M3933/16-34N

Overview

The M3933/16-34N is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for military and aerospace applications. It operates within a frequency range of DC to 18 GHz with a nominal attenuation value of 14 dB. The component features SMA connectors, providing a male plug on one side and a female jack on the other. It maintains a characteristic impedance of 50 Ohms and supports a maximum power rating of 2 Watts. The unit is constructed as an in-line module suitable for bulk packaging.

Feature Summary

• Provides precise signal attenuation for high-frequency RF circuits
• Features robust SMA interface for secure male-to-female connection
• Designed for reliable operation in demanding military environments

Applications

• Military radar systems
• Aerospace communication equipment
• RF test and measurement instrumentation

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm connector gender orientation and screening requirements. Ensure compatibility with existing SMA interfaces and validate that the 14 dB attenuation value meets system design specifications. Confirm environmental ratings align with operational temperature ranges before procurement.

Selection Notes

Select this component when a fixed 14 dB attenuation is required at frequencies up to 18 GHz. Consider the SMA form factor for ease of integration into standard RF chains. Evaluate the 2W power handling capability against peak signal levels. Verify mechanical dimensions and mounting requirements for the specific application enclosure.

Part Context

This model belongs to the M3933 series of RF MIL Spec Connectors produced by Amphenol SV Microwave. The series includes various attenuator values and configurations tailored for defense and space applications. The M3933 designation indicates compliance with specific military standards for reliability and performance in harsh conditions.

Replacement Considerations

Cross-reference with M3933/16-34S if screened versions are required. Check equivalent models from other manufacturers offering 14 dB SMA attenuators rated for 18 GHz. Ensure substitute parts match the 50 Ohm impedance and 2W power rating.
