Hello again,
Just for update about the thread, I've disassembled the TinySA and remove the U22, the RF Switch, and replace it by 0R jumper joinning traces.
The result is that the power values from CAL connector in 30MHz Output mode goes to normal values and "Safe Test" near pass succesfully. However when it needs LNA to measure it fails, which is normal, becouse know as I don't have RF switch it can measure anything in that trace.
I tried to calibrate it is not possible to finished it becouse also needs the LNA, but now the power values has more sense.
Probably I've to replace to the LNA, which I think is U14,and it will get back to the normally, but I need to know the PN to buy them.
?
Could you tell me what are them?
?
Thanks in advance.

Greetings,
Jorge.
