Cryogenic Attenuators

Amphenol XMA Cryogenic Attenuators are linear, passive transmission line components designed to lower the input power in a matched system. These attenuators offer a power range of 0.5W to 2W, a frequency range of 18GHz to 40GHz, and up to 30 coupling options. Amphenol XMA Cryogenic Attenuators feature state-of-the-art thermalization methods, tight tolerancing, and numerous shapes and materials to fit various applications.
