M3933/25-68S

Overview

The M3933/25-68S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 5 dB with a power rating of 2 W. The component operates within a frequency range of 0 Hz to 18 GHz and maintains a 50 Ohm impedance. It utilizes SMA connectors in an in-line module configuration. This part complies with MIL-DTL-M3933 standards, indicating suitability for military-grade applications.

Feature Summary

• Complies with MIL-DTL-M3933 specifications for defense electronics
• Provides fixed 5 dB attenuation across DC to 18 GHz bandwidth
• Features robust SMA in-line module construction

Applications

• Military communication systems requiring precise signal reduction
• Aerospace test and measurement instrumentation
• Defense electronic equipment signal conditioning

Procurement Notes

Verify the suffix 'S' indicates screened QPL status against official manufacturer documentation. Confirm compliance with MIL-DTL-M3933 requirements for your specific application environment. Ensure SMA connector gender matches system interface needs. Check RoHS status as military parts may differ from commercial standards.

Selection Notes

Select this model when a fixed 5 dB attenuation is required up to 18 GHz. The SMA interface suits standard RF testing setups. Consider the 2 W power handling capability for high-power signal paths. Verify temperature ratings align with operational extremes. Compare against other M3933/25 variants for different attenuation values.

Part Context

This component belongs to the M3933/25 series of fixed attenuators. It shares the same form factor and interface as other models in the family but differs in attenuation value. The series supports various dB levels while maintaining consistent electrical performance characteristics across the frequency range.

Replacement Considerations

M3933/25-68N serves as a direct substitute with identical electrical specifications. Verify screening level differences between N and S suffixes. Other M3933/25 models offer alternative attenuation values.
