hi

can analogue amplifiers be activated with radio frequency ?


thanks

 

Not sure what you mean by that question. I sounds as if you are talking a form of Radio Control, which is pretty routine.

I am moving this into the electronics chat, where it is a better fit.

 

Sure they can. Just lay your Cell phone near the unused inputs of a home stereo system.

You mean, can amplifiers be powered by ambient RF? The answer is yes, and it's becoming a popular way to power things like remote sensor transmitters, etc.

I don't have a circuit at hand, but I experimented with RF-powered amps back in the 1950s, when the transistors were first sold to the public.
