M3933/25-38N

Overview

The M3933/25-38N is a radio frequency military specification connector manufactured by Amphenol SV Microwave. It functions as an SMA male to female inline attenuator with a nominal attenuation of 12 dB and a 50 Ohm impedance. The component operates within a frequency range up to 18 GHz and supports a power rating of 2 W. Designed for rugged environments, it withstands operating temperatures from -65°C to +165°C. This non-screened variant is packaged in bulk and conforms to MIL-Spec standards.

Feature Summary

• Provides fixed signal attenuation via SMA male-to-female inline configuration
• Engineered for high-temperature stability up to +165°C
• Constructed for reliable performance in demanding RF applications

Applications

• Military communication systems requiring precise signal reduction
• Test and measurement equipment operating at microwave frequencies
• Aerospace electronic assemblies needing robust RF components

Procurement Notes

Verify the specific suffix 'N' confirms the non-screened construction when sourcing replacements. Confirm that the 12 dB attenuation value matches the system design requirements exactly. Ensure the SMA gender configuration aligns with existing cabling infrastructure. Check for any updated environmental compliance certifications required for the procurement destination.

Selection Notes

Select this model when a fixed 12 dB loss is necessary within an 18 GHz bandwidth. Consider the non-screened design if shielding is provided elsewhere in the assembly. Evaluate the 2 W power handling against peak signal levels. Compare temperature ratings against the operational environment to ensure reliability under thermal stress conditions.

Part Context

This part belongs to the M3933 series of RF connectors, which are designed to meet strict military specifications. The series includes various attenuation values and screening options. The M3933/25-38N specifically addresses applications requiring moderate signal reduction without electromagnetic shielding integration.

Replacement Considerations

M3933/25-38S is the screened equivalent version. Verify that the absence of shielding in the N variant does not compromise system integrity compared to the S variant.
