Hi all experts,
I have encounter problem in the power control loop in my project. My Tx power is lower than half when I tested at -30 degC compare with room temp. It is also become unstable and need some time (> 1 mins) to lock the output power to a specific value.
I had checking on the Pre-driver and PA, all is working fine. Based on your experience, what experiments or actions need to do to solve this issue? Anything that I miss up?
Between, May I know where can I getting much information regarding power control loop?
Thanks in advance!
