Abstract :
Among the crystals belonging to the langasite family, the langatate one (La3Ga5.5Ta0.5O14 also called LGT) seems the best candidate to substitute to the quartz crystal for frequency and time applications. Pairs of LGT crystal resonators prototypes working at 10 MHz have been measured on an advanced phase noise measurement system. The LGT crystal resonators noise has been measured according to various driving power values. Investigations on the amplitude-frequency effect with different LGT crystal resonators were done. Analysis and discussion of the results are presented as conclusions.
