2682-6460-06-CRYO

Overview

The Amphenol XMA 2682-6460-06-CRYO is a precision SMA male-to-female attenuator designed for cryogenic environments. It provides a fixed attenuation of 6dB with a frequency range of DC to 26.5 GHz. The component operates at 50 Ohms impedance and handles up to 2W of power. Constructed from stainless steel, it features a hexagonal round body suitable for extreme temperature applications.

Feature Summary

• Designed specifically for operation in extreme cryogenic conditions including dilution refrigerators
• Provides precise signal reduction via fixed 6dB attenuation value
• Supports wide-spectrum high-frequency performance up to 26.5 GHz

Applications

• Calibration of measurement systems in dilution refrigerators
• Signal conditioning within quantum computing test setups
• Integration into cryostats requiring stable RF attenuation

Procurement Notes

Verify availability through authorized distributors as supply may be restricted in certain regions. Confirm the specific CRYO suffix indicates cryogenic suitability rather than standard room-temperature operation. Ensure compatibility with SMA interfaces and 50 Ohm system requirements before ordering.

Selection Notes

Select this model when fixed 6dB attenuation is required in ultra-low temperature environments. Verify that the SMA interface matches the system connectors. Ensure the 2W power rating meets the application's signal levels. Consider the stainless steel construction for durability in vacuum or cryogenic chambers.

Part Context

This component belongs to Amphenol XMA's specialized line of interconnect attenuators engineered for cryogenic use. It complements other calibration kits like the FF-TFL-KIT-CRYO by providing discrete attenuation stages. The product series focuses on maintaining electrical stability under thermal stress typical of quantum research hardware.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must verify interface compatibility and attenuation values when considering alternatives. Direct replacement requires matching the SMA-m/f configuration and 26.5 GHz frequency limit.
