M3933/25-71N

Overview

The M3933/25-71N is a coaxial RF attenuator manufactured by Cinch Connectivity Solutions under the Midwest Microwave brand. It provides a fixed attenuation value of 6.5 dB with a frequency range extending from 0 Hz to 18 GHz. The component features a 50 Ohm impedance and supports a maximum power dissipation of 2 Watts. It utilizes SMA connectors in an inline module configuration, designed for reliable performance in high-frequency signal processing applications.

Feature Summary

• Provides precise fixed attenuation for signal level control
• Operates across a wide frequency spectrum up to 18 GHz
• Constructed as a robust coaxial inline module

Applications

• RF signal conditioning in communication systems
• Test and measurement equipment calibration
• Military and aerospace electronic subsystems

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct connector type and attenuation tolerance. Confirm that the required operating temperature range aligns with the component's specifications. Ensure compatibility with existing SMA interfaces in the target assembly before procurement.

Selection Notes

Select this model when a fixed 6.5 dB reduction is required within the DC to 18 GHz bandwidth. Ensure the system can handle the 2W power rating without thermal issues. Verify that the SMA inline form factor fits the mechanical constraints of the installation environment.

Part Context

This component belongs to the M3933/25 series of coaxial attenuators. It shares the same physical footprint and electrical interface characteristics as other variants in the series, differing primarily in the specific attenuation value provided. The series is designed for consistent performance across various military and industrial standards.

Replacement Considerations

M3933/25-71S is a potential substitute variant offering similar electrical characteristics with different connector plating or material specifications. Verify exact dimensional and electrical tolerances before substitution.
