SCHAUMBURG -- Sparton Corp. has been issued two patents by the United States Patent and Trademark Office. One patent is for an invention that protects electronic circuits and devices from radiated electromagnetic fields by using nickel phosphorus or nickel chromium material embedded within the layers of a printed circuit board to function as a filter. The second patent is for an invention that improves switching mode power amplifiers. The improved design eliminates undesirable effects of finite transition time, provides higher efficiency, and is scalable. The amplifier also provides other performance advantages relative to conventional switching mode power amplifier designs.
"Sparton has an extensive and growing library of patents across a range of technologies," said Jim Lackemacher, group vice president of the Engineered Components and Products Segment. "These two patents are important additions to that library as we move forward in a marketplace that is dynamic and increasingly more competitive. Sparton's growing technological expertise allows us to provide the most innovative products to our customers."
