Title: Molecular Clock - 231.060983 GHz reference oscillators almost atomic grade
Post by: RoGeorge on July 17, 2018, 01:30:02 pm

If these will be put in mobile phones, we all will soon have almost atomic grade reference oscillators with a cost in the range of single digit mW and $.  :-+

Maybe.  If they can make it cheap and tiny and low power and reliable.

200+ GHz semiconductors aren't cheap today.  And this isn't especially better stability than good OCXOs -- it's better than anything else low power that you can fit in your phone, I suppose.

To be fair though, it's a neat paper.
