Chilled Electronics Race Ahead

摘要

An advanced microelectronics technology may allow future communications equipment to receive and process multiple high frequency waveforms easily. Relying on superconducting processors in a sealed refrigerated container, the system translates analog radio signals directly to digital information, preventing the data and efficiency losses found in semiconductor-based applications. Unconstrained by performance-limiting issues such as thermal interference, the frigid superconducting chips permit prototype devices to receive, sample and transmit gigahertz-range signals across much of the military's spectrum.
