M3933/25-58N

Overview

The M3933/25-58N is an RF attenuator manufactured by Cinch Connectivity Solutions Midwest Microwave. It provides a fixed attenuation value of 0 dB with a 50 Ohm impedance. The component operates within a frequency range of 0 Hz to 18 GHz and supports a maximum power dissipation of 2 Watts. It utilizes an SMA In-Line Module package configuration.

Feature Summary

• Provides zero-decibel signal transmission for circuit matching or bypass applications
• Operates at standard 50 Ohm system impedance
• Supports high-frequency signals up to 18 GHz
• Handles continuous power loads of 2 Watts

Applications

• RF test and measurement setups requiring signal path continuity
• Circuit board design for impedance matching or dummy loads
• Signal routing in microwave communication systems

Procurement Notes

Verify the specific manufacturer part number against official Cinch Connectivity Solutions documentation to confirm current availability status. Ensure that the SMA interface and 50 Ohm impedance requirements align with the target system design before ordering. Check for any updated environmental compliance declarations if required by project specifications.

Selection Notes

Select this component when a fixed, non-attenuating connection is required within an RF chain. The 0 dB specification indicates it functions primarily as a structural connector rather than a signal reducer. Confirm that the 2W power rating and 18 GHz frequency limit meet the operational demands of the intended application environment.

Part Context

This part belongs to the M3933/25 series of coaxial attenuators from Midwest Microwave. While many variants in this series provide specific attenuation values, the -58N suffix denotes a 0 dB configuration. It shares the same physical SMA module form factor and electrical construction principles as other members of this military-grade compatible family.

Replacement Considerations

Direct substitutes include other 0 dB SMA attenuators from manufacturers such as Pasternack or Amphenol, provided they match the 50 Ohm impedance and 18 GHz frequency range. Verify mechanical dimensions and pin compatibility for direct replacement in existing assemblies.
