Latest Patents

Kawatsu's latest patents reflect a cutting-edge approach to mechanical filter design. The first patent introduces a mechanical filter that features at least one longitudinal vibration mode vibrator, which includes a piezoelectric ceramic plate. This plate is equipped with an electrode pair on its top and bottom surfaces, and it is polarized in its thickness direction to create at least two polarized regions with differing polarization directions.

His second patent showcases another mechanical filter that comprises at least two longitudinal mode vibrators. Each of these vibrators consists of a piezoelectric ceramic member with constant modulus alloy members installed separately on its top and bottom surfaces. Notably, these alloy members are designed to have an opposite frequency-temperature characteristic to that of the piezoelectric ceramic member, coordinating their centers with that of the ceramic. This design aims to suppress higher order spurious vibration modes within the mechanical filter itself.
