M3933/30-25N

Overview

The M3933/30-25N is a non-screened RF attenuator manufactured by Amphenol SV Microwave. It utilizes a 2.92mm connector interface with female-to-male gender configuration. The component operates within a frequency range of 0 Hz to 40 GHz and provides a nominal attenuation value of 12 dB. It maintains a characteristic impedance of 50 Ohms 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

• Provides precise signal attenuation in high-frequency RF circuits
• Features robust construction for military specification environments
• Supports wideband operation up to 40 GHz

Applications

• Military radar systems
• Satellite communication equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'N' indicates the non-screened variant, as screened versions exist with different suffixes. Confirm that the 2.92mm interface matches the system requirements. Ensure the 12 dB attenuation value aligns with the circuit design needs. Check for RoHS compliance status if required by the project specifications.

Selection Notes

Select this model when a fixed 12 dB attenuation is required at frequencies up to 40 GHz. The 2.92mm interface offers higher performance limits compared to SMA connectors. Consider the non-screened design if shielding is provided by the enclosure. Verify power handling capabilities against peak signal levels in the application.

Part Context

This part belongs to the M3933 series of connectorized attenuators designed for MIL-Spec applications. It is distinct from screened variants like the M3933/30-21S. The product line focuses on high-reliability interconnect solutions for defense and aerospace sectors requiring stable RF performance under extreme conditions.

Replacement Considerations

M3933/30-21S is a parameter-equivalent screened alternative.
