M3933/25-38S

Overview

The M3933/25-38S is a screened SMA male-to-female RF attenuator manufactured by Amphenol SV Microwave. It operates within an 18 GHz frequency range with a 50 Ohm impedance. The component provides 18 dB of attenuation and supports a power rating of 2 W. It functions reliably between -65°C and +165°C, meeting MIL-Spec standards for rugged applications.

Feature Summary

• Screened construction for enhanced environmental protection
• SMA connector interface ensuring compatibility
• High-temperature operational capability

Applications

• Military communication systems
• Radar equipment signal conditioning
• Test and measurement instrumentation

Procurement Notes

Verify the specific attenuation value against official datasheets as suffix variations exist within this series. Confirm screening status and connector gender orientation prior to integration. Ensure environmental ratings match operational requirements.

Selection Notes

Select based on required attenuation level and frequency stability. Verify impedance matching for system integrity. Consider thermal management capabilities given the wide operating temperature range specified for military-grade components.

Part Context

This part belongs to the M3933/25 series of screened SMA attenuators. It shares design characteristics with other variants in the family, differing primarily in attenuation values and screening specifications while maintaining consistent electrical interfaces.

Replacement Considerations

Compatible substitutes include M3933/25-XXS series variants. Verify exact attenuation and screening requirements when selecting alternatives from the same manufacturer line.
