Did I ever say that? No. Someone questioned the fact that I stated that a resistor has a self resonant frequency. I have never claimed that it mattered in an HF amplifier. Also, I even stated in onc

We are both right on this one...let me explain: If you are driving an amp non-linearly with a CW signal, then no, you won't produce intermod distortion. This is the reason that a class C or a class

I would say that with the right set-up, you could go even lower. I know people who do IM measurements on connectors. The IM generated by a connector interface can be on the order of -125 dBc. And ye

IMHO, yes you can do this sort of thing. However, it isn't easy and can be quite complicated. In my engineering days, I was part of a design team that developed several linear amplifiers that were f

HUH? How can a magnetic field bend carbon? Last time I checked carbon was not a magnetic material. I think Carl here is just trying to throw stuff out here to confuse the issue. Junk science to coin

What do you call cutoff? Zero mA plate current? It certainly wasn't keyed and was just idling. Even in class AB operation some current is likely going to be drawn as just quiescent current. Idle cur
