DARPA’s Terahertz Electronics

Parent Category: Rocktabs Archive

Researchers under DARPA’s Terahertz Electronics (THz) program have designed and demonstrated a 0.85 Terahertz power amplifier using a micromachined

vacuum tube—a world’s first. The achievement comes from DARPA-funded researchers at Northrop Grumman Electronic Systems, who built the 1 centimeter-wide traveling wave vacuum tube. The vacuum tube power amplifier is only one achievement of the broader THz program, which seeks to develop a variety of breakthrough component and integration technologies necessary to one day build complex THz circuits for communications and sensing.
