M3933/16-19S

Overview

The M3933/16-19S is a screened RF attenuator manufactured by Amphenol SV Microwave. It operates within the SMA connector series with a 50 Ohm impedance. The device provides a fixed attenuation of 2.5 dB across a frequency range from 0 Hz to 18 GHz. It supports a maximum power rating of 2 W and functions reliably between -65°C and +165°C. The unit features an SMA female-to-male configuration and is packaged in bulk.

Feature Summary

• Screened construction for military specification compliance
• Fixed 2.5 dB attenuation value
• Wide operational temperature range up to +165°C

Applications

• Military radio systems
• Avionics signal conditioning
• Test and measurement equipment requiring screened components

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant required for your application. Confirm that the SMA gender configuration matches your system interface. Ensure the 2W power rating and 18GHz frequency limit are sufficient for your operational parameters before ordering.

Selection Notes

Select this component when a screened MIL-spec attenuator is mandatory. The SMA interface suits standard coaxial connections. Consider the 2.5dB fixed value; variable or different attenuation levels require alternative part numbers within the M3933/16 series.

Part Context

This part belongs to the M3933/16 series, which covers SMA connectors up to 18 GHz. It is distinct from the M3933/30 series (2.92mm) and M3933/25 series (SMA reverse polarity). The 'S' suffix denotes screening, differentiating it from non-screened variants like the N suffix.

Replacement Considerations

M3933/16-19N is a parameter-equivalent substitute from the same manufacturer. Verify if the non-screened version meets environmental requirements.
