M3933/14-23S

Overview

The M3933/14-23S is a coaxial RF attenuator module manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides an attenuation value of 1.5 dB with a 50 Ohm impedance. The device operates within a frequency range of 0 Hz to 12.4 GHz and supports a power rating of 2 Watts. It utilizes SMA connectors in an in-line configuration.

Feature Summary

• Provides precise 1.5 dB signal attenuation for RF applications
• Operates reliably across a wide frequency spectrum up to 12.4 GHz
• Constructed as a robust coaxial in-line module for direct integration

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• Military and aerospace electronic subsystems requiring MIL-DTL-M3933 compliance

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and connector gender variations. Ensure compatibility with existing SMA interfaces and validate that the 2W power rating meets system requirements. Confirm RoHS status and military qualification standards prior to procurement.

Selection Notes

Select this component when a low attenuation value of 1.5 dB is required within the 12.4 GHz bandwidth. Consider the 50 Ohm impedance match for standard RF environments. Evaluate the SMA interface type and physical form factor against board layout constraints. Verify thermal management capabilities for continuous 2W operation.

Part Context

This part belongs to the M3933 series of connectorized attenuators, designed for high-reliability applications. The M3933/14 sub-series typically covers frequencies up to 12.4 GHz. These components are engineered to meet stringent military specifications, ensuring consistent performance in demanding operational environments compared to commercial-grade alternatives.

Replacement Considerations

Cross-reference with other M3933/14 variants for different attenuation values. Check for updated manufacturing revisions from Cinch Connectivity Solutions. Verify mechanical dimensions against legacy designs if space is constrained.
