M3933/25-01N

Overview

The M3933/25-01N is a radio frequency military specification attenuator manufactured by Amphenol SV Microwave. It belongs to the SMA connector series and features a male-to-female interface configuration. The component operates with a characteristic impedance of 50 ohms and supports frequencies up to 18 GHz. It provides an attenuation value of 1 dB. The unit is designed for bulk packaging and functions within a temperature range of -65°C to +165°C.

Feature Summary

• Provides precise signal attenuation in RF circuits using SMA connectors
• Constructed for high-temperature operation suitable for harsh environments
• Designed as a non-screened component for standard integration

Applications

• Military radio frequency systems
• Test and measurement equipment requiring fixed attenuation
• High-temperature RF circuit integration

Procurement Notes

Verify the specific datasheet for the M3933/25-01N to confirm current manufacturing status and detailed electrical tolerances. Ensure compatibility with existing SMA interfaces and verify that the non-screened design meets the electromagnetic interference requirements of the target application environment before finalizing procurement.

Selection Notes

Select this component when a fixed 1 dB attenuation is required at frequencies up to 18 GHz. The SMA male-to-female configuration ensures compatibility with standard coaxial connections. Consider the wide operating temperature range if the deployment environment involves extreme thermal conditions, and ensure the non-screened form factor aligns with the system's shielding strategy.

Part Context

This part is part of the M3933 series of RF military specification connectors produced by Amphenol SV Microwave. The series includes various attenuator values and connector types, such as SMA and 2.92mm, designed for robust performance in demanding applications. The M3933/25-01N specifically utilizes the SMA interface standard.

Replacement Considerations

Check for other M3933/25 variants with different attenuation values or screened versions if environmental protection is needed. Verify that any substitute maintains the 50-ohm impedance and 18 GHz frequency limit.
