WOW!​ Extraordinarily Low Phase Noise OCXO: -173 dBc/Hz at 1 KHz offset

30 Oct 2019

"Amazing!" and "WOW!" are some of the comments engineers made when I recently showed them this plot of phase noise vs frequency. It's not often you get that reaction from engineers. Here's why their reactions are justified.

In a radar system, lower phase noise translates to better receiver sensitivity. That means smaller targets can be picked up. That means the velocity of a target can be estimated more accurately from the returned radar pulse. That means ground clutter is reduced.

So when engineers see the -173 dBc/Hz phase noise at 1 KHz offset in the new 100 MHz Oven Controlled Crystal Oscillator (OCXO) reference module from NEL Frequency Controls, they can imagine the improvement in their radar system's performance if they were to use it in their design. That low of a phase noise is a big deal - I haven't seen it lower anywhere else.

Communication systems that use up-conversion or down-conversion similarly benefit from extraordinarily low phase noise.


I am the sales representative for NEL Frequency Controls in New England and New York. If you want a copy of the model 1942A preliminary data sheet of this breakthrough OCXO, please contact me here or call/text me at 978-337-8535.
