Hi everyone
I'm trying to build HF amplifier for scintillator, but it's still catching some noise on oscilloscope (see pictures). Amplifier is mentioned for fast pulses. I tried put it to metal case to avoid inducted voltage, but it doesn't help. Does anybody have some idea what cam be wrong?
On photo you can see signal without noise which is there for most of the time, but on the second one you can see noise - I have no idea where it come from.
As amplifier Im using TQP3M (Qorvo company), circuit scheme is from their datasheet.
Thanks for your help
