M3933/25-16S

Overview

The M3933/25-16S is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications. It features SMA connectors with a male-to-female configuration and maintains a 50 Ohm impedance. The component provides a nominal attenuation of 16 dB across a frequency range of DC to 18 GHz. It supports a maximum power rating of 2 Watts and operates within a temperature range of -65°C to +165°C. Packaged in bulk, this screened unit meets military specifications for reliable performance.

Feature Summary

• Provides fixed 16 dB signal attenuation for RF circuitry
• Utilizes SMA connector interface for standard integration
• Operates reliably from DC up to 18 GHz frequency range
• Screened construction ensures compliance with military standards

Applications

• RF test and measurement equipment requiring precise signal reduction
• Military communication systems adhering to MIL-Spec requirements
• High-frequency electronic circuits needing stable impedance matching
• Aerospace instrumentation operating under extreme thermal conditions

Procurement Notes

Verify the specific suffix 'S' indicates the screened variant when sourcing replacements. Confirm that the SMA gender configuration matches the system design requirements. Ensure the 16 dB attenuation value aligns with the target signal levels. Check that the 2W power rating suffices for the intended application environment. Validate compatibility with existing bulk packaging handling procedures.

Selection Notes

Select this model when a fixed 16 dB reduction is necessary within the 18 GHz bandwidth. Consider the SMA interface for direct connection to compatible RF components. Evaluate the 2W power handling capability against peak signal loads. Assess the wide temperature range suitability for harsh operational environments. Compare against other M3933 series variants if different attenuation values are required.
