2082-6043-20-CRYO

Overview

The Amphenol XMA 2082-6043-20-CRYO is a cryogenic attenuator designed for operation in extreme low-temperature environments. It provides a fixed attenuation of 20dB with a frequency range extending from 0 Hz to 18 GHz. The component features SMA connectors and maintains a 50 Ohm impedance. It is rated for a power handling capacity of 2W, ensuring stable performance in matched systems requiring precise signal reduction under cryogenic conditions.

Feature Summary

• Linear passive transmission line design specifically engineered for cryogenic temperature stability
• Fixed 20dB attenuation value maintained across the operational frequency spectrum
• SMA connectorized inline module configuration for direct system integration

Applications

• Cryogenic test and measurement setups
• Low-temperature RF signal conditioning
• Embedded systems operating in extreme cold environments

Procurement Notes

Verify specific cryogenic performance curves and thermal contraction specifications against your application's temperature profile before procurement. Confirm that the SMA interface compatibility matches your existing fixture requirements. Ensure the 2W power rating aligns with your system's maximum input levels at the target operating temperature to prevent component damage or performance deviation.

Selection Notes

Select this component when standard attenuators fail to maintain accuracy at cryogenic temperatures. The 20dB fixed value suits applications requiring significant signal reduction. Consider the SMA interface for standard laboratory connections. Evaluate the 2W power limit against peak signal levels. This model is distinct from non-cryogenic variants due to its specialized material composition for thermal stability.

Part Context

This part belongs to the Amphenol XMA Cryogenic Attenuators series, which are linear, passive components designed to lower input power in matched systems. Unlike standard room-temperature attenuators, these units utilize materials and construction methods that preserve electrical characteristics during exposure to extreme cold, making them essential for specialized scientific and industrial testing environments.

Replacement Considerations

Direct substitutes must match the 20dB attenuation, 18 GHz frequency range, and SMA interface. Verify that any replacement also supports cryogenic operation if required. Non-cryogenic equivalents may exhibit parameter drift at low temperatures. Consult manufacturer documentation for cross-reference lists to ensure functional equivalence without compromising thermal performance.
