M3933/30-11N

Overview

The M3933/30-11N is a 2.92mm female-to-male RF attenuator manufactured by Amphenol SV Microwave. It provides a fixed attenuation of 5 dB with a 50 Ohm impedance. The device operates from DC to 32 GHz and supports a power rating of 2 W. It features SMA single-row module packaging, a bulk package type, and an operating temperature range of -65°C to +165°C.

Feature Summary

• Fixed 5 dB attenuation in a compact 2.92mm connectorized form factor
• High-frequency operation up to 32 GHz for precision signal control
• Robust thermal performance suitable for extreme environments (-65°C to +165°C)
• SMA single-row module construction for reliable interconnect applications

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement instrumentation
• Military and aerospace communication systems
• High-frequency signal distribution networks

Procurement Notes

Verify the specific suffix 'N' indicates the nonscreened variant when sourcing replacements. Confirm that the SMA single-row module interface matches the system requirements. Ensure the 5 dB attenuation value aligns with the design specifications. Check for RoHS3 compliance if environmental regulations apply. Validate the 2 W power rating against peak operational loads.

Selection Notes

Select this component for applications requiring precise 5 dB attenuation within the 2.92mm frequency range. Consider the nonscreened body style for standard integration needs. Evaluate the 2 W power handling capability against system requirements. Ensure the SMA single-row module form factor fits the available space. Verify compatibility with the -65°C to +165°C operating environment.

Part Context

This part belongs to the M3933 series of RF attenuators designed for high-reliability applications. It utilizes the 2.92mm connector interface to support frequencies up to 40 GHz theoretically, though this specific model is rated to 32 GHz. The series is known for its use in military and aerospace sectors where stability and precision are critical.

Replacement Considerations

M3933/30-11S is a parameter-equivalent screened variant from the same manufacturer.
