UWB Exciters

@All

I don't want to change Mike's direction at all, but will throw out some additional info about obtaining the frequencies you want.

If you use doubler's, tripler's etc., you can design them so that they are for the most part immune fro non-desired input frequencies by using a combination of input filters (bandpass) and a high Q tank for the output stage. Therefore its a matter of good engineering and the art of RF to reject what might be present that you do not want.

What we do at my lab is use one of my exciters into a SGATE which gives a pretty level output across hundreds of megahertz.

*Side note for that 'PestWicked' fellow that made the remark that I could not substantiate UWB from my Exciters in the Diode Electrolysis Videos, LOOK CLOSELY.

Okay to explain what a SEC Exciter and SGATE can do, here are a few picture from an SA to show what not many of you have seen do to not having the needed equipment.

What I do is adjust the exciter for the spread I desire and bridge off the specific frequency I desire.

I would think this would be much easier than all the oscillator, doubler and triplers, just bandpass and amplify what you want, pic the candy from the selection so to speak.
