M3933/14-04S

Overview

The M3933/14-04S is an RF attenuator manufactured by Amphenol SV Microwave. It features SMA male to female connectors and operates within a frequency range of DC to 12.4 GHz. The component provides a nominal attenuation value of 20 dB at a characteristic impedance of 50 Ohms. It supports a maximum power rating of 2 Watts and is packaged in bulk.

Feature Summary

• Provides precise signal attenuation for high-frequency applications
• Utilizes robust SMA connector interface for reliable interconnection
• Designed for military specification environments

Applications

• Satellite communication systems
• Microwave circuit power level adjustment
• RF test and measurement equipment

Procurement Notes

Verify the specific suffix 'S' indicates screened construction, which may differ from non-screened variants like the 'N' suffix. Confirm that the 20 dB attenuation value matches the design requirement, as other models in this series offer different attenuation levels. Ensure compatibility with SMA male-to-female configurations before procurement.

Selection Notes

Select this model when a fixed 20 dB attenuation is required for frequencies up to 12.4 GHz. Consider the 2W power handling capability against system requirements. Compare against other M3933/14 series parts if different attenuation values or connector genders are needed.

Part Context

This component belongs to the M3933 series of space-grade attenuators designed for satellite microwave circuits. It falls under the category of RF MIL Spec Connectors and is part of the SMA series. The product is classified as a connectorized attenuator intended for high-reliability applications.

Replacement Considerations

M3933/14-04N is a parameter-equivalent substitute offering identical electrical specifications but without screening.
