[Hackrf-dev] Amp On or Off

[Tom]

Thanks Mike,

Have you experienced any blown RF amps due to overloading ? if so do you
know what the specifics were that caused the failure?

The important thing to realize about safety of the RF amplifier is that
frequency is irrelevant.  The amplifier sees 6+ GHz of bandwidth regardless
of what frequency the HackRF One is tuned to.  If you are sitting right next
to a powerful transmitter at 100 MHz, it doesn't matter if you tune to 100
MHz or 1 MHz or 6 GHz; the RF amplifier is affected the same way in all
cases.

I tried to make this clear in this video:
