| Summary: | With the advent of new technologies, the requirements for the sources of reference
vibrations are becoming more stringent. They must be compact, quickly reach
frequency, operate in a wide temperature range and have a small relative frequency
drift in the operating temperature range.
Changes in ambient temperature are the most destabilizing factor for the oscillator
output frequency. Ensuring frequency stability over a wide temperature range
is a pressing task.
Thermal compensation allows increasing frequency stability over a wide range
of operating temperatures. This is achieved by compensating for the effect of the
destabilizing factor on the generator so that the frequency drift tends to zero as
the temperature changes. Temperature-compensated quartz oscillators are highly
stable and have a short readiness time. However, to create generators with a
frequency stability of ± 0,1 ppm, imported components are required, which makes
their production difficult in modern conditions.
A technological chain is created at the JSC «LIT-PHONON», which allows
producing a quartz resonator using only Russian components. The goal is to use
these resonators in temperature-compensated oscillators with frequency stability
of ± 0,1 ppm. However, the analysis showed that the resonators have problems with
frequency drift over time during operation at a maximum operating temperature of
+ 85 ºС. Additional adjustment of generators during operation is required. It is also
revealed that some Russian components are not ideally suited to the developed
technological process, which may negatively affect the yield of suitable products.
The measuring setup also has an error of ± 0,5 ppm, which does not allow an
accurate assessment of the frequency stability of the resonators. |
