The Double Oven OCXO series is the standard in
terms of stability. It is based on the HC27 crystal
(glass package) and the HC46 crystal (metal cold
weld package) we are manufacturing.
The heater-system controls the thermal gradient
on the crystal blank to better than 0.01° C in the
standard operating temperature range.
Therefore we guaranty a thermal stability of
2.10
-10
from 0 to 70° C, and ageing rates as low as
to 1.10
-9
per year.
Features
Ultra high stability
Ultra low ageing
Low phase noise
