Future 6G wireless networks will consist of a multitude of small radio cells that need to be connected by broadband communication links. An international team of researchers (Germany, USA – industry) has developed a novel concept for low-cost terahertz receivers that consist of a Schottky barrier diode that offers large bandwidth and that is used as an envelope detector to recover the amplitude of the terahertz signal. To overcome the problem of losing the time-dependent phase of the terahertz wave that is usually lost during rectification, they use digital signal processing techniques in combination with a special class of data signals. The terahertz receiver stands out due to its technical simplicity and lends itself to cost-efficient mass production…read more. TECHNICAL ARTICLE
