2082-6340-06-CRYO

Overview

The Amphenol XMA 2082-6340-06-CRYO is an RF attenuator designed for cryogenic environments. It features a SMA male-to-female connector interface and operates within a frequency range of 0 Hz to 18 GHz. The component provides a fixed attenuation value of 6 dB with a 50 Ohms impedance. It supports a maximum power handling capacity of 2 Watts. The device utilizes a round, stainless steel housing with a length of 0.76 inches.

Feature Summary

• Designed specifically for extreme low-temperature applications including dilution refrigerators and cryostats
• Provides stable 6 dB attenuation across a wide DC to 18 GHz bandwidth
• Constructed with stainless steel housing for durability in harsh environments

Applications

• Calibration of measurement systems in dilution refrigerators
• Signal conditioning in quantum computing test setups
• Integration into cryostat-based microwave measurement chains

Procurement Notes

Verify the specific CRYO suffix requirement against your system's thermal design specifications. Confirm that the SMA interface compatibility matches your existing cabling infrastructure. Ensure the 2W power rating aligns with your signal levels to prevent damage. Check manufacturer documentation for detailed mechanical drawings and thermal performance data relevant to your operating temperature range before finalizing procurement.

Selection Notes

Select this model when fixed 6 dB attenuation is required in sub-zero environments. Compare against standard room-temperature variants if cryogenic operation is not necessary. Consider the SMA interface constraints and ensure the 0.76-inch form factor fits within your available space. Evaluate the 2W power limit against peak signal strengths to maintain operational safety margins during testing.

Part Context

This component belongs to the Amphenol XMA series of connectorized attenuators specialized for cryogenic use. It complements other models in the family by offering specific attenuation values tailored for quantum and low-temperature research applications. The product line focuses on maintaining electrical performance stability under extreme thermal conditions.

Replacement Considerations

The 2082-6340-06 is listed as a parametric equivalent or substitute option. Verify interface compatibility and attenuation tolerance before swapping. Ensure the replacement part retains the CRYO designation for thermal suitability.
