M3933/16-20N

Overview

The M3933/16-20N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides an attenuation value of 3.5 dB with a 50 Ohm impedance. The component operates within a frequency range of 0 Hz to 18 GHz and supports a power rating of 2W. It utilizes SMA connectors in an inline module configuration.

Feature Summary

• Provides precise signal attenuation for RF applications
• Operates across a wide microwave frequency spectrum
• Features robust SMA connector interface

Applications

• Military communication systems
• Aerospace instrumentation
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'N' against official datasheets to confirm material composition and plating specifications, as military-grade variants often have distinct environmental compliance requirements. Confirm that the SMA gender configuration matches the system interconnect needs before finalizing procurement orders.

Selection Notes

Select this model when a low attenuation value of 3.5 dB is required for impedance matching or signal level adjustment in high-frequency circuits. Ensure the 2W power handling capacity aligns with the maximum expected signal power in the application path to prevent component damage during operation.

Part Context

This part belongs to the M3933/16 series of fixed attenuators designed for harsh environment applications. The series is characterized by its use of SMA connectors and capability to operate up to 18 GHz, serving critical roles in defense and aerospace RF signal processing chains.

Replacement Considerations

Direct substitutes include other M3933/16 series parts with identical attenuation values, such as those from the same manufacturer family. Verify connector gender and physical dimensions to ensure mechanical compatibility with existing mounting structures.
