Gerhard, you didn't mention a budget number for this. You should be able to find a commercial synthesizer ready to go if you have enough money. If it's a one-off, DIY thing, then it's a different story. If this is the case, I'd recommend looking at the methods used in microwave counters. They

Wenzel Associates (www.wenzel.com) In Austin TX can build custom rack mounted multiplied very low phase noise crystal sources. I have used their custom microwave multiplied crystal sources at my pre-retirement job (Tektronix RF Application Engineer) with a 12.5 GHz output. A few of my customers
