Temperature Compensated Radio-Frequency Harmonic Bulk Acoustic Resonators
Abstract
In this paper, we present a new approach for the fabrication and use of thinned single crystal films for the development of radio-frequency temperature compensated devices. We particularly focus on High-overtone bulk acoustic resonators (HBAR) for oscillator stabilization, taking advantage of the very high quality factors achievable with such devices. We obtained a good agreement between simulation and experiments. This paper shows the possibility to obtain device which is intrinsically low sensitive to thermal effects, and even allowing a second order compensation thanks to the Quartz thermal stability.
