M3933/25-38N

Overview

The M3933/25-38N is a fixed RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It features SMA connectors and provides a nominal attenuation of 12 dB at 50 Ohms impedance. The device supports a frequency range up to 12.4 GHz with a maximum power rating of 2 W. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides precise signal attenuation for RF systems
• Utilizes durable SMA connector interface
• Designed for high-power applications up to 2W

Applications

• RF test and measurement equipment
• Military and aerospace communication systems
• Microwave circuit design and prototyping

Procurement Notes

Verify the specific suffix 'N' against official datasheets to confirm compliance requirements, as military-grade variants often have distinct qualification standards. Confirm that the 12 dB attenuation value matches the system design needs before ordering. Ensure environmental ratings meet operational temperature extremes.

Selection Notes

Select this component when a fixed 12 dB reduction is required in a 50 Ohm system operating below 12.4 GHz. Consider the SMA interface compatibility with existing cabling. Evaluate the 2W power handling capability against peak signal levels to prevent damage.

Part Context

This part belongs to the M3933/25 series of connectorized attenuators. These components are typically screened or qualified for demanding environments. The series offers various attenuation values while maintaining consistent electrical performance across the specified frequency bands.

Replacement Considerations

Check for direct equivalents such as other M3933/25 variants with identical 12 dB attenuation. Verify that substitute parts maintain the same SMA male/female configuration and 50 Ohm impedance to ensure mechanical and electrical compatibility.
