M3933/25-48N

Overview

The M3933/25-48N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a nominal attenuation of 22 dB with a 50 Ohm impedance. The device operates within a frequency range of 0 Hz to 12.4 GHz and supports a maximum power dissipation of 2 Watts. It utilizes SMA single-row module connectors for in-line integration. The component complies with MIL-DTL-M3933 standards, indicating its qualification for military-grade applications.

Feature Summary

• Complies with MIL-DTL-M3933 specifications for military-grade reliability
• Provides fixed 22 dB attenuation across a wide DC to 12.4 GHz bandwidth
• Features robust SMA single-row module construction for secure in-line mounting

Applications

• Military electronic systems requiring precise signal level control
• Aerospace communication equipment operating at microwave frequencies
• Test and measurement instrumentation for RF signal conditioning

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure compliance with current MIL-DTL-M3933 standards. Confirm that the SMA connector gender and mating requirements align with system interface specifications. Check for RoHS status as military components may not meet standard environmental directives. Validate supply chain authenticity through authorized distributors to prevent counterfeit components.

Selection Notes

Select this component when a fixed 22 dB attenuation is required within a 0 Hz to 12.4 GHz operational range. Ensure the system impedance matches the 50 Ohm specification to minimize reflections. Verify that the 2 Watt power handling capacity exceeds the maximum expected signal power in the application. Consider the SMA module form factor for compatibility with existing chassis or cable assemblies.

Part Context

This attenuator belongs to the M3933/25 series, which consists of fixed-value RF attenuators designed for high-reliability environments. The series is characterized by its compliance with military standards and use of SMA connectors. These components are engineered for consistent performance in demanding conditions, supporting various attenuation values within the specified frequency limits.

Replacement Considerations

Compatible substitutes include other M3933/25 series variants from Cinch Connectivity Solutions Midwest Microwave, such as M3933/25-62N or M3933/25-75N, provided the attenuation value meets system requirements. Cross-reference technical datasheets to confirm identical frequency ranges, power ratings, and connector types before substitution.
