• Quantum computing research infrastructure

Attenuators Procurement Notes

Verify the specific cryogenic rating and connector gender compatibility before integration. Confirm that the 1W power handling meets system requirements at operating temperatures. Ensure the 2.92mm interface matches existing test equipment. Check manufacturer documentation for thermal cycling specifications relevant to your specific application environment.

Attenuators Selection Notes

Select this component when a fixed 3dB attenuation is required in the 40 GHz range under cryogenic conditions. Compare against other Amphenol XMA cryogenic attenuators if different attenuation values or connector types are needed. Ensure the stainless steel construction aligns with magnetic and thermal constraints of the target assembly.

Attenuators Part Context

This model belongs to the Amphenol XMA cryogenic attenuator series, which includes various attenuation values and connector configurations. These components are passive linear transmission line devices intended to lower input power in matched systems. The series supports high-frequency measurements where standard components would fail due to temperature extremes.

Attenuators Replacement Considerations

Direct substitutes include other Amphenol XMA models within the same cryogenic family, such as the 4882-6240-00-CRYO, provided the attenuation value and connector type match the design requirements. Verify that any replacement maintains the 2.92mm interface and 40 GHz frequency capability.
