M3933/14-03S

Overview

The M3933/14-03S is a screened 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 fixed attenuation value of 10 dB at a characteristic impedance of 50 Ohms. It supports a power rating of 2 W and functions reliably across an operating temperature range of -55°C to +125°C.

Feature Summary

• Provides precise signal attenuation for high-frequency applications
• Constructed with durable SMA connector interfaces
• Designed for reliable operation in extreme thermal environments

Applications

• Satellite communication systems
• Microwave circuit power level adjustment
• Military radio equipment

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant, as non-screened versions exist under different suffixes like 'N'. Confirm the exact attenuation tolerance and frequency response curves against the official datasheet before integration. Ensure environmental sealing requirements match the screened construction specifications.

Selection Notes

Select this model when a fixed 10 dB reduction is required within the 12.4 GHz bandwidth. Consider the 2 W power handling limit for system design. Compare against non-screened alternatives if environmental protection levels differ from project requirements.

Part Context

This component belongs to the M3933 series of space-grade attenuators designed for satellite microwave circuits. The series offers various attenuation values and connector types, maintaining consistent 50 Ohm impedance and robust performance standards for aerospace and defense sectors.

Replacement Considerations

M3933/14-03N is a parameter-equivalent non-screened alternative.
