Hi If you have a one time need to get to 1.3 GHz then some sort of cobbled together dead bug chip solution would be my pick of how to get it done. Cost wise it wold be hard to beat. There are also cooled up approaches with signal generators and mixers ( no don’t go there …).
If you will be doing this a lot and handling a variety of signals, get a real instrument prescaler (or a counter with one built in). There are a lot of weird things a good design will address that makes it a more pleasant thing to use. If I was shopping, I’d go a bit higher than 1.3 GHz. You never know what you might need next year :) The good news TimeNut wise is that all of the approaches are just simple dividers. Sensitivity, modulation acceptance, and immunity to going off into freerun modes matter. If they lock up, all the approaches I’m aware of are equally accurate.
