各位大神:
近期在测试MSM8916平台时:发现在整机测试的过程中,BT/WLAN/GPS三者的发射功率超出规格,Fail Log如下:
BT:BT_RAD_MEAS_CW_POW_CH_39 (下限:-5 ,上限:5 ,实测值:15) NG
BT_RAD_MEAS_CW_POW_Status _CH_39 (下限:0,上限:0, 实测值1) NG
WLAN: WLAN_2.4GHZ_RAD_MEAS_CW_POW_LCH01_CL (下限:10,上限:28, 实测值:31) NG
WLAN_2.4GHZ_RAD_POW_Status_LCH01_CL(下限:0,上限:0, 实测值1) NG
GPS: GPS_CARRIER_TO_NOISE(下限:55,上限:65,实测值:72.6) NG
GPS_OVERALL_Status (下限:0,上限:0, 实测值1) NG
对于此问题有更换3in1 IC和天线和线路上部分的零件;望各位帮忙解惑,多谢!

我觉得应该从三者共用的信号和电压入手,好好查一下电路图应该能找到问题
