TRAPATT diodes -- looking for sources of parts

[Majorana]

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!

1N5408. TRAPATT seems to be a specific use of some ordinary diodes.
See last paragraph on page 2 of article:

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!

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.)
