1-V3 high-freq signal issue.
customer complaint"poor recpition".
use GPGATE software to test RX and TX with Aglient-8960;
TX(850.900,1800,1900)pass
RX(900,1800,1900)pass but only 850M error message"AGC unstable";
i check
1-26Mhz OK,CLK,DATA,CS signal from neptune are ok.
2-rep PA,U150,FL100 and it's still error message.
3-i take off Neptune and Flash and resolding to other V3 PCB and do RX,
it's pass.
so who guy can help me what's caused "AGC unstable"
AGC="auto gain control"
