Attenuators Procurement Notes

Verify the specific datasheet version and qualification status directly with the manufacturer or authorized distributors before procurement. Ensure that the SMA connector gender and mounting requirements match the system design. Confirm RoHS compliance and export control classification (EAR99) for regulatory adherence. Check current availability as lead times may vary due to specialized manufacturing processes.

Attenuators Selection Notes

Select this component when a fixed 2dB attenuation is required within the 0 Hz to 18 GHz bandwidth. It is appropriate for designs demanding space-grade reliability and radiation tolerance. Consider the 2W power rating and SMA interface compatibility with existing circuitry. Evaluate thermal management needs based on the specified power dissipation limits.

Attenuators Part Context

This part belongs to the QPS Attenuators series, specifically designed for qualified parts for space applications. It shares the SQA-01 series designation with other variants offering different attenuation values such as 1dB or 6dB, all maintaining similar frequency and power specifications.

Attenuators Replacement Considerations

Direct substitutes include other SQA-01 series models like SQA-0180-01-SMA-02 or SQA-0181-02-SMA-02 if attenuation differences are acceptable. Verify mechanical dimensions and connector orientation for interchangeability.
