2082-6040-00-CRYO

Overview

The Amphenol XMA 2082-6040-00-CRYO is a cryogenic RF attenuator designed for linear, passive transmission line applications. It provides a fixed attenuation of 0 dB within a frequency range of 0 Hz to 18 GHz. The component operates at a power rating of 2W with a characteristic impedance of 50 Ohms. It utilizes SMA male-to-female in-line module connectors and is constructed for compatibility with cryogenic environments.

Feature Summary

• Designed as a linear, passive transmission line component specifically engineered for cryogenic temperature operation.
• Provides zero decibel signal attenuation while maintaining system impedance matching across the specified frequency band.

Applications

• Cryogenic radio frequency test and measurement systems
• Low-noise amplifier characterization in cold environments
• Superconducting quantum interference device (SQUID) signal conditioning

Procurement Notes

Verify that the specific CRYO suffix designation confirms the component's suitability for your required operating temperature range. Ensure that the SMA interface gender configuration matches your existing cable assembly or fixture requirements. Confirm that the 2W power handling capability aligns with your maximum input signal levels to prevent component damage during operation.

Selection Notes

Select this model when a non-attenuating, matched transmission path is required within a cryogenic setup. The 0 dB value indicates it functions primarily as a robust interconnect rather than a signal reducer. Consider the SMA connector type for standard RF integration. Verify that the 18 GHz upper frequency limit meets your application's bandwidth needs without introducing significant insertion loss variations.

Part Context

This part belongs to the Amphenol XMA family of cryogenic attenuators, which are specialized linear passive components. Unlike standard room-temperature attenuators, these units are built to maintain electrical stability under extreme cold conditions. The series includes various attenuation values, but this specific model offers a 0 dB configuration for direct signal passage.

Replacement Considerations

Direct substitutes must also be designated for cryogenic use with identical SMA interfaces and 0 dB attenuation. Generic room-temperature attenuators are not suitable replacements due to potential material contraction and performance drift at low temperatures. Verify that any alternative part maintains the same 50 Ohm impedance and 2W power rating specifications.
