M3933/16-03S

Overview

The M3933/16-03S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 10 dB with a 50 Ohm impedance. The device operates within a frequency range of 0 Hz to 18 GHz and supports a power rating of 2 W. It utilizes SMA connectors in an in-line module configuration. The component is designed for military applications, complying with MIL-DTL-M3933 standards.

Feature Summary

• Complies with MIL-DTL-M3933 military specifications for qualified parts list (QPL) performance.
• Features SMA connector interface for reliable high-frequency signal transmission.
• Constructed as a screened in-line module for robust environmental resistance.

Applications

• Military electronic systems requiring precise signal attenuation
• Aerospace communication equipment testing
• Harsh environment RF circuit protection

Procurement Notes

Verify that the specific order includes QPL screening and MIL-DTL-M3933 compliance documentation. Confirm the SMA connector gender matches system requirements. Ensure the 10 dB attenuation value aligns with design specifications. Check for RoHS non-compliance status if environmental regulations apply. Validate manufacturer authenticity through authorized distribution channels.

Selection Notes

Select this model when a 10 dB fixed attenuation is required at frequencies up to 18 GHz. Consider the 2 W power handling capability for signal levels within this limit. Choose the SMA interface for compatibility with existing connector infrastructure. Verify military qualification requirements against project specifications before procurement.

Part Context

This component belongs to the M3933/16 series of connectorized attenuators from Cinch Connectivity Solutions. The series offers various attenuation values while maintaining consistent SMA interfaces and military-grade construction. It serves as a specialized passive RF component for defense and aerospace sectors.

Replacement Considerations

Compatible substitutes include other M3933/16 series variants with different attenuation values, such as M3933/16-03N or M3933/16-13S, provided the attenuation difference is acceptable. Cross-reference MIL-DTL-M3933 equivalents from other qualified manufacturers if supply constraints exist.
