If easy means a temporary lashup, takes but one piece of gear. The
Ballantine 6130A time mark generator takes in 10 MHz, produces from
it a synchronous 1Hz to 500MHz selectable in 1-2-5 steps. I've not
tested mine for phase noise, probably
not the best performer... but for $35 not a big concern, given my
needs.
Shameless plug: I'll have another one for sale at the Dayton
Hamvention, flea
market space 1901. There will be other Time Nuts in residence at 1901
as well.

Is there any fairly easy way to multiply the output of a Thunderbolt
to
have a 500MHz reference at about 4dBm? Thanks.

******************************************
Bob's suggestion to get a Ballantine 6130A Time Mark Gen might be your
easiest solution if this is a one-off project. According to the schematic,
the 10MHz oscillator is sent through a series of multipliers and filters to
arrive at the 500MHz High Freq output. Specifically, it goes through a
doubler and two quintuplers.
I don't know how the unit is constructed (I only have a schematic, not the
complete manual), but if the RF circuitry and the digital dividers are on
separate boards, then you might be able to use just the RF board to
construct your 500MHz signal. (I'm assuming that your intent is to
construct the project into a single enclosure).
The only other solution that might be easier would be to find a PLL board
that can be programmed to output your 500MHz signal. I looked over eBay and
Google without much luck there.
Good luck with your project.
