This circuit will buffer the OCXO's output and feed it through a power divider so it can go both to the final output distribution board and the phase-locked loop controls.  It's a low noise circuit that will compensate for power divider losses and isolate the oscillator from downstream noise.

I'm experimenting with circuits designed by KO4BB and adapting them to my needs.


This started as a quest to build an atomic frequency standard based on a rubidium oscillator.  After realizing that I could get much better short-term stability and long-term accuracy by building around an ovenized crystal oscillator that's disciplined to a GPS time reference, the project was retargeted.
