thank you gentlemen of patience, sorry if at the beginning it was very confusing, but then I chose the most suitable solution for me and that is the radar. However, the frequency multiplier that you spoke to me therefore serves to increase the frequency while leaving the power unchanged? Because in fact, as I said, I only need a frequency higher than 1 ghz and therefore I am not even interested in modulating except to increase the frequency with the beats. So if I use a transitor with 1200 watt power and 500 mhz frequency, can I multiply the frequency to my liking? If so, as I understand then tell me how it works so we have resolved the discussionIt is not just a question of frequency, but power levels as well. My precise question is: "What is the purpose of both the frequency AND the power level"?
