Submission + - Record High Frequency Achieved
eldavojohn writes: "Researchers at UCLA Henry Samueli School of Engineering and Applied Science managed to push our control of frequencies to another level when they hit a submillimeter 324 gigahertz frequency. As any signal geek out there might tell you, this is a non-trivial task. From the article, "With traditional 90-nanometer CMOS circuit approaches, it is virtually impossible to generate usable submillimeter signals with a frequency higher than about 190 GHz. That's because conventional oscillator circuits are nonlinear systems in which increases in frequency are accompanied by a corresponding loss in gain or efficiency and an increase in noise, making them unsuitable for practical applications." The article also talks about the surprising applications this new technology may evolve into including seeing through clothing. While one might dream up more perverse situations to use this in, it is unsurprising that this is instead targeting military/security applications for seeing hidden explosive devices and/or weapons."
