M3933/30-21S

Overview

The M3933/30-21S is a screened RF attenuator manufactured by Amphenol SV Microwave. It utilizes 2.92mm connectors with female-to-male configuration. The device operates within a frequency range of 0 Hz to 40 GHz, supporting a maximum frequency of 40 GHz. It provides a nominal attenuation of 10 dB at a characteristic impedance of 50 Ohms. The unit handles a power rating of 2 W and functions within an operating temperature range of -65 °C to +165 °C.

Feature Summary

• Screened construction for enhanced signal integrity
• Military specification compliance via MIL-DTL-3933 series
• Wideband operation up to 40 GHz

Applications

• RF test and measurement instrumentation
• Defense and aerospace communication systems
• High-frequency circuit calibration

Procurement Notes

Verify the specific suffix 'S' indicates screened construction when ordering. Confirm that the 2.92mm interface matches the system requirements. Ensure the 10 dB attenuation value aligns with the design specifications. Check for RoHS3 compliance status if required by project standards. Validate the military specification designation against procurement documentation.

Selection Notes

Select this component for applications requiring precise attenuation in high-frequency environments. The 2.92mm interface offers superior performance compared to SMA variants. Consider the screened version for sensitive RF setups. Verify the 2 W power handling capability meets system needs. Evaluate the wide temperature range for harsh environment suitability.

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 variant specifically uses 2.92mm connectors. This model represents a screened option within the product line.

Replacement Considerations

M3933/30-21N is a parameter-equivalent non-screened alternative from Amphenol SV Microwave. R413309000 from Radiall USA, Inc. is another parameter-equivalent substitute.
