4882-6040-03-CRYO

Attenuators Overview

The Amphenol XMA 4882-6040-03-CRYO is a connectorized RF attenuator designed for cryogenic environments. It features a 2.92mm male-to-female interface and provides a fixed attenuation of 3dB. The component operates within a frequency range of 0 Hz to 40 GHz with a 50 Ohm impedance. It supports a maximum power handling of 500mW (0.5W). The physical length is specified as 22.09 mm, and the unit weight is 7 g.

Attenuators Feature Summary

• Engineered specifically for operation in extreme low-temperature conditions such as dilution refrigerators and cryostats.
• Provides precise signal attenuation using a robust 2.92mm interconnect system suitable for high-frequency applications.

Attenuators Applications

• Calibration of test equipment in cryogenic setups
• Signal conditioning in quantum computing research systems
• Integration into dilution refrigerator measurement chains

Attenuators Procurement Notes

Verify that the specific CRYO suffix designation aligns with your thermal management requirements. Confirm that the 500mW power rating is sufficient for your operational signal levels at 40 GHz. Ensure mechanical compatibility with existing 2.92mm fixtures before integration.

Attenuators Selection Notes

Select this model when fixed 3dB attenuation is required in sub-zero environments. Compare against standard room-temperature variants if cryogenic performance is not necessary. Verify that the 2.92mm gender configuration matches your system's male or female port requirements.

Attenuators Part Context

This component belongs to the Amphenol XMA line of connectorized attenuators. It is part of a specialized family designed for test and measurement equipment operating in harsh thermal conditions. The product serves as a critical passive element for maintaining signal integrity in advanced scientific instrumentation.

Attenuators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the 2.92mm interface, 3dB value, and cryogenic qualification status.
