New tool blocks high-frequency signal interference, aids 6G tech | The adjustable filter is designed to prevent signals from causing interference, even in higher-frequency bands. The quarter-sized filter will unlock the next generation of wireless communications.
Engineers at University of Pennsylvania School of Engineering and Applied Science created an innovative tool to block interference in the electromagnetic spectrum. The quarter-sized filter will unlock the next generation of wireless communications.
The electromagnetic spectrum is one of the modern world’s most valuable resources, yet only a minuscule fraction of it, primarily radio waves, representing less than one billionth of one percent, is suitable for wireless communication. “Right now we work from 600 MHz to 6 GHz,” explained Olsson, who is also the senior author of a new paper in Nature Communications that describes the filter. However, by integrating a novel circuit with extremely thin YIG films micromachined in the Singh Center for Nanotechnology, the new filter achieves significantly reduced power consumption and size.
