Solution was reball rf ic and solder again, now works fine. Perfect in 900MHz a little dropping sifgnal in 1800MHz

sorry mate

well , i have no picture for t200, but is the same chip, in t200 is in the same place, a little more uper because the PA is in the left side and the fr ic is in the place occupied by Pa in t68 on the right side under the external antenna connector.

hope help you mate, sorry for bad english b/r
