Guinness World Records has recognized <b>DARPA</b>’s Terahertz
Electronics program for creating the fastest solid-state amplifier
integrated circuit ever measured. The 10-stage common-source MMIC
achieves 9 dB gain at 1.03 THz. Noise figure and output power have not
yet been measured.</div>
<div>
The MMIC was designed and fabricated by Northrop Grumman Corp. using 25
nm InP HEMTs as the active devices. Researchers used E-beam lithography
to define the gates on the MMIC, which was 18 µm thick and no bigger
than a grain of kosher salt, according to Bill Deal, manager of the
Terahertz Electronics program at Northrop Grumman.</div>
<div>
The previous high frequency record for a solid-state amplifier was 850
GHz, set in 2012 by Northrop Grumman, on the same DARPA program.</div>
<div>
The objective of the Terahertz Electronics program is to develop the
device and integration technologies to realize compact, high-performance
transceivers that operate above a THz. The program is funding the
development of InP HBT and HEMT transistor technologies as well as
low-loss interconnects to integrate multiple MMICs into compact
transmitter and receiver modules.</div>
<div>
“Terahertz circuits promise to open up new areas of research and
unforeseen applications in the sub-millimeter-wave spectrum, in addition
to bringing unprecedented performance to circuits operating at more
conventional frequencies,” said Dev Palmer, DARPA program manager. “This
breakthrough could lead to revolutionary technologies such as
high-resolution security imaging systems, improved collision-avoidance
radar, communications networks with many times the capacity of current
systems and spectrometers that could detect potentially dangerous
chemicals and explosives with much greater sensitivity.” </div></div>
