M3933/14-02S

Overview

The M3933/14-02S is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for military and aerospace applications. It features SMA connectors with a male-to-female configuration and operates at a nominal impedance of 50 Ohms. The component provides a fixed attenuation value of 6 dB across a frequency range extending up to 12.4 GHz. It supports a maximum power rating of 2 Watts and functions within an operating temperature range from -65°C to +165°C.

Feature Summary

• Fixed 6 dB attenuation performance
• Military-grade rugged construction
• Wide operational temperature capability

Applications

• Satellite communication systems
• Radar signal processing
• Test and measurement instrumentation

Procurement Notes

Verify the specific datasheet version for the M3933/14-02S to confirm exact electrical tolerances and mechanical dimensions. Ensure that the procurement channel provides traceability documentation required for MIL-SPEC components. Confirm that the connector gender matches the system requirements, as SMA configurations can vary between plug and jack orientations in different part numbers.

Selection Notes

Select this component when a precise 6 dB reduction is required in high-frequency circuits. The 12.4 GHz bandwidth suits applications needing stable attenuation without significant phase shift. Consider the 2W power handling limit for signal levels. The wide temperature range allows deployment in harsh environments where standard commercial parts would fail.

Part Context

This model belongs to the M3933 series of connectorized attenuators produced by Amphenol SV Microwave. These components are engineered to meet stringent military specifications for reliability and performance. The series utilizes robust SMA interfaces to ensure secure connections in vibration-prone environments typical of defense and aerospace platforms.

Replacement Considerations

M3933/14-03N offers 3 dB attenuation. M3933/14-06S provides 1 dB attenuation. Verify connector gender and attenuation values before substitution.
