Hello all, sorry for the OT, but the electronic expertise of the group is too good :-)
I'm looking for ideas and directions (articles and so on) to realize very good phase noise xtal oscillator, in the range 20-50 MHz for high performance frequency conversion. I would like to understand what circuits can be realized (not requiring too much professional and modern equipment, test eq. from the 70s-80s is ok) and what is the contribution of the active oscillator device, the xtal itself and the following buffers. Another idea that came on my mind was using digital oscillator (square wave, cmos) and then filtering for sine output, if this makes sense for a low PN point of view. Is there any way to measure the close-in PN of oscillators with an amateur setup?
