Many thanks for all your answers, I'll see what I can find in commercial pulse generators... I'm afraid I'm not good enough to make such a device on my own.
Greetings,
Sorry to bother you with such a trivial question, but I'm looking for a high frequency (>500 MHz) 2 channels square wave generator.
Do you know any material (not too expensive if possible) that would match these specifications?
Many thanks!
