Right now, the performance is really good up to 3.5 GHz : 50 MHz : -7 dB 100 MHZ : -15 dB 250 MHz : -26 dB 500 MHz : -30 dB 1 GHZ : -32 dB 2 GHz : -32 dB 3 GHz : -30 dB
The real deal on the performance of prescalers is the ability to count noisy sources. If you did these tests with a pristine source, they don't mean much unless all you ever want to measure are pristine sources. You also didn't mention how many significant digits of accuracy you verified. A marginal prescaler might look good for the first half dozen or so digits but make errors beyond that. I like to see at least 10 digits that are not only stable but correct; they can be stable but incorrect.
