Spectrum Control Cryo Attenuators

Quantum computing has the power to change our understanding of the world. But to function properly, quantum computers depend on cryogenic refrigeration systems that may require thousands of coaxial attenuators.

Spectrum Control’s newest attenuators, tested to 4mK, support these leading edge tools. Just one example of the quality, reliability and innovation of our coaxial attenuators.


About Cryo Attenuators

Quantum computing and cryogenic applications are cool, but you can also find APITech coaxial attenuators in satellites, radar systems, in the newest mobile testing equipment, helping service providers deliver coverage, and performing under some of the harshest conditions.

APITech offers a wide selection of fixed microwave attenuators with frequency ranges from DC to 50GHz, and power handling to 1,000 watts. APITech designs, tests, and manufactures its attenuators and works with you to optimize performance for your specific application. APITech will also work with you to provide attenuators based on connector type, form factor requirements, and the materials best suited for your application. Plus, for any environmental concerns.

APITech’s high reliability attenuators are specifically designed to meet or exceed the requirements imposed by government, military and industry.


APITech also offer chip attenuators. Made from a proprietary thin-film technology, they maintain resistance down to near absolute zero.
