Thanks. Jim Robbins A quadrature-fed DBM produces the lowest jitter and noise. My implementation can be found at: <http://www.ko4bb.com/getsimple/index.php?id=download&file=02_GPS_Timing/4_App_Notes_and_Articles/Frequency_doubler_quadrature_DBM.pdf> A well-designed push-push frequency doubler is probably second (but note that many push-push designs you find on the web have various common design flaws).
