4882-6040-00-CRYO

Attenuators Overview

The Amphenol XMA 4882-6040-00-CRYO is a cryogenic attenuator designed for extreme low-temperature environments. It features a 2.92mm male-to-female connector interface and operates from DC to 40 GHz. The component provides 0 dB attenuation with a 50 Ohm impedance. It supports a power rating of 0.5W (500 mW) and utilizes stainless steel construction in a round inline module format.

Attenuators Feature Summary

• Engineered specifically for operation within dilution refrigerators and cryostats
• Utilizes advanced thermalization methods to maintain performance at cryogenic temperatures
• Constructed with tight tolerancing and stainless steel materials for structural integrity

Attenuators Applications

• Dilution refrigerator systems
• Cryostat integration
• Quantum computing test setups

Attenuators Procurement Notes

Verify the specific suffix requirements for your application, as the CRYO designation indicates specialized cryogenic handling. Confirm that the 0.5W power rating aligns with your system's thermal load. Ensure the 2.92mm connector compatibility matches your existing interconnect infrastructure before procurement.

Attenuators Selection Notes

Select this component when standard attenuators fail under cryogenic conditions due to thermal stress or drift. The 0 dB value suggests its use for impedance matching or isolation rather than signal reduction. Consider the 40 GHz bandwidth limit for high-frequency quantum applications requiring minimal insertion loss impact.

Attenuators Part Context

This part belongs to the Amphenol XMA Cryogenic Attenuators series, which addresses the unique challenges of RF testing in ultra-low temperature environments. Unlike standard RF components, these are optimized for thermal management and mechanical stability during cooldown cycles.

Attenuators Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific cryogenic configuration. Alternative models may require re-evaluation of thermalization capabilities and connector type compatibility.
