HYPRES Inc., a developer of superconducting microelectronics (SME) technology, has successfully tested fabricated integrated circuits with a critical current density of 20 kiloamps per square centimeter. This major milestone puts HYPRES one step closer to its goal, as it builds the first all-digital transceiver (ADT) for wireless communications, capable of operation in clock speeds of more than 80 GHz . The ADT is being created for the Department of Defense.
