M3933/25-26S

Overview

The M3933/25-26S is a fixed RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It features SMA connectors and provides a nominal attenuation of 30 dB. The device operates within a frequency range of 0 Hz to 2 GHz and has a power rating of 2 W. It is designed for a characteristic impedance of 50 Ohms. The component utilizes an in-line module package configuration, suitable for direct integration into coaxial signal paths.

Feature Summary

• Provides precise 30 dB signal attenuation for RF applications
• Operates reliably up to 2 GHz frequency range
• Supports 2 W power handling capacity
• Features standard SMA connector interface

Applications

• RF signal level reduction in communication systems
• Test and measurement equipment signal conditioning
• Military and aerospace electronic subsystems
• Circuit protection via signal attenuation

Procurement Notes

Verify the specific suffix 'S' against official datasheets to confirm connector gender and screening requirements. Ensure compatibility with MIL-DTL-M3933 standards if military qualification is required. Confirm operating temperature ranges match system specifications before procurement.

Selection Notes

Select this model when a fixed 30 dB attenuation is required at frequencies up to 2 GHz. Consider the 2 W power rating for high-power signal paths. Verify SMA connector compatibility with existing PCB or cable assemblies. Evaluate environmental ratings for extreme temperature operation if necessary.

Part Context

This component belongs to the M3933 series of connectorized attenuators from Cinch Connectivity Solutions. The series offers various attenuation values and frequency ranges. The M3933/25 variant specifically targets higher frequency operations compared to lower-frequency counterparts in the same family line.

Replacement Considerations

Check for exact part number matches in inventory. Generic replacements may not meet MIL-DTL-M3933 specifications. Verify that substitute components maintain identical 30 dB attenuation and 2 GHz frequency limits.
