Im am thinking about building a low power broadband jamming device to blanket a small area, around 400 sq.ft. I want my frequency range to be from DC to 100 ghz. Would amplifying the outputs of noise diodes that are summed to produce this broad a frequency range be the cheapest way to build this device? ( please don't mention in your answers that jamming devices are illegal: I know and I don't care. This is for scientific research only). Thank you!

It probably is the cheapest way looking at how others have done it - as far as you must be "truly" broad in the interference.

  • Maxim has a application note on how to build a white noise generator. Apart from your range demands this seams like a nice way to do it.
  • Googleling gives a few more examples etc. However most are not not meant to be broadcasting.

And some not so wide examples (that are meant to be broadcasting):

  • Adafruit have blueprints for a jammer (that is not as wide as you wish) (but no kit for sale)
  • iinstructables have more than one jammers (but they are mostly narrow)

Not a good answer to your question, sorry but I hope it can help you.

  • \$\begingroup\$ Np, and like you say I don't know what you are doing so I simply assumed you have the proper permits if you go and do something like this. \$\endgroup\$ – Jontas Aug 6 '12 at 9:57
