Title: Michiyuki Nakazawa: Innovator in Surface Acoustic Wave Technology
Introduction: Michiyuki Nakazawa is a prominent inventor based in Tokyo, Japan, recognized for his significant contributions to the field of surface acoustic wave (SAW) technology. With a total of five patents to his name, Nakazawa has developed innovative solutions that enhance the performance and functionality of acoustic wave filters.
Latest Patents: Among his most recent patents, Nakazawa has formulated a "Longitudinally Coupled Resonator-Type Surface Acoustic Wave Filter." This invention discloses a surface acoustic wave filter composed of two or more interdigital transducers (IDTs) arranged in the propagation direction of the surface acoustic wave. Notably, the design incorporates pairs of IDTs that are acoustically coupled but feature different numbers of paired electrode fingers. Moreover, the pitch between neighboring electrode fingers varies, resulting in no primary pitch area within the IDTs.
Another remarkable patent is the "Surface Acoustic Wave Filter and Resonator Utilizing a Branch Electrode with an Electrically Opened End." This design entails a SAW filter that consists of an IDT on a piezo-electric substrate, with interdigital electrodes arranged to propagate surface acoustic waves. The branch electrodes extend orthogonally from the interdigital electrodes, allowing for substantial flexibility in application, such as in longitudinally coupled multi-mode filters or ladder-type filters, showcasing high Q values and low insertion loss.
