M3933/25-80N

Overview

The M3933/25-80N is a radio frequency military specification attenuator manufactured by Amphenol SV Microwave. It belongs to the SMA series and features a male-to-female connector configuration with a nominal impedance of 50 ohms. The component supports a maximum frequency of 18 GHz and operates within a temperature range of -65°C to +165°C. This specific model is classified as a nonscreened unit designed for high-frequency signal attenuation applications.

Feature Summary

• Provides RF signal attenuation in a compact SMA connectorized form factor
• Constructed for operation in extreme thermal environments up to +165°C
• Features a nonscreened design suitable for integration into various RF systems

Applications

• Military communication systems requiring precise signal level control
• Test and measurement equipment operating at frequencies up to 18 GHz
• Aerospace electronic assemblies demanding high-temperature reliability

Procurement Notes

Verify that the required attenuation value aligns with the specific M3933/25-80N designation, as this series includes multiple variants with different dB ratings. Confirm the nonscreened construction meets environmental shielding requirements for the target application. Ensure compatibility with standard SMA mating interfaces and validate power handling capabilities against system specifications before procurement.

Selection Notes

Select this component when an 18 GHz SMA attenuator is needed for military or aerospace applications. Consider the nonscreened variant if electromagnetic shielding is not critical or handled externally. Compare against screened versions like the M3933/25-xxS series if environmental protection is required. Verify the exact attenuation value matches the system design needs, as values vary across the M3933/25 family.
