Researchers take big step to making terahertz chips commercially viable

Even before millimeter wave spectrum is deployed on a mainstream basis, researchers are starting to cast their eyes even higher, to the so-called terahertz spectrum (in cellular terms, from 100 GHz to 540 GHz). Technologies to make these very high bands usable by mobile devices are the foundation of the initial R&D projects referred to as ‘6G’. The latest development comes from the University of California, Irvine (UCI), whose Nanoscale Communication Integrated Circuits lab has demonstrated a wireless transceiver chip which can send signals in frequencies above 100 GHz, claiming lower cost and power consumption than existing designs. These are, of course, the two major challenges facing chips in any new spectrum band, especially at very high frequency. Now that…
