• Features SMA single-row module connector interfaces
• Designed for operation up to 18 GHz frequency range
• Screened Qualified Products List (QPL) classification

Applications

• Military electronic systems requiring qualified components
• Aerospace communication equipment
• Test and measurement instrumentation
• Harsh environment RF signal conditioning

Procurement Notes

Verify that the specific part number matches the required attenuation value and frequency range for the application. Confirm compliance with MIL-DTL-M3933 standards if military qualification is mandatory. Check for RoHS non-compliance status as indicated in official documentation. Ensure SMA connector gender and mating requirements align with system design constraints before procurement.

Selection Notes

Select this component when a 10 dB fixed attenuation is required at 50 Ohms impedance. Consider the 2W power handling capability for signal levels. Verify the 18 GHz upper frequency limit meets system bandwidth needs. Ensure compatibility with SMA connector types used in the assembly. Review environmental operating temperature ranges against deployment conditions.

Part Context

This model belongs to the M3933/16 series of fixed attenuators from Cinch Connectivity Solutions Midwest Microwave. The series offers various attenuation values while maintaining consistent 50 Ohm impedance and SMA connectivity. These components are engineered for defense and aerospace applications demanding strict adherence to military performance standards and long-term reliability in demanding operational environments.

Replacement Considerations

M3933/16-25S serves as a screened variant within the same family. Other M3933/16 models provide different attenuation values but share similar form factors. Verify exact electrical parameters and connector genders when substituting. Cross-reference MIL-DTL-M3933 compliance for equivalent military grade performance.
