M3933/30-09S

Overview

The M3933/30-09S is a screened RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications. It features SMA single-row module connectors with a male-to-female configuration. The component operates within a frequency range of 0 Hz to 32 GHz and maintains a characteristic impedance of 50 Ohms. It provides a fixed attenuation value of 4 dB and supports a power rating of 2 W. The unit functions reliably across an operating temperature range from -65 °C to +165 °C.

Feature Summary

• Screened construction for enhanced environmental protection
• SMA single-row module connector interface
• Fixed 4 dB attenuation performance

Applications

• High-frequency signal conditioning in test and measurement equipment
• Attenuation stages in radar systems
• Signal level adjustment in communication infrastructure

Procurement Notes

Verify the specific screening requirements against project specifications before procurement. Confirm that the SMA connector gender matches the system interconnect needs. Ensure the thermal environment remains within the specified operational limits. Check for RoHS3 compliance status if required by regulatory standards. Validate the 2 W power rating against peak signal levels.

Selection Notes

Select this component when a fixed 4 dB reduction is required at frequencies up to 32 GHz. The screened variant is suitable for environments requiring additional shielding. Consider the SMA interface compatibility with existing cabling. Evaluate the 50 Ohm impedance match for system integrity. Assess the wide temperature range suitability for harsh conditions.

Part Context

This part belongs to the M3933 series of connectorized attenuators from Amphenol SV Microwave. The series includes various attenuation values and connector types. The M3933/30-09S specifically utilizes SMA connectors. Other variants in the family offer different dB ratings or connector interfaces. The series is designed for reliable performance in demanding RF applications.

Replacement Considerations

M3933/30-09N is a parameter-equivalent substitute from Amphenol SV Microwave. R413304000 from Radiall USA, Inc. is another parameter-equivalent option. Verify connector gender and attenuation values when substituting.
