M3933/25-70S

Overview

The M3933/25-70S is a screened RF attenuator manufactured by Amphenol SV Microwave. It features SMA male to female connectors and operates within a frequency range of 0 Hz to 18 GHz. The component provides a nominal attenuation of 6 dB at a 50 Ohm impedance. It supports a power rating of 2W and functions reliably between -65°C and +165°C.

Feature Summary

• Screened construction for military specification reliability
• SMA male to female inline module configuration
• Wide operational temperature range up to +165°C

Applications

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

Procurement Notes

Verify the specific suffix 'S' indicates screened status per manufacturer documentation. Confirm that the 6 dB attenuation value matches system requirements. Ensure SMA connector gender orientation aligns with interface design. Validate environmental ratings against operational constraints.

Selection Notes

Select this model when an 18 GHz SMA attenuator with 6 dB loss is required. Consider the 2W power handling capability for signal levels. Verify compatibility with existing SMA interfaces. Check if screened packaging meets project specifications.

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. The M3933/25 variant specifically utilizes SMA connectors. Other models in the family offer different dB values or frequency ranges.

Replacement Considerations

M3933/25-70N is listed as a parameter equivalent substitute. Verify functional equivalence before adoption. Ensure connector gender and impedance match original requirements.
