M3933/25-05N

Overview

The M3933/25-05N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 5dB with a frequency range of 0 Hz to 2 GHz. The component operates at a maximum power rating of 2W and features a 50 Ohm impedance. It utilizes SMA connectors in an in-line module configuration. This part complies with the MIL-DTL-M3933 military specification.

Feature Summary

• Complies with MIL-DTL-M3933 military specifications for rugged performance
• Provides precise 5dB signal attenuation within the DC to 2 GHz band
• Features robust SMA in-line module construction for reliable interconnection

Applications

• Military electronic systems requiring qualified RF components
• Aerospace communication equipment testing and integration
• Defense radar and navigation signal conditioning circuits

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm exact electrical tolerances and connector gender, as variations exist within the M3933/25 series. Ensure compliance with project-specific material requirements, noting that this component may not meet RoHS standards. Confirm availability through authorized distributors or direct manufacturer channels due to potential supply chain constraints associated with military-grade parts.

Selection Notes

Select this model when a fixed 5dB attenuation is required up to 2 GHz in a compact in-line format. It is suitable for applications demanding MIL-DTL-M3933 qualification. Compare against other series members like M3933/25-62N for higher frequency needs or different attenuation values. Ensure system impedance matches the 50 Ohm specification and power handling requirements do not exceed 2W.

Part Context

This component belongs to the M3933/25 family of fixed attenuators from Cinch Connectivity Solutions Midwest Microwave. The series offers various attenuation values and frequency ranges, all sharing a common SMA in-line module form factor. These parts are designed for high-reliability environments, distinguishing them from commercial-grade alternatives through their adherence to strict military manufacturing standards.

Replacement Considerations

Direct substitutes include other M3933/25 series variants such as M3933/25-04N (4dB) or M3933/25-11S (11dB) if attenuation values differ. Verify mechanical compatibility and electrical parameters before substitution. Cross-reference with manufacturer cross-reference guides for equivalent parts from other qualified suppliers.
