  • Filtering circuit with coupled acoustic resonators
    Patent number: 8188811
    Abstract: A filter with coupled resonator having a substrate; an acoustic mirror intended to support acoustic resonators, and to isolate these resonators from the substrate; a first structure with an upper resonator and a lower resonator coupled to one another through at least one layer of acoustic coupling; a second structure with an upper resonator and a lower resonator coupled to one another through at least one layer of acoustic coupling; the lower resonators of the first and second structure having the same electrodes. The first and second structures are connected via a fifth resonator for which electrodes and the piezoelectric layer of the lower resonators are of the first and second structure.
    Type: Grant

  • Lamb wave resonator
    Patent number: 7868517
    Abstract: A Lamb wave resonator includes a piezoelectric layer, and a first electrode against a first face of the piezoelectric layer. The first electrode includes fingers and a contact arm, with each finger including a first side in contact with the contact arm and two other sides parallel to one another. Portions of the piezoelectric layer are at least partially etched between the two fingers to form a recess. The fingers are spaced apart from one another by a distance W calculated according to the following equation: W = n ยท va lateral f , with ? ? n ? N where, valateral is an acoustic propagation speed of Lamb waves, n is an order of a resonance mode of the Lamb waves, f is a resonance frequency of the Lamb wave resonator.
