Procurement Notes

Verify availability status directly with authorized distributors as supply may be restricted. Confirm that the specific cryogenic variant matches your thermal requirements. Ensure compatibility with existing SMA interfaces. Check for updated manufacturing revisions. Validate compliance with project-specific environmental standards before procurement.

Selection Notes

Select this model when fixed 10dB attenuation is required at frequencies up to 18 GHz under cryogenic conditions. Compare power handling capabilities against system input levels. Consider physical dimensions for integration within confined cold stages. Evaluate connector gender configurations for proper cable mating. Assess long-term stability needs for sensitive measurement applications.

Part Context

This component belongs to Amphenol XMA's specialized line of cryogenic test equipment.
