M3933/25-06N

Overview

The M3933/25-06N is a coaxial RF attenuator manufactured by Amphenol SV Microwave, designed for military and aerospace applications. It features SMA male-to-female connectors with a 50 Ohm impedance. The component operates within a frequency range of DC to 18 GHz and provides a nominal attenuation of 6 dB. It is rated for a maximum power handling of 2 Watts and functions reliably across an operating temperature range of -65°C to +165°C.

Feature Summary

• Provides precise signal attenuation in high-frequency RF circuits
• Supports extreme thermal environments typical of military specifications
• Utilizes robust SMA connector interface for secure interconnects

Applications

• Satellite microwave circuit power level adjustment
• Military radar system signal conditioning
• Aerospace communication equipment testing

Procurement Notes

Verify the specific datasheet revision and manufacturer lot traceability before procurement. Confirm that the SMA connector gender orientation matches the system design requirements. Ensure environmental sealing specifications meet the operational standards for the intended deployment environment. Cross-reference the part number suffixes to confirm material composition and plating options.

Selection Notes

Select this component when a fixed 6 dB attenuation is required at frequencies up to 18 GHz. Consider the 2 Watt power rating against the system's peak power levels. Evaluate the bulk packaging format against assembly line needs. Compare thermal performance against other series if operation exceeds standard limits.

Part Context

This part belongs to the M3933 family of space-grade attenuators from Amphenol SV Microwave. These components are engineered for reliability in harsh environments. The series includes various attenuation values and connector types, all sharing common military qualification standards. This specific model utilizes the SMA interface for compatibility with standard RF infrastructure.

Replacement Considerations

Direct substitutes include M3933/25-08N (8 dB) and M3933/25-31N (5 dB) for similar SMA configurations. Verify connector gender and frequency response when swapping between variants.
