Best way to build fixed 1.6GHz locked oscillator?

Hi,

I'm in the process of designing a simple scalar network analyser. The
synthesizer will use 2 PLLs. One tuning from 1.6 to 2.6GHz and the
second on locked to 1.6GHz. I hope to create a DC to 1GHz output. I'll
use Minicircuits or similar for the broadband VCO. But it seems a
little wastefull to use the same thing for the fixed frequency PLL. So
here's the question, what would you experienced home brew gurus
recommend?

The oscillator phase noise does not have to be perfect, but it should
not be much worse that the Minicircuits VCOs. The cumbersome
old-fasioned multiplied crystal is not really needed. So what other
options should I look at?

Thanx for ideas,
