Would you give me URL about some IEEE papers about DRO ?
you're welcome
a google search will probably bring up some results for you
I use DRO's where stability isnt of high importance like in TV transmitter / receiver applications at 10 and 24 GHz
When the TV signal is ~ 8HMz or so wide, several 100kHz of drift isnt a real problem
DRO's can be phase locked and I have a 24GHz system that does that.
Another suggestion that no one has mentioned and I forget to..... you might want to consider YIG oscillators. They are available for many freqs and on ebay I have bought ones that cover 8 - 10GHz and 9.2 to 11.2 GHz. These are also able to be PLL'ed have a look at this example from ebay...
**broken link removed**
this is the same style as the units I have. YIG's also have reasonably good phase noise
Stellex’s YIG [Yttrium Iron Garnet] technology provides a frequency source with high spectral purity for high-frequency communications applications.
Mini-YIG Tuned Oscillators
• 9 GHz in Center Frequency
• Low Phase Noise
• –105 dBc/Hz @ 10K (typ.)
• –128 dBc/Hz @ 100K (typ.)
• Up to ±1 GHz Tuning Range
• Output Power +14.5 dBm (typ.)
• Outstanding Phase Hit Performance in 64 and 128 QAM Radio Systems
• Offered in SMA Connector Package

That link in Bigboss's last post will take you to an articl on DRO's and the bottom of the article are a lis of references that includes a number of IEEE papers
