Wow - imagine the antenna for 1THz!  Thanks for the forward.

Guinness World Records has recognized DARPA’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.
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.
The previous high frequency record for a solid-state amplifier was 850 
GHz, set in 2012 by Northrop Grumman, on the same DARPA program.
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.
“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.”
