Latest Patents

Kishimoto's latest patents include a piezoelectric device and a method for producing the same. This device ensures resistance to molding without an increase in costs. It features an elemental substrate with a piezoelectric element and a conductive pattern electrically connected to the piezoelectric element. Insulating members are disposed on the elemental substrate, surrounding the piezoelectric element while leaving a space around it. These insulating members contain an internal conductor connected to the conductive pattern, which extends apart from the elemental substrate. The internal conductor has expanded portions that intersect the wiring direction or a detour portion that deviates from it. This design allows the expanded portions or detour portion to cross the boundary of a sealed space formed around the piezoelectric element.

Another notable patent is the surface acoustic wave duplexer. This device serves as a branching filter that reduces the deterioration of insertion loss and improves isolation characteristics. The surface acoustic wave filter includes first ends of a first acoustic wave filter, which has a relatively low passband, and a second acoustic wave filter with a relatively high passband. These filters are connected to a first common terminal linked to an antenna. Among the plurality of parallel-arm resonators and series-arm resonators, the resonator of the first surface acoustic wave filter closest to the first common terminal is a parallel-arm resonator. The capacitance of this resonator is less than half of the capacitance of the other parallel-arm resonators.
