Latest Patents

One of Niwa's latest patents is titled "Acoustic resonators with reduced loss characteristics and methods of manufacturing same." This invention involves an acoustic resonator designed to prevent a radio frequency (RF) signal from being coupled to a cap substrate. The electronic device features a first substrate made of piezoelectric material, which supports an electronic circuit that includes a film bulk acoustic resonator. The second substrate, made of low-resistivity material, is positioned opposite the first substrate, creating a cavity that houses the electronic circuit. A thin film of high-resistivity material is applied to the bottom surface of the second substrate to mitigate RF signal coupling.

Another significant patent by Niwa is related to "Saw-based electronic elements and filter devices." This invention provides electronic elements and filter devices that prevent the deterioration of propagation characteristics caused by electromagnetic coupling. In this example, an electronic filter is designed with an element substrate that includes a plurality of surface acoustic wave (SAW) resonators. The filter also features a sealing substrate that defines a cavity, ensuring that the circuit is well-protected and connected to a ground potential.
