Cryogenic RF Coaxial Attenuators
Quantum Computing Attenuators
Spectrum Control cryogenic RF attenuators are designed for low thermal noise in quantum computing and cryogenic systems. Available in SMA and coaxial configurations, they deliver ultra-low VSWR, superior flatness, minimal self-heating, and reliable performance at temperatures approaching absolute zero, with frequency coverage up to 40 GHz.
Low Thermal Noise Cryogenic Attenuators
Spectrum Control cryogenic attenuators provide low VSWR approaching 1.15:1 and attenuation values up to 30 dB in a 50-ohm system.
SMA Cryogenic Attenuators for High-Frequency Performance
Spectrum Control SMA cryogenic attenuators direct resistive heat to the cold plate, reducing thermal noise. Gold-plated beryllium copper conductors and a beryllium oxide substrate maintain electrical contact through thermal contraction and expansion.

SMA Cryogenic Attenuators for High-Frequency Performance
Spectrum Control’s cryogenic RF attenuators are low thermal noise attenuators designed for quantum computing and cryogenic systems, available in SMA and coaxial configurations. Spectrum Control designs ultra-low VSWR (1.1:1) cryogenic coaxial attenuators that deliver best-in-class VSWR performance. These ultra-low VSWR, superior-flatness attenuators provide continuous, reliable operation at temperatures approaching absolute zero. Engineered to minimize self-heating, which can introduce additional thermal noise. Spectrum Control’s cryogenic attenuators support frequency operation up to 40 GHz.
