Cryogenic Attenuators

Withwave’s Cryogenic RF attenuators have been specifically designed to provide precise attenuation
values over the frequency range of DC to 18 GHz at extreme low cryogenic temperatures.
They offer excellent performance, making them ideal for quantum electrodynamics devices including quantum
computing and other RF applications at cryogenic temperatures.

Attenuators are thoroughly evaluated by using Withwave’s 4 K cryogenic measurement system to ensure optimal reliability in cryogenic environments.

Features
