A team of Penn Engineers, led by Associate Professor Troy Olsson, PhD, Associate Professor in Electrical and Systems Engineering (ESE) at Penn Engineering, have developed an adjustable high frequency filter that prevents signal interference in wireless communications and data transfers.
The filter, made from a material called yttrium iron garnet (YIG), can tune across a broad frequency range and is significantly smaller and more power-efficient than previous models. This breakthrough could facilitate the use of the new Frequency Range 3 (FR3) band for 6G networks and beyond, potentially revolutionizing wireless communications.
