Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm connector gender orientation and attenuation tolerance. Ensure that the screened finish requirement aligns with project specifications. Confirm compatibility with existing SMA interfaces before procurement. Check current availability status as lead times may vary for military-grade components.

Selection Notes

Select this model when a fixed 20 dB reduction is required in an 18 GHz SMA environment. Consider the 2 Watt power handling capability for system integration. Evaluate the operating temperature range against environmental conditions. Compare against other M3933 series variants if different attenuation values or connector configurations are needed.

Part Context

This component belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. The series includes various models with different attenuation levels and connector types. The M3933/25-88S specifically utilizes the SMA interface standard. It is categorized under RF MIL Spec Connectors and Attenuators.

Replacement Considerations

M3933/25-XXS generic series parts may offer similar functionality but require verification of specific attenuation values. Cross-reference with other manufacturers' 20 dB SMA attenuators rated for 18 GHz. Ensure mechanical and electrical parameters match exactly before substitution.
