Cryogenic RF Coaxial Attenuators
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.

Low Thermal Noise Cryogenic Attenuators
Spectrum Control cryogenic attenuators offer exceptional low VSWR approaching 1.15:1, with attenuation values up to 30 dB in a 50-ohm impedance system.
SMA Cryogenic Attenuators for High-Frequency Performance
Effective thermalization is essential for achieving near-absolute-zero temperatures. Spectrum Control attenuators provide a controlled thermal path that directs resistive heat to the cold plate rather than through the coaxial line, preventing unwanted thermal interference with sensitive components such as processors.
Constructed with gold-plated beryllium copper conductors and a beryllium oxide substrate, Spectrum Control cryogenic attenuators accommodate thermal contraction and expansion without losing electrical contact or introducing microphonic effects and excess thermal noise that could degrade performance.
