Hi everyone! What I'm trying to make is a circuit for a biologist friend studying the effects of absence or presence of artificially produced frequencies on guinea pigs brains. It's an advanced study I don't get very well but he asked me if I could help him in making a circuit which would produce every possible frequency from 1Hz to 100Mhz simultaneously. Pretty much a white noise generator reaching rf spectrum and a linear amplifier and small wire antenna in order to transmit the rf spectrum in space. I told him that (from what I know) this spectrum would be difficult to be covered by a single generator. But I could try a 10Khz to 10Mhz which would be much easier for linear amplifiers. Since he needs to cover an area of 30sq meters, I think 500mW or less should be enough.
I found some noise source circuits online and I think the "avalanche diode" method is the simplest and more promising one. So I'm thinking of making the generator in the picture below, but how you think I should proceed for an amplifier of this spectrum?
