2682-6460-30-CRYO

Overview

The Amphenol XMA 2682-6460-30-CRYO is an inline RF attenuator module designed for cryogenic environments. It provides a fixed attenuation of 30dB with a frequency range from DC to 26.5 GHz. The component operates at a power rating of 2W and maintains a characteristic impedance of 50 Ohms. It utilizes SMA male-to-female connectors for interconnection.

Feature Summary

• Designed specifically for extreme low-temperature applications including dilution refrigerators and cryostats
• Provides stable signal attenuation across a wide microwave spectrum up to 26.5 GHz
• Features robust SMA connector interface for reliable in-line integration

Applications

• Dilution refrigerator calibration setups
• Cryostat signal path management
• Quantum computing measurement chains

Procurement Notes

Verify regional availability as distribution may be restricted in certain locations. Confirm the specific CRYO suffix designation ensures compatibility with your thermal environment requirements. Check current manufacturer status as this is listed as a new product from Amphenol XMA. Ensure ordering documentation matches the exact part number to avoid generic SMA attenuator substitutions that lack cryogenic ratings.

Selection Notes

Select this model when fixed 30dB attenuation is required in sub-kelvin environments. The 2W power handling suits standard low-power quantum measurements. Verify that SMA interfaces match existing cabling infrastructure. Consider the 26.5 GHz upper limit against your specific signal bandwidth needs. This component is distinct from standard room-temperature attenuators due to its specialized thermal design.

Part Context

This component belongs to the Amphenol XMA cryogenic calibration kit series, which includes TRL kits and other test equipment tailored for quantum hardware testing. It complements other specialized interconnects like the 4882-6240-00-CRYO attenuator. The product line focuses on maintaining electrical performance under extreme cold conditions where standard components fail.

Replacement Considerations

No public confirmed substitute part numbers are available. Generic SMA attenuators do not meet the cryogenic operational specifications. Any replacement must be verified by Amphenol XMA for thermal compatibility.
