About Low Noise Factory

Low Noise Factory (LNF) designs and produces the world’s best low noise microwave amplifiers. These amplifiers are used near absolute zero –cryogenic– temperatures for space exploration, quantum computing, radio astronomy, and for various ground-breaking scientific endeavors where extreme sensitivity is paramount. Our amplifiers help receive signals from the most distant man-made object from Earth, the Voyager 1 space probe, help read quantum states in the fastest quantum computers. Low Noise Factory’s state-of-the-art amplifiers are far ahead of the competition. We invest heavily in research and collaborate closely with academic and scientific communities to keep advancing our technology further and further. Our success is the result of passion for science and precision, advanced by devotion and curiosity. As explorers on the technological frontier, our aim is to keep making the impossible possible. We do everything from basic research to product development, production and testing. In our 1500 sqm facility in Gothenburg we have a state-of-the-art laboratory with electronics assembly all the way to high frequency cryogenic testing. In addition, we have access to advanced cleanrooms where we develop and produce our semiconductor circuits. LNF has 24 employees with a background from 14 different countries.
