M3933/14-01N

Overview

The M3933/14-01N is a fixed RF attenuator manufactured by Amphenol SV Microwave. It features SMA male to female connectors and operates within a frequency range of 0 Hz to 12.4 GHz. The component provides a nominal attenuation of 3 dB with a 50 Ohm impedance. It has a power rating of 2 W and functions in nonscreened configurations. The unit is designed for inline module applications.

Feature Summary

• Provides precise signal attenuation via fixed internal resistive elements
• Ensures stable impedance matching through 50 Ohm design
• Supports high-frequency operation up to 12.4 GHz
• Utilizes robust SMA connector interface for reliable interconnect

Applications

• RF signal path conditioning in communication systems
• Test and measurement equipment calibration
• Military and aerospace electronic assemblies
• High-frequency circuit protection and level adjustment

Procurement Notes

Verify the specific suffix 'N' confirms the nickel-plated finish and nonscreened construction as documented. Confirm that the SMA gender configuration matches the required male-to-female topology for the target assembly. Ensure environmental ratings align with operational temperature requirements before procurement.

Selection Notes

Select this model when a 3 dB fixed attenuation is required at frequencies up to 12.4 GHz. The SMA interface suits standard coaxial connections. Consider the nonscreened variant if shielding is provided externally or is unnecessary for the specific application environment.

Part Context

This part belongs to the M3933 series of RF attenuators from Amphenol SV Microwave. These components are engineered for high-reliability applications, often meeting military specifications. The series offers various attenuation values and connector types to support diverse RF system architectures.

Replacement Considerations

The M3933/14-01S is a screened version of the same electrical specification. Verify if shielding requirements differ between the N and S suffixes. Other series members may offer different attenuation values or connector interfaces.
