Abstract: A switchable filter may include a first acoustic resonator including first electrodes, and a first resonant layer between the first electrodes and having electrostrictive material. The switchable filter may further include a second acoustic resonator including second electrodes, and a second resonant layer between the second electrodes and having electrostrictive material. The second acoustic resonator may be acoustically coupled with the first acoustic resonator. At least one of the first electrodes and at least one of the second electrodes may be arranged between the first resonant layer and the second resonant layer. The electrostrictive material may adjust a resonance and a filter switching of the first and second acoustic resonators as a function of a control voltage applied to terminals of the first and second acoustic resonators. Two electrodes from one of the first electrodes and the second electrodes may be filter input electrodes. Two electrodes from one of the first electrodes and the second electrodes may be filter output electrodes.

Abstract: A coupled Lamb wave resonator filter includes first and second Lamb wave resonators. The first Lamb wave resonator includes a first resonant layer, and first and second electrodes on opposite sides of the first resonant layer. The second Lamb wave resonator includes a second resonant layer, and third and fourth electrodes on opposite sides of the second resonant layer. One of the sides of the first resonant layer belongs to a plane parallel to a plane corresponding to one of the sides of the second resonant layer. Both planes pass through the third and fourth electrodes of the second Lamb wave resonator. A periodic lattice acoustically couples the first and second resonant layers.

Abstract: A Micro Electro Mechanical Systems resonance device includes a substrate, and an input electrode, connected to an alternating current source having an input frequency. The device also includes an output electrode, and at least one anchoring structure, connected to the substrate. The device further includes a vibratile structure connected to an anchoring structure by at least one junction, having a natural acoustic resonant frequency. The vibration under the effect of the input electrode, when it is powered, generates, on the output electrode, an alternating current wherein the output frequency is equal to the natural frequency. The vibratile structure and/or the anchoring structure includes a periodic structure. The periodic structure includes at least first and second zones different from each other, and corresponding respectively to first and second acoustic propagation properties.
