M3933/16-53N

Overview

The M3933/16-53N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 24 dB with a 50 Ohm impedance. The device operates across a frequency range from 0 Hz to 18 GHz and supports a maximum power rating of 2 Watts. It utilizes SMA connectors in an inline module configuration. The component is designed for military applications, featuring screened construction and compliance with MIL-DTL-3933 specifications.

Feature Summary

• Screened construction for enhanced electromagnetic interference protection
• Military-grade reliability compliant with MIL-DTL-3933 standards
• SMA connector interface for secure signal transmission
• Fixed 24 dB attenuation value for precise signal control

Applications

• Defense electronic systems requiring stable signal attenuation
• Aerospace communication equipment operating up to 18 GHz
• Test and measurement instrumentation setups
• Harsh environment radio frequency circuits

Procurement Notes

Verify that the specific order includes the 'S' suffix variant if screened construction is required, as this denotes military qualification. Confirm RoHS status, as military variants may not comply with standard environmental directives. Ensure compatibility with existing SMA interfaces and validate power handling requirements against the 2W rating before integration into high-power RF chains.

Selection Notes

Select this model when a fixed 24 dB attenuation is necessary within the DC to 18 GHz bandwidth. The SMA inline format suits board-to-board or cable-to-cable connections. Consider the 2W power limit for system design margins. Verify temperature stability requirements against the specified operational range for extreme environment deployments.
