Penn Engineers have developed a revolutionary quarter-sized adjustable filter to prevent interference in wireless communications, addressing issues faced by companies like LightSquared. The filter uses a unique material called yttrium iron garnet (YIG) to achieve continuous frequency tuning across a broad band, making it suitable for the new FR3 band for 6G or Next G networks. This filter is compact, low-power, and potentially game-changing in the wireless communications industry, with the potential to replace the numerous filters found in current devices. The filter will be presented at the 2024 IEEE Microwave Symposium, showcasing its innovative design and capabilities.
