Richard: Generating a second harmonic is easier, using a push-push diode doubler. MCL (Mini-Circuits Lab) should have some available at reasonable cost, but I didn't check their catalog. You could also build one yourself if you have the parts and facility. I know this doesn't get 10 GHz., but it is possible to cascade two of these. Using a 3-6 dB pad between them and at the output, as you suggest, is important.
