M3933/25-02S

Overview

The M3933/25-02S is a fixed attenuator from the SMA series manufactured by Amphenol SV Microwave. It provides a nominal attenuation of 2 dB with a 50 Ohm impedance. The component operates within a frequency range of 0 Hz to 18 GHz and supports a maximum power rating of 2 W. Designed for military specifications, it features SMA male to female connectors and functions reliably between -65°C and +165°C.

Feature Summary

• Provides precise signal attenuation in high-frequency RF applications
• Constructed for reliable operation under extreme temperature conditions
• Designed as an inline module for seamless circuit integration

Applications

• Military radio systems requiring signal level control
• Test and measurement instrumentation setups
• High-frequency communication equipment calibration

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm SMA connector gender and attenuation value. Ensure environmental ratings match operational requirements. Confirm compliance with relevant military standards before procurement.

Selection Notes

Select this model when a low attenuation value near 2 dB is required for SMA interfaces. Consider the 18 GHz upper frequency limit and 2W power handling capacity. Verify that the operating temperature range meets system demands.

Part Context

This component belongs to the M3933 family of RF attenuators designed for rugged environments. It utilizes standard SMA interfaces to ensure compatibility with existing military-grade interconnects while maintaining signal integrity at high frequencies.

Replacement Considerations

M3933/25-02N serves as a parameter-equivalent alternative within the same product line.
