Abstract

This paper devoted to some aspects of OCXO application in an output stage of atomic frequency standard. The specific requirements that the OCXO must meet are excellent short term frequency stability and good total operational stability during very long life time. Also, we consider the low power consumption of the OCXO as a very important feature particularly for autonomous and Space applications. The main target of this project was a significant improvement of short term stability of basic OCXO designed with Internally Heated Quartz Resonator (IHQR).
