Abstract :
The authors discuss the design of TC-cut crystals for S-TCXOs that do not involve special means to reduce the temperature instability. With this object in view single-crystal, two-crystal and three-crystal TC-cut units have been developed and studied. In the temperature range of (-10 +55)°C the units display a frequency instability from several ppm for single crystal down to ±0.3 × 10-6 for three-crystal units. XOs using the developed resonators are described. Because of the excellent characteristics of the units the oscillators have a short-term stability and phase noise level close to those of miniature OCXO, while their size, consumed power, and warm-up time are the same as those of TCXOs
