M3933/16-16S

Overview

The M3933/16-16S is a screened RF attenuator manufactured by Amphenol SV Microwave. It utilizes SMA female-to-male connectors with a 50 Ohm impedance. The component operates within a frequency range up to 18 GHz and provides 0 dB attenuation. It features a power rating of 2 W and functions across a temperature range from -65 °C to +165 °C.

Feature Summary

• Screened construction for military specification reliability
• SMA gender-changing interface design
• Wide operational temperature capability

Applications

• Military radio systems
• Avionics signal conditioning
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet revision and screening level (e.g., MIL-PRF-39012) upon order confirmation. Confirm that the 0 dB attenuation value matches the system requirement, as this model may serve as a direct pass-through replacement. Ensure connector gender orientation aligns with the assembly interface.

Selection Notes

Select this part when a screened SMA attenuator with zero insertion loss is required for high-reliability applications. The wide temperature range supports extreme environments. Verify that the 2 W power handling meets the signal path requirements before integration into the circuit design.

Part Context

This component belongs to the M3933 series of screened RF attenuators designed for harsh environments. It is part of the broader Amphenol SV Microwave portfolio of military-grade interconnect solutions. The series offers various attenuation values and connector types to support diverse defense and aerospace communication architectures.

Replacement Considerations

Direct substitutes include other screened SMA attenuators with identical 0 dB attenuation and 50 Ohm impedance. Verify that alternative parts meet the same MIL-PRF-39012 screening standards and physical dimensions to ensure compatibility without mechanical modification.
