“…The STS of the oscillators utilizing the DHR technology was limited by significant influence on their frequency of fluctuations of the thermal stresses induced in the plate by variation of the power in the film heaters caused mainly by the noise in the thermo-control system [5].…”

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.
