Title
(EN) SURFACE ACOUSTIC WAVE RESONATOR MOUNTING WITH LOW ACCELERATION SENSITIVITY
(FR) MONTAGE DE RÉSONATEUR À ONDES ACOUSTIQUES DE SURFACE À FAIBLE SENSIBILITÉ AUX ACCÉLÉRATIONS
Abstract
(EN)
A device, comprising a substrate (140) having opposing first and second surfaces, a first surface acoustic wave resonator (120) disposed on the first surface of the substrate, a second surface acoustic wave resonator (130) disposed on the second surface of the substrate, a first adhesive layer (150) sandwiched between the first surface acoustic wave resonator (120) and the substrate (140), and a second adhesive layer (160) sandwiched between the second surface acoustic wave resonator (130) and the substrate (140). This provides a resonator with low acceleration sensitivity. The adhesive layers may have a portion removed to define a cutout region. A tuning mechanism coupled to the first surface acoustic wave resonator (120) may enable tuning of resonator acceleration sensitivity post assembly in an oscillator.

La présente invention concerne un dispositif qui comporte un substrat (140) présentant des première et seconde surfaces opposées, un premier résonateur à ondes acoustiques de surface (120) disposé sur la première surface du substrat, un second résonateur à ondes acoustiques de surface (130) disposé sur la seconde surface du substrat, une première couche adhésive (150) placée en sandwich entre le premier résonateur à ondes acoustiques de surface (120) et le substrat (140) et une seconde couche adhésive (160) placée en sandwich entre le second résonateur à ondes acoustiques de surface (130) et le substrat (140). Ce dispositif permet d'obtenir un résonateur à faible sensibilité aux accélérations. Une partie des couches adhésives peut être éliminée pour délimiter une zone de découpe. Un mécanisme d'accord couplé au premier résonateur à ondes acoustiques de surface (120) peut permettre d'accorder la sensibilité aux accélérations du résonateur, après assemblage, dans un oscillateur.
