An engineer has integrated a non-reciprocal circulator and a full-duplex radio on a nanoscale silicon chip for the first time. This breakthrough technology needs only one antenna, thus enabling an even smaller overall system than one he developed last yea. It could revolutionize the field of telecommunications.
Krishnaswamy, director of the Columbia High-Speed and Mm-wave IC (CoSMIC) Lab said: “Our circulator is the first to be put on a silicon chip, and we get literally orders of magnitude better performance than prior work...
