Dear all,
?
Finally the parts arrived, and I started the IC changes.
?
First, I removed the U22 0 ohm resistor, working as jumper, and place the RF Switch, and do recall. During recall it fault again, so I decided to change the LNA, U16.
After changed it and recall, the calibration from 100kHz to 5.327GHz goes succesfuly, and I passed to calibrate abovde 5.327GHz.
I've no idea that you need to generate signal from other device, so I used an ADALM-Pluto to generate the signal and power enough for calibration, and succesfuly it worked again.
?
So now, my device is perfectly working and calibrated and I can play again with it.
?
Many thanks to everyone for the help and we're in touch.?
?
Sincerely,
?
Jorge EA1FWI.
