2082-6040-03-CRYO

Overview

The Amphenol XMA 2082-6040-03-CRYO is a cryogenic RF attenuator designed for operation in extreme low-temperature environments. It provides a fixed attenuation value of 3dB with a frequency range extending from 0 Hz to 18 GHz. The component features a 50 Ohm impedance and handles a power rating of 2W. It utilizes SMA connectors in an inline module configuration, ensuring reliable signal management in specialized applications requiring stable performance under cryogenic conditions.

Feature Summary

• Designed specifically for cryogenic operational environments to maintain signal integrity at extremely low temperatures
• Provides precise fixed attenuation of 3dB across a wide bandwidth from DC to 18 GHz
• Constructed as a linear passive transmission line component for matched impedance signal reduction

Applications

• Cryogenic test and measurement systems
• Low-temperature RF circuit signal conditioning
• Specialized aerospace or scientific instrumentation requiring stable attenuation at cryogenic temperatures

Procurement Notes

Verify the specific suffix 'CRYO' confirms the cryogenic variant when sourcing replacements. Ensure the application environment strictly supports the thermal requirements of this component. Confirm connector gender and polarity match the system design before procurement. Check manufacturer documentation for detailed handling instructions related to thermal cycling.

Selection Notes

Select this model when a fixed 3dB attenuation is required within the 0-18 GHz range for cryogenic applications. Consider the 2W power rating against expected signal levels. Verify that SMA interface compatibility exists with existing system components. Evaluate if the inline module form factor fits the physical constraints of the assembly.

Part Context

This component belongs to the Amphenol XMA family of connectorized attenuators. It is part of a series of linear, passive transmission line devices engineered for interconnect applications. The product line focuses on providing reliable RF signal control in demanding environments, including those involving extreme temperature variations.

Replacement Considerations

Consider the 2082-6040-03 as a non-cryogenic alternative if thermal conditions do not require specialized cooling. Verify that any substitute maintains the 3dB attenuation value and 50 Ohm impedance. Ensure the replacement supports the same SMA connector type and frequency range up to 18 GHz.
