Hello.
I need to sum short (~ 1 ns) pulses. Such pulses have a rather wide spectrum (several GHz). Initially, I want to get a larger amplitude impulse. That is, add 2, 4 pulses to get one with a large maximum value, but approximately the same duration.

I am thinking of using Multistage Wilkinsons based adders for this. Maybe someone faced with a similar task, saw the publication or just be able to help with advice.
