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.
