M3933/16-25S

Overview

The M3933/16-25S is a screened RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications up to 18 GHz. It features SMA connectors with a female-to-male configuration and maintains a nominal impedance of 50 Ohms. The component provides a fixed attenuation value of 8.5 dB and supports a maximum power rating of 2 W. Operating within a temperature range of -65°C to +165°C, it is classified as an MIL-Spec connectorized attenuator suitable for demanding environments.

Feature Summary

• Provides fixed 8.5 dB attenuation in an inline module format
• Screened construction for enhanced signal integrity
• Compatible with SMA interface standards

Applications

• Military radio systems
• Avionics test equipment
• High-frequency measurement setups

Procurement Notes

Verify the specific attenuation tolerance and frequency response characteristics against the official datasheet before integration. Confirm that the screened variant meets all environmental requirements for the intended deployment. Ensure compatibility with existing SMA mating hardware to maintain system performance.

Selection Notes

Select this model when a precise 8.5 dB reduction is required at frequencies up to 18 GHz. Consider the 2 W power handling limit for thermal management. The screened design offers protection against external interference compared to non-screened alternatives.

Part Context

This part belongs to the M3933 series of connectorized attenuators from Amphenol SV Microwave. These components are engineered to meet rigorous military specifications, ensuring reliability in harsh conditions. The series includes various attenuation values and connector configurations to support diverse RF system needs.

Replacement Considerations

Check for direct substitutes within the M3933/16 family with matching 8.5 dB attenuation and SMA interfaces. Verify that any alternative maintains the same screened construction and 18 GHz operational limit.
