Procurement Notes
Verify that the specific suffix 'N' denotes the non-screened variant as per manufacturer documentation. Confirm compliance with MIL-DTL-M3933 standards for your application. Check RoHS status, as this component may not be compliant. Ensure SMA connector gender matches system requirements before ordering.
Selection Notes
Select this model when a fixed 7.5 dB attenuation is required up to 18 GHz. Consider the 2W power rating for thermal management. Verify if screened or non-screened versions are needed for EMI protection. Compare against other M3933/25 variants for different attenuation values.
Part Context
This part belongs to the M3933/25 series of connectorized attenuators. It is produced under the Midwest Microwave brand within Cinch Connectivity Solutions. The series offers various attenuation levels while maintaining consistent SMA interface and military-grade construction standards.
Replacement Considerations
Direct substitutes include other manufacturers producing MIL-DTL-M3933/25-73 equivalents. Verify electrical parameters such as attenuation tolerance and VSWR match exactly. Ensure mechanical dimensions and SMA connector compatibility remain unchanged.
