4880-5522-20-CRYO

Attenuators Overview

The Amphenol XMA 4880-5522-20-CRYO is a precision RF attenuator designed for high-frequency applications. It features a 2.92mm female-to-female inline module interface, providing a fixed attenuation value of 20 dB. The component operates across a frequency range from DC to 40 GHz and supports a maximum power handling capacity of 1 Watt. With a nominal impedance of 50 Ohms, this device is engineered for stability in demanding environments, including cryogenic conditions.

Attenuators Feature Summary

• Engineered for operation in extreme low-temperature environments such as dilution refrigerators and cryostats
• Provides stable 20 dB attenuation across a wide bandwidth extending to 40 GHz
• Utilizes a robust 2.92mm female-to-female coaxial connector interface

Attenuators Applications

• Calibration of test equipment in quantum computing systems
• Signal conditioning within dilution refrigerator setups
• RF measurements in cryogenic research laboratories

Attenuators Procurement Notes

Verify the specific cryogenic rating requirements against your system's thermal environment before procurement. Confirm that the 2.92mm interface compatibility matches your existing measurement chain. Ensure the 1W power limit is sufficient for your signal levels. Check current availability status as supply may be restricted for specialized components.

Attenuators Selection Notes

Select this model when precise attenuation is required at frequencies up to 40 GHz in cryogenic settings. The 2.92mm interface offers superior performance over standard SMA connectors at these frequencies. Consider the 1W power handling capability relative to your input signals. This part is suitable for applications requiring minimal phase shift and high repeatability in cold environments.

Attenuators Part Context

This component belongs to the Amphenol XMA series of RF attenuators specifically designed for challenging environmental conditions. The product line focuses on maintaining electrical performance under thermal stress. The 4880-5522-20-CRYO variant addresses the need for reliable signal control in advanced scientific instrumentation where standard components might fail or drift.

Attenuators Replacement Considerations

Direct substitutes include other cryogenic-rated 2.92mm attenuators with identical 20 dB attenuation and 40 GHz bandwidth. Verify mechanical dimensions and connector gender compatibility when considering alternatives. Ensure replacement parts meet the same power handling specifications.
