M3933/25-85S

Attenuators Overview

The M3933/25-85S is a screened SMA male-to-female fixed attenuator manufactured by Amphenol SV Microwave. It operates within a frequency range of DC to 18 GHz with a nominal attenuation value of 17 dB. The component maintains a 50 Ohm impedance and supports a power rating of 2 W. Designed for military specifications, it functions reliably between -65°C and +165°C.

Attenuators Feature Summary

• Screened construction for enhanced signal integrity
• Military specification compliance
• Wide operational temperature range

Attenuators Applications

• Military communication systems
• Aviation radar equipment
• Test and measurement instrumentation

Attenuators Procurement Notes

Verify the specific screening status and exact attenuation tolerance against the manufacturer's datasheet before integration. Confirm that the SMA gender configuration matches the system interface requirements. Ensure environmental ratings meet the operational extremes of the intended deployment scenario.

Attenuators Selection Notes

Select this model when a high-attenuation value near 17 dB is required in an SMA form factor. Consider the screened variant if electromagnetic interference shielding is critical. Verify compatibility with existing SMA connectors and ensure the 2 W power handling meets system peak levels.

Attenuators Part Context

This part belongs to the M3933 series of RF military specification connectors. It utilizes the standard SMA interface geometry. The product line includes various attenuation values and gender combinations to support diverse RF circuit needs in harsh environments.

Attenuators Replacement Considerations

Cross-reference with other M3933/25-XXS variants for different attenuation levels. Verify mechanical dimensions and mating force characteristics against alternative screened SMA attenuators from other manufacturers to ensure interchangeability.
