NoiseTech Microwaves Ltd. is based in Calgary, Alberta Canada. It was originally co-founded by Leo Belostotski and Michael Himmelfarb to make noise-parameter measurement accessible even to smaller team and startups who cannot afford other expensive options. As the result we developed impedance generators used for ultra-fast and accurate noise parameter measurements. It was soon realized that our approach is also applicable to measuring noise parameters of cryogenic circuits, which led NoiseTech to building industry-first line of products for measuring cryogenic noise parameters. Switches were also developed to speed up calibration and reduce the number of times connections have to be manipulated. The frequency range has also evolved from that of standard wireless systems (0.1 to 6GHz) to 20GHz and above for quantum computing/sensing applications.
