M3933/16-04N

Overview

The M3933/16-04N is a radio frequency attenuator manufactured by Amphenol SV Microwave. It features SMA connectors with a female-to-male configuration and operates within a frequency range of DC to 18 GHz. The component provides an attenuation value of 20 dB at a characteristic impedance of 50 Ohms. It supports a maximum power rating of 2 W and functions reliably across a temperature range of -65 °C to +165 °C. This non-screened unit is packaged in bulk.

Feature Summary

• Provides precise signal attenuation for RF applications
• Utilizes robust SMA connector interface
• Designed for high-temperature military environments

Applications

• Satellite communication systems
• Military radar equipment
• Microwave circuit testing

Procurement Notes

Verify the specific suffix 'N' indicates the non-screened variant, distinct from screened versions. Confirm that the SMA gender order matches system requirements. Ensure environmental ratings align with operational limits. Check current availability as lead times may vary.

Selection Notes

Select this model when a fixed 20 dB reduction is required at 50 Ohms. Consider the 18 GHz upper frequency limit for bandwidth needs. Evaluate the non-screened construction against shielding requirements. Verify power handling capabilities for the specific signal levels.

Part Context

This part belongs to the M3933 series of space-grade attenuators. These components are designed for satellite microwave circuits. They offer reliable performance in harsh conditions. The series includes various attenuation values and connector types.

Replacement Considerations

M3933/16-04S is a parameter-equivalent screened alternative.
