M3933/25-15N

Overview

The M3933/25-15N is an RF MIL Spec connector manufactured by Amphenol / SV Microwave. It belongs to the SMA series and features a male-to-female attenuator configuration. The component operates at a maximum frequency of 18 GHz with a nominal impedance of 50 ohms. It provides a fixed attenuation value of 15 dB. The device is designed for nonscreened applications and supports a cable type rated up to 12.4 GHz. Operating temperature limits range from -65 °C to +165 °C.

Feature Summary

• Fixed attenuation capability within the SMA connector interface
• Military specification compliance for rugged environments
• Wide operational temperature range suitable for extreme conditions

Applications

• RF power level adjustment in satellite microwave circuits
• Signal conditioning in high-frequency communication systems
• Test and measurement equipment requiring precise signal reduction

Procurement Notes

Verify the specific datasheet version for the M3933/25-15N to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with existing SMA interfaces in the target assembly. Check for any updated environmental certifications or material composition changes that may affect procurement specifications for military or aerospace projects.

Selection Notes

Select this component when a fixed 15 dB attenuation is required within an SMA connectorized system operating up to 18 GHz. Consider the nonscreened design if shielding is provided externally. Verify that the 50 ohm impedance matches the system requirements and that the temperature range meets the operational environment constraints.

Part Context

This part is part of the M3933 series of connectorized attenuators from Amphenol SV Microwave. These components are designed to integrate attenuation directly into the connector interface, reducing the need for separate inline attenuator modules. The series offers various attenuation values and connector types to support diverse RF system architectures.

Replacement Considerations

M3933/25-12S: Provides 12 dB attenuation with screened construction. M3933/25-27N: Offers 1 dB attenuation in a nonscreened configuration. M3933/25-08N: Features 8 dB attenuation in a nonscreened design. Verify attenuation value and screening requirements before substitution.
