M3933/25-68S

Overview

The M3933/25-68S is a screened RF fixed attenuator manufactured by Amphenol SV Microwave. It utilizes SMA connectors with a male-to-female configuration and operates within a frequency range of DC to 18 GHz. The component provides a nominal attenuation of 5 dB at a 50 Ohm impedance level. It supports a maximum power rating of 2 Watts and is constructed with stainless steel materials for durability in demanding environments.

Feature Summary

• Screened construction for enhanced environmental protection
• Stainless steel housing for mechanical robustness
• SMA plug-to-jack interface design

Applications

• Military radio systems
• Avionics signal conditioning
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant required for your application, as non-screened versions may exist within the same series. Confirm that the SMA gender configuration matches your system interconnect requirements. Ensure the 2W power handling capacity is sufficient for your operational signal levels to prevent component damage or performance degradation during use.

Selection Notes

Select this model when a precise 5 dB attenuation value is needed within the 18 GHz bandwidth. The screened version is appropriate for applications requiring protection against external interference or harsh environmental conditions. Consider the physical size and mounting constraints of the in-line module format before integration into the assembly.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. The series includes various attenuation values and connector types designed for high-reliability applications. The M3933/25-68S specifically addresses the need for moderate attenuation in SMA-based microwave circuits operating up to 18 GHz.

Replacement Considerations

M3933/25-68N is a parameter-equivalent alternative within the same manufacturer's lineup. Verify compatibility regarding screening specifications and material composition when substituting.
