I have been needing a stable 10Ghz oscillator for a few projects I have been working on and was able to pick this brick up for pretty cheap. This is a Digital Microwave Corp 10.210763 GHz phase locked oscillator. This unit consists of a dielectric resonator oscillator that is phase locked to the x100 harmonic of a 102.10763 MHz crystal.
While not a YIG, it should be more than stable enough for my needs now (I hope). The new 10Ghz project will be coming after I finish up my 1420Mhz front end for the radio telescope which is nearing completion :)
