Attenuators Procurement Notes

Verify the specific revision status and lot traceability documentation upon order confirmation. Ensure that the SMA connector gender and mating interface align with the system schematic. Confirm that the thermal management strategy accommodates the 2 W power dissipation within the operational temperature range specified in the official datasheet.

Attenuators Selection Notes

Select this component when a fixed 3 dB reduction is required in broadband RF paths up to 18 GHz. It is suitable for applications demanding space-grade reliability and low total mass loss. Compare against other SQA series values if different attenuation levels are needed while maintaining the same form factor and qualification class.

Attenuators Part Context

This part belongs to the SQA-01 series of space-qualified attenuators from Cinch Connectivity Solutions. The series offers various attenuation values (1 dB to 20 dB) with consistent mechanical and electrical performance profiles. All units undergo stringent screening to meet space mission requirements.

Attenuators Replacement Considerations

Direct substitutes include other SQA-0180-03 variants with compatible connector options. Verify pinout and mounting dimensions before substitution. Cross-reference with ATT-0276-03-SMA-02 for non-space applications requiring similar electrical specs.
