I can't figure out how tf a tunnel diode is supposed to amplify a signal

My guess is that you need a reverse bias as power supply, but my brain is too mushy to figure out how exacrly and all the example diagrams on tunnel diodes are just resonators

Oh wait, you could also have a dc offset on your signal and draw power from that? Now it kinda looks like when you make sure a transistor never turns fully off so it can switch faster ig

Still not sure, wouldn't that cause your signal voltage to drop to the supply voltage?

@snacks negative resistance creates power

@twinspin6 no really, where does the energy come from

@twinspin6 10ghz amplifier for about a buck a pop, cmon

@snacks so the diode is biased and then the bias is removed at the output

@twinspin6 actually looked at tge resonators. Seems like power comes from a forward bias while signal is applied reverse. Ig my brain was too stuck in transistors where input and output are cleanly seperated instead of just yk, amplifiyng the signal where it is

@twinspin6 also, why is this one of these technologies where you can russian stuff for cents while in the west it's only rare hyper expensive parts

@snacks doesn't matter it's microwave bs

@twinspin6 doesn't that just stop the signal from being fed back into the power supply?

@twinspin6 i think i like the resonators better now that i understand wtf a tank circuit does

@snacks me too (i only know some theory)
