If you mean the quadrature hybrid, I use an FT37-61 toroid core. One of
the smaller Mix 61 balun cores should also work, but with the

A quadrature-fed DBM produces the lowest jitter and noise. My

Hi
The simple answer is that most doublers that are ok for phase noise will not
degrade ADEV.
The issues with ADEV come when your doubler is out in a changing environment
and your
oscillator is not ( = it’s an OCXO). The answer to that problem is pretty
simple if you have an issue …

Would doubling the frequency of a 5 MHz oscillator to 10 MHz affect (or
degrade) the natural ADEV of the 5 MHz oscillator? If so, how does it affect
the original ADEV? Is there a preferred frequency doubler circuit which would
do the least harm to the ADEV of the oscillator? The signal can
