Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and screening levels. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and compliance with military quality standards. Cross-reference the part number with current datasheets to validate availability and technical specifications prior to ordering.

Selection Notes

Select this component when a fixed 21.5 dB attenuation is required at frequencies up to 18 GHz. The SMA interface and 2W power handling capability make it suitable for standard RF applications. Consider the in-line module form factor for integration into existing connectorized assemblies. Verify environmental operating ranges and impedance matching requirements against system specifications before finalizing the design choice.

Part Context

This model belongs to the M3933 series, which encompasses various fixed attenuators designed for military and aerospace use. The series offers different attenuation values and frequency ranges while maintaining consistent mechanical interfaces. This specific variant addresses high-frequency applications requiring significant signal reduction within a compact SMA footprint.

Replacement Considerations

Compatible substitutes include other M3933 series variants such as M3933/16-xxS models with similar attenuation profiles. Verify that alternative parts match the 21.5 dB attenuation, 18 GHz frequency limit, and SMA connector gender. Ensure any replacement maintains the same power rating and impedance characteristics.
