M3933/14-11N

Overview

The M3933/14-11N is a fixed attenuator manufactured by Amphenol SV Microwave, designed for RF applications up to 12.4 GHz. It features SMA male-to-female connectors and maintains a 50 Ohm impedance. The unit provides an attenuation value of 8 dB with a power rating of 2 W. Operating temperatures range from -65°C to +165°C. This component is classified as a nonscreened interconnect device within the MIL-Spec connector category.

Feature Summary

• Provides fixed signal attenuation in a compact inline module format
• Utilizes SMA gendered connectors for secure interconnection
• Engineered for high-temperature operation in demanding environments

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement instrumentation
• Military communication systems requiring precise signal reduction

Procurement Notes

Verify the specific suffix 'N' indicates nonscreened construction when sourcing. Confirm that the 12.4 GHz frequency limit aligns with system requirements. Ensure compatibility with SMA mating interfaces. Check for RoHS compliance status if required by project specifications. Validate operating temperature ranges against environmental conditions.

Selection Notes

Select this model when an 8 dB fixed attenuation is required at frequencies up to 12.4 GHz. Consider the nonscreened design if shielding is provided externally or is unnecessary. Ensure the 2 W power handling capacity meets peak signal levels. Verify SMA connector gender matches the system topology.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. These components are widely used in aerospace and defense sectors. The series offers various attenuation values and connector types. The M3933 designation signifies a standardized military-style connectorized attenuator.

Replacement Considerations

M3933/14-11S is a screened variant of the same electrical specification. Verify if shielding requirements differ between nonscreened and screened versions. Other M3933/14 models offer different attenuation values.
