Attenuators Procurement Notes

Verify the specific revision level and lot traceability documentation prior to procurement. Ensure that the ordering suffix matches the required connector orientation and pinout specifications. Confirm compliance with current export control regulations and space qualification certificates are available from the manufacturer or authorized distributors.

Attenuators Selection Notes

Select this component when a fixed 1dB attenuation is required within the 18 GHz bandwidth. Consider the SMA interface compatibility with existing board layouts. Evaluate thermal management requirements based on the 2W power rating. Verify that the physical dimensions fit within the designated enclosure constraints for the target assembly.

Attenuators Part Context

This part belongs to the SQA-01 series of space-qualified attenuators from Midwest Microwave. The series offers various attenuation values while maintaining consistent electrical performance across the DC to 18 GHz range. These components are engineered for use in harsh environments where standard commercial parts would fail due to radiation or thermal stress.

Attenuators Replacement Considerations

Direct replacements must match the 1dB attenuation, SMA interface, and space-qualification status. Verify mechanical footprint compatibility. Cross-reference with other SQA-series variants if different attenuation values are acceptable.
