2082-6042-10-CRYO

Overview

The Amphenol XMA 2082-6042-10-CRYO is an RF attenuator designed for cryogenic environments. It provides a fixed attenuation of 10dB with a frequency range of 0 Hz to 18 GHz. The component features a 50 Ohm impedance and handles up to 2W of power. It utilizes SMA male-to-female connectors in an inline module configuration.

Feature Summary

• Designed specifically for extreme low-temperature applications including dilution refrigerators and cryostats
• Provides stable signal attenuation across a wide bandwidth from DC to 18 GHz
• Constructed as a robust inline module with standard SMA interface connections

Applications

• Calibration of measurement systems within dilution refrigerators
• Signal conditioning in quantum computing research setups
• Testing components inside high-vacuum cryostats

Procurement Notes

Verify the specific suffix CRYO to ensure cryogenic compatibility, as standard variants may lack necessary material specifications for low-temperature operation. Confirm that the 2W power rating aligns with your system's thermal constraints. Check availability status as specialized cryogenic components often have limited supply chains or longer lead times compared to standard RF parts.

Selection Notes

Select this model when fixed 10dB attenuation is required in sub-Kelvin environments. Ensure the SMA interface matches your existing cabling infrastructure. Consider the 18 GHz upper frequency limit to verify it covers your operational bandwidth. Compare against other models in the 2082 series if different attenuation values or power ratings are needed for your specific application.

Part Context

This part belongs to the Amphenol XMA cryogenic attenuator family, which includes various attenuation levels such as 0dB, 6dB, and 20dB. These components share similar physical dimensions and connector types but differ in internal resistive elements to achieve specific loss values. The series is engineered to maintain performance stability under thermal cycling conditions typical of advanced physics experiments.

Replacement Considerations

Direct substitutes include other Amphenol XMA models like 2082-6041-06 for 6dB or 2082-6502-20 for 20dB attenuation, provided they meet the same cryogenic requirements. Verify that any replacement maintains the 18 GHz frequency range and 50 Ohm impedance to ensure circuit continuity without re-characterization.
