Title: The Innovations of Phillip Welsh
Introduction
Phillip Welsh is an accomplished inventor based in Maitland, FL (US). He has made significant contributions to the field of technology, particularly in the development of advanced filter packages. His work focuses on enhancing the performance and reliability of surface acoustic wave (SAW) filters.
Latest Patents
Phillip Welsh holds a patent for a "Wafer-level surface acoustic wave filter package with temperature-compensating characteristics." This innovative SAW filter is fabricated at a wafer level to provide desirable temperature characteristics. The design includes a piezoelectric substrate bonded to a carrier substrate, with the coefficient of thermal expansion of the carrier substrate being less than that of the piezoelectric substrate. Interdigital transducers are formed on the piezoelectric substrate, creating a SAW composite die structure. A cap substrate, which has a coefficient of thermal expansion similar to that of the carrier substrate, is bonded to the SAW composite die structure to enclose the interdigital transducers. Plated vias form signal pad interconnects to the input and output pads of the interdigital transducer, while a sealing pad on the surface of the piezoelectric substrate bonds the SAW composite die structure to the cap substrate. Phillip Welsh has 1 patent to his name.
