Title: The Innovative Journey of Roger William Whatmore
Introduction
Roger William Whatmore, hailing from Milton Keynes, Great Britain, is a distinguished inventor known for his significant contributions to the field of acoustic resonators. With a remarkable portfolio of 16 patents, Whatmore has established himself as a leading figure in innovation, particularly in the design and application of film bulk acoustic resonator (FBAR) filters.
Latest Patents
Among his latest patents, Whatmore has developed groundbreaking technologies related to film bulk acoustic resonator filters. One noteworthy invention is a ladder-type FBAR filter that consists of two series FBARs and two parallel FBARs. Each resonator is designed with a top electrode, a bottom electrode, and a piezoelectric layer in between. This configuration allows for efficient signal transmission through a coplanar waveguide transmission line, connecting the top electrodes to associated circuitry while maintaining a common bottom electrode.
Additionally, Whatmore's innovative work on multiple thin film bulk acoustic resonators configured in series and parallel within a coplanar waveguide line structure has resulted in a compact ladder filter design. These resonators are strategically placed over an opening in a substrate and linked to circuitry via transmission lines, minimizing the area of the filter. The integration of the ladder filter within the coplanar transmission line structure simplifies fabrication by eliminating the need for wire bonds, thus enhancing production efficiency.
