2682-6460-20-CRYO

Overview

The Amphenol XMA 2682-6460-20-CRYO is a cryogenic RF attenuator designed for extreme low-temperature environments. It provides a fixed attenuation of 20dB with a frequency range of DC to 26.5 GHz. The component features SMA male-to-female connectors and supports a power handling capacity of 2W at 50 Ohms impedance. Constructed as an in-line module, it is specifically engineered for use in dilution refrigerators and cryostats where standard components may fail.

Feature Summary

• Engineered for operation in extreme cryogenic conditions including dilution refrigerators
• Provides stable signal attenuation across a wide microwave frequency spectrum
• Utilizes robust SMA interconnects for reliable high-frequency performance

Applications

• Dilution refrigerator calibration systems
• Cryostat signal path management
• Quantum computing test setups
• Low-temperature RF measurement chains

Procurement Notes

Verify regional availability as distribution is restricted in certain areas. Confirm the specific cryogenic rating matches your system requirements. Check for updated datasheets regarding thermal cycling limits. Ensure SMA connector compatibility with existing cabling infrastructure before ordering.

Selection Notes

Select this model when fixed 20dB attenuation is required below 26.5 GHz in cryogenic settings. Compare against other values like 30dB if higher loss is needed. Ensure the 2W power rating suits your signal levels. Verify SMA interface matches your test equipment ports.

Part Context

This part belongs to Amphenol XMA's specialized cryogenic attenuator series. These components are distinct from standard room-temperature attenuators due to their material selection and construction methods optimized for thermal contraction. They serve critical roles in maintaining signal integrity within superconducting quantum circuits.

Replacement Considerations

Direct substitutes include the 2682-6460-30-CRYO for 30dB attenuation or the 4882-6240-20-CRYO for 2.92mm interfaces. Ensure any replacement maintains the same SMA configuration and cryogenic design specifications.
