚做射频，遇到难题，求大神指点。

首先你的雙工器有沒有調試收斂，不收斂的話高中低信道性能很容易差異大

感谢兄台。

调试双攻ANT端匹配

metalsi

你这个原理图看上去应该没什么问题，MURATA的这个双工器参考ANT对地电感式3NH，实际测试一下高中低三个信道的包和功率，看看差异大不大。如果大，先调双工，如果调双工没反应再调功放输出匹配。

可以使用META调整吗

调匹配吧，一般都是匹配引起的。
