M3933/16-26S

Overview

The M3933/16-26S is a screened RF attenuator manufactured by Amphenol SV Microwave, designed for military specifications. It features SMA female to male connectors and operates within an 18 GHz frequency range. The component provides a nominal attenuation of 26 dB at a 50 Ohm impedance. It supports a power rating of 2 W and functions reliably across a temperature range of -65°C to +165°C.

Feature Summary

• Screened construction for enhanced reliability in military applications
• Fixed attenuation design utilizing SMA connector interface
• High-temperature operational capability up to +165°C

Applications

• Military RF signal conditioning systems
• Test and measurement equipment requiring fixed attenuation
• Avionics signal path management

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm screening status and connector gender orientation. Ensure that the required attenuation value matches the application needs, as this model provides a fixed 26 dB reduction. Confirm environmental ratings align with the intended operating conditions before procurement.

Selection Notes

Select this component when a fixed 26 dB attenuation is required within an 18 GHz bandwidth. Consider the SMA interface compatibility with existing system cabling. Evaluate the 2 W power handling capacity against peak signal levels. Verify that the screened variant meets specific military environmental standards if applicable.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. These components are engineered for high-reliability environments, often adhering to MIL-SPEC standards. The series includes various attenuation values and connector configurations to support diverse RF system requirements.

Replacement Considerations

Direct substitutes include other M3933/16 variants with different attenuation values, such as M3933/16-07S or M3933/16-09S, provided the attenuation difference is acceptable. Cross-reference with equivalent screened SMA attenuators from other manufacturers if supply constraints exist.
