TRAPATT diodes -- looking for sources of parts

  1. Jul 24, 2017 #1
    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:

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

    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.)
