M3933/14-03S

Overview

The M3933/14-03S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a nominal attenuation of 10 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 inline module configuration.

Feature Summary

• Provides precise 10 dB signal attenuation for RF applications
• Operates reliably up to 12.4 GHz frequency range
• Supports 2 Watt power handling capacity
• Features durable SMA connector interface

Applications

• RF signal level reduction in test and measurement equipment
• Attenuation stages in communication systems
• Signal conditioning in radar systems
• Integration into microwave circuit assemblies

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact attenuation tolerance and connector gender specifications. Ensure compatibility with existing system impedance requirements before procurement. Confirm current availability status directly with authorized distributors as lead times may vary.

Selection Notes

Select this component when a fixed 10 dB attenuation value is required within the 12.4 GHz bandwidth. Consider the 2W power rating for thermal management in high-power environments. Verify that the SMA inline form factor fits the physical constraints of the target assembly compared to other series variants.

Part Context

This model belongs to the M3933/14 series of connectorized attenuators. It shares the same mechanical housing and connector type as other values in the series, such as the M3933/14-14S, differing primarily in internal resistive network design to achieve specific attenuation levels while maintaining consistent electrical performance characteristics.

Replacement Considerations

M3933/14-06S offers 1 dB attenuation. M3933/14-14S offers 40 dB attenuation. Both share identical SMA interfaces and frequency ranges.
