M3933/25-29S

Overview

The M3933/25-29S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It features SMA male-to-female connectors and provides a nominal attenuation of 3 dB. The device operates within a frequency range of 0 Hz to 12.4 GHz with a 50 Ohm impedance. It has a power rating of 2 W and functions between -55°C and +165°C. This component complies with MIL-DTL-M3933 standards.

Feature Summary

• Complies with MIL-DTL-M3933 military specifications for reliability
• Provides precise 3 dB signal attenuation in an inline module design
• Operates reliably across extreme temperature ranges up to 165°C

Applications

• Military communication systems requiring screened components
• Aerospace radar signal processing circuits
• High-frequency test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'S' indicates screened qualification status per manufacturer documentation. Confirm that the SMA connector gender configuration matches system requirements. Ensure environmental ratings align with operational thermal constraints. Cross-reference part numbers against official distributor catalogs to avoid counterfeit components. Validate compliance with relevant export control classifications before procurement.

Selection Notes

Select this model when a fixed 3 dB attenuation is required for frequencies up to 12.4 GHz. Consider the wide operating temperature range for harsh environment applications. Verify compatibility with existing SMA interfaces in the signal chain. Evaluate power handling capabilities against peak signal levels. Compare against other MIL-DTL-M3933 variants for specific attenuation values.

Part Context

This component belongs to the M3933/25 series of connectorized attenuators from Cinch Connectivity Solutions. These devices are designed for high-reliability applications meeting military standards. The series offers various attenuation values with consistent SMA interface geometry. Manufacturing follows strict quality controls for aerospace and defense sectors.

Replacement Considerations

M3933/25-28N serves as a functional substitute offering identical 3 dB attenuation and SMA connectivity within the same military specification framework.
