M3933/25-07N

Overview

The M3933/25-07N is a coaxial space attenuator manufactured by Amphenol SV Microwave, designed for RF applications up to 18 GHz. It features SMA male-to-female connectors and provides a nominal attenuation of 7 dB at 50 ohms impedance. The component operates within a temperature range of -65°C to +165°C and is classified as a non-screened unit.

Feature Summary

• Provides precise signal attenuation in the 7 dB range for RF power level control
• Utilizes SMA connector interface for secure male-to-female interconnection
• Engineered for high-temperature stability with operation up to +165°C

Applications

• Satellite microwave circuit power level adjustment
• RF test and measurement equipment calibration
• Military and aerospace communication systems

Procurement Notes

Verify the specific datasheet version for the M3933/25-07N to confirm current manufacturing status and detailed electrical tolerances. Ensure compatibility with existing SMA interfaces and thermal management requirements for the target operating environment before finalizing procurement.

Selection Notes

Select this model when a fixed 7 dB attenuation is required for SMA-based systems operating below 18 GHz. Consider the non-screened construction for applications where external shielding is provided or not critical. Verify that the 50-ohm impedance matches the system design requirements.

Part Context

This part belongs to the M3933 series of space attenuators from Amphenol SV Microwave. These components are specifically designed for satellite and microwave circuits, offering reliable performance in demanding environments compared to standard commercial attenuators.

Replacement Considerations

Direct substitutes include other M3933 series variants with different attenuation values, such as M3933/25-08N (8 dB) or M3933/25-67N (4.5 dB), provided the specific attenuation requirement can be adjusted.
