Abstract

The paper describes farther progress in the internally heated resonators (IHR) resulting is essential improvement of their frequency stability at remaining extremely small size, power consumption and warm-up time. There is also considered in the paper an effective solution of suppression of the B-mode in the oscillator circuitry based on novel "dynamic selection" method. Experimental study of the OCXOs built on new IHR design proved their excellent temperature stability along with high short-term stability, low aging and phase-noise level. Combined with extremely small size and power consumption it makes new OCXO an effective alternation to conventional OCXOs in a variety of applications.
