M3933/25-75S

Overview

The M3933/25-75S is a military-grade RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It operates within a frequency range of 0 Hz to 18 GHz and provides an attenuation value of 8.5 dB. The component features SMA connectors in an in-line module configuration with a 50 Ohm impedance. It supports a maximum power dissipation of 2W and complies with MIL-DTL-M3933 standards.

Feature Summary

• Complies with MIL-DTL-M3933 military specifications for reliability
• Provides precise 8.5 dB signal attenuation across wide bandwidth
• Utilizes robust SMA connector interface for secure integration

Applications

• Military communication systems requiring strict regulatory compliance
• Test and measurement equipment calibration setups
• Aerospace electronic subsystems demanding high-frequency stability

Procurement Notes

Verify the suffix 'S' against official documentation to confirm specific screening or material variations compared to the 'N' variant. Ensure procurement channels source directly from authorized distributors to guarantee authenticity. Confirm that the required MIL-DTL-M3933 compliance meets your project's specific qualification standards before finalizing orders.

Selection Notes

Select this model when an 8.5 dB fixed attenuation is required at frequencies up to 18 GHz. The SMA in-line format suits applications needing compact integration without PCB mounting. Consider the 2W power rating to ensure thermal management aligns with system operational limits under continuous wave conditions.

Part Context

This component belongs to the M3933/25 series, which defines standardized RF attenuators for defense and aerospace sectors. The series ensures consistent performance characteristics across various attenuation values while maintaining strict dimensional and electrical tolerances defined by military standards.

Replacement Considerations

The M3933/25-75N serves as a direct functional substitute within the same series. Verify if the 'N' suffix denotes non-screened or alternative material construction compared to the 'S' variant. Cross-reference mechanical drawings to ensure pinout and housing compatibility during replacement.
