Cryogenic Solutions

Amphenol XMA Cryogenic Solutions include terminations and attenuators that feature state-of-the-art thermalization methods. The cryogenic terminations are capped to ensure the signal stops where and when it is needed. The terminations offer maximum frequency ratings of 18GHz, 26.5GHz, and 40GHz and a power range of 0.5W to 2W. The cryogenic attenuators are linear, passive transmission line components designed to lower the input power in a matched system by a predetermined amount. Amphenol XMA Cryogenic Solutions are available in male and female options.
