NoiseTech Microwaves is pleased to announce the release of its first two product lines: impedance generators and cryogenic impedance generators. NoiseTech’s impedance generators are accurate, compact, fast, and inexpensive replacements to mechanical impedance tuners. These impedance generators are used for measuring noise parameters in the frequency range from 0.1GHz to 6GHz. The cryogenic impedance generator works at cryogenic temperatures. Other frequencies available upon request.
