The author considers the performance of tactical BVA quartz resonators, specifically their measured frequency stability. Data are presented demonstrating the resonators' ability to survive harsh environmental conditions. Test results suggest that an

During the past two decades very important advances have been accomplished in reducing the phase modulation (PM) noise in state-of-the-art bulk wave quartz crystal oscillator. Various limitations have been significantly reduced, especially those rela

Acceleration sensitivity of a quartz resonator is usually attributed to the design of the unit. BVA technologies have largely participated to g-sensitivity reduction since 1977. At that time it was claimed that symmetry of the unit structure was fund

Performance requirements from pressure and temperature sensors especially for use in oil fields are very demanding. Several years of effort have been devoted to the development of a dual-mode thickness-shear quartz pressure sensor to meet such requir

A cylindrical oven whose axis is the axis of the 10 MHz quartz resonator (in HC 40 can) is studied. Thermal flux is canalized on its axis at a place where the thermistor is located. Thermal exchanges include conduction and radiation effects, reduced,

44th Annual Symposium on Frequency Control.
A BVA quartz resonator which has been developed for use in severe environments is discussed. More than one hundred units have been produced and tested in France and in the US. The resonator is a 10 MHz, 3/sup rd/ overtone SC cut crystal. The unit fit

Phase noise reduction is still an important goal in ultra stable oscillator design. As a contribution to understanding of phase noise generation, two identified mechanisms are analysed. The first one involves nonlinearities. It may be, for example, t

The goal of this study is to set up an improved model of the frequency stability behavior of the oscillating loop. A computer aided analysis is performed in which the transfer functions of the loop can be entirely described. This allows to predict ph

BVA technologies for piezoelectric resonators were introduced in the late 70s (1976, 1977, 1978). Since then, a lot of work dealing with BVA resonators has been done in our laboratory and also in several other laboratories including industry laborato
