Actually, since my company makes all of the chips of consequence inside our products I am certain in what I say. Regarding the other chips, it is is irrelevant. Ls, Cs, Rs, Es, SOT23, etc, cannot be used for espionage. Our PAs come from the OEMs. What we do get via suppliers cannot be used for espionage.
I am not saying that it cannot be done and that the US should not be doing it, I’m just saying it does not happen in my companies products.
Like I was saying...
