Is there a preferred frequency doubler circuit which would do the least harm to
the ADEV of the oscillator? The signal can be a square wave and does not need
to be a sine wave. Thanks. Jim Robbins
A quadrature-fed DBM produces the lowest jitter and noise. My
implementation can be found at:

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). My implementation can be found at:
