TRAPATT diodes -- looking for sources of parts

AI Thread Summary
TRAPATT diodes, or TRApped Plasma Avalanche Triggered Transit diodes, are specialized avalanche diodes that generate short pulses of microwave energy but are considered outdated due to their high noise levels. Users are struggling to find manufacturers or sources for these diodes, as they seem to be a niche application from the 1970s. Relevant literature, including a 1977 document on TRAPATT amplifiers, is available for those interested in the theory and characteristics of these devices. Experimenting with general-purpose diodes in TRAPATT mode may lead to significant risks, including overheating and damage. Overall, the discussion highlights the challenges and potential hazards of working with TRAPATT diodes.

Hello everybody,
I wish to do some experiments with TRAPATT (TRApped Plasma Avalanche Triggered Transit) diodes, but after much googling I was unable to find the name of any manufacturer of such diodes.

Anybody with useful pieces of info?...
Thank you! :bow:
 
Engineering news on Phys.org
A TRAPATT diode is an avalanche diode, operating in a mode that produces short pulses of microwave energy.
The mode is no longer used as they were high noise devices, a product of the 1970s.

Thank you very much to both of you... Ouch! It seems quite an adventure! Driving a general purpose diode into a region that, of course, is not covered nor described in its specifications... I forecast a lot of smoke and smell of burned plastics in the near future! :oldbiggrin: :angel:

Ahh yes! The sweet smell of an overworked component. Please keep us updated on how much of that "magic smoke" you release into the wild! (and how.)

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
