sky77550 讨论

rsdczw · 发表于 2013-6-7 19:31:24

平台：6515+6163+77550，，

问题：功率gsm L5是ok，
，L169-L19的功率大了，最小功率9db，用尽办法，
gsm19的功率只能达到9db，，高于要求的5db，，，
修改vapc的分压电阻也不行，，

有人用过77550么？求解啊[em03][em03][em03][em03][em03]

ramp 加分压电阻，调整PA VRAMP分压试试。

rsdczw · 发表于 2013-6-9 13:40:06

pa的输入正常的，

mozhefoxin · 发表于 2013-6-8 16:53:38

楼主看看PA输入是多少？是不是TR出来的太大了呢？如果太大了加个衰减网络看看，一般PA输入放在2 3dBm可能会比较好点
