2082-6051C-20-CRYO

Overview

The Amphenol XMA 2082-6051C-20-CRYO is a cryogenic RF attenuator designed for extreme low-temperature environments. It provides a fixed attenuation value of 20dB with a frequency range extending from 0 Hz to 18 GHz. The component operates at a nominal impedance of 50 Ohms and supports a power handling capacity of 1 Watt. It utilizes SMA male-to-female inline connectors, ensuring compatibility with standard RF test setups while maintaining performance under cryogenic conditions.

Feature Summary

• Engineered specifically for operation in extreme cryogenic environments such as dilution refrigerators and cryostats
• Utilizes advanced thermalization methods to maintain signal integrity at low temperatures
• Features tight tolerancing and specialized materials to ensure reliability in harsh conditions

Applications

• Calibration of RF measurement systems within dilution refrigerators
• Signal conditioning in quantum computing experimental setups
• Testing components inside high-vacuum cryostats

Procurement Notes

Verify the specific suffix requirements for your application, as cryogenic variants often differ from standard room-temperature models. Confirm that the SMA interface matches your existing cabling infrastructure. Ensure the 1W power rating aligns with your system's maximum output levels. Check for RoHS3 compliance if required by your procurement standards. Validate availability through authorized distributors due to potential supply constraints on specialized cryogenic components.

Selection Notes

Select this model when fixed 20dB attenuation is required in sub-kelvin environments. Compare against other 2082 series variants for different attenuation values or power ratings. Consider the 18 GHz bandwidth limit for high-frequency applications. Evaluate the SMA connector type against alternative interfaces like 3.5mm or 2.92mm if higher frequency performance is needed. Ensure the physical form factor fits within your cryostat's limited space constraints.

Part Context

This component belongs to the Amphenol XMA cryogenic attenuator family, which specializes in RF components for quantum research and low-temperature physics. These devices are distinct from standard commercial attenuators due to their specialized thermal management and material selection. The product line addresses the unique challenges of maintaining electrical stability and mechanical integrity during thermal cycling between room temperature and millikelvin ranges.

Replacement Considerations

Direct substitutes include other Amphenol XMA cryogenic attenuators with matching 20dB attenuation and SMA interfaces, such as the 2082-6051C-03-CRYO for different attenuation needs. Verify that any replacement maintains the same 1W power handling and 18 GHz frequency range. Cross-reference datasheets to ensure identical connector gender and polarity specifications.
