4882-6140-06-CRYO

Attenuators Overview

The Amphenol XMA 4882-6140-06-CRYO is a precision connectorized attenuator designed for high-frequency applications. It features a fixed attenuation value of 6dB and operates within a frequency range of 0 Hz to 40 GHz. The component utilizes a 2.92mm male-to-female interface configuration, ensuring compatibility with standard RF test setups. It supports a maximum power handling capacity of 1 Watt and maintains a characteristic impedance of 50 Ohms. The unit is constructed as an in-line module with a physical length of 22.09 mm, suitable for integration into cryogenic environments.

Attenuators Feature Summary

• Designed specifically for extreme low-temperature environments including dilution refrigerators and cryostats
• Provides stable fixed attenuation performance across ultra-wideband frequencies up to 40 GHz
• Utilizes robust 2.92mm interconnect technology for reliable signal integrity in critical measurement systems

Attenuators Applications

• Calibration and testing within dilution refrigerator systems
• Signal conditioning in cryostat-based quantum computing experiments
• High-frequency RF measurements in extreme cold laboratory environments

Attenuators Procurement Notes

Verify the specific suffix CRYO to confirm cryogenic qualification, as standard variants may lack thermal stability data. Ensure the manufacturer documentation explicitly lists operation below 4 Kelvin if required by your system design. Cross-reference the 2.92mm gender configuration (male/female) against your existing fixture requirements to prevent mating issues. Confirm that the 1W power rating aligns with your peak signal levels under all operating conditions.

Attenuators Selection Notes

Select this model when fixed 6dB attenuation is required at frequencies extending to 40 GHz in sub-zero conditions. The 2.92mm interface offers superior performance over SMA or K-type connectors at these frequencies. Consider the 50 Ohm impedance match for standard RF infrastructure. Evaluate the 1W power limit against your source output to avoid damage. This part is intended for specialized cryogenic research rather than general commercial RF use.

Attenuators Part Context

This component belongs to Amphenol XMA's dedicated cryogenic calibration and interconnect series. These parts are engineered to maintain electrical parameters during thermal cycling from room temperature down to millikelvin ranges. The product line addresses the unique challenges of signal transmission in quantum information processing hardware where standard components fail due to thermal contraction or parameter drift.
