Low-Noise Amplifier Can Detect Radiation Traces, Chalmers University of Technology Study

Researchers at Chalmers University of Technology in Sweden have demonstrated an integrated amplifier that offers new possibilities for detecting the faintest electromagnetic radiation. A fundamental property for the first microwave amplifier in the radio receiver is its noise figure, which is normally given in decibels (dB). A typical noise figure for low-noise amplifiers in mobile communication systems is tenths of a decibel.
