Columbia engineers invent breakthrough millimeter-wave circulator IC


October 6, 2017

Researchers at Columbia Engineering and The University of Texas at Austin continue to break new ground in developing magnet-free non-reciprocal components in modern semiconductor processes. They have built the first magnet-free non-reciprocal circulator on a silicon chip that operates at millimeter-wave frequencies, enabling circulators to be built in conventional semiconductor chips and operate at millimeter-wave frequencies, enabling full-duplex or two-way wireless.
