Wireless communication and microwave are usually encountered with nonlinear effect, and nonlinearity is

Zinc Negative Resistance RF Amplifier for Crystal Sets.

In addition, negative resistance amplifiers do not seem well suited for amplifying the audio output from a crystal set because of the low impedance that is usually required to drive the amplifier. Using a negative resistance amplifier to amplify an RF signal however, is a much more straightforward task as only one frequency need be amplified ...

The negative resistance would cause the AC currents inside To amplify to a point it would damage the tube. Even sudden fluctuations in input voltage could instantly destroy the florescence tube. With that logic let's experiment some more with our modified LED.

I figured that using an amplifier with a negative output resistance would have an effect that's equivalent to decreasing a speaker's Qe value, and thereby improving its boxed midrange performance. The same thing could be done mechanically by replacing the magnet with a much stronger one, however this gives a skewed frequency response with ...
