M3933/14-08S

Overview

The M3933/14-08S is a fixed RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications up to 12.4 GHz. It features SMA male-to-female connectors and maintains a 50 Ohm impedance. The unit provides a nominal attenuation of 4 dB with a screened construction suitable for military specifications. It operates within a temperature range of -65°C to +165°C and handles a power rating of 2 W.

Feature Summary

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

Applications

• Satellite communication systems
• Radar equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific screening requirements against your system's environmental standards. Confirm that the SMA interface matches your existing cabling infrastructure. Ensure the 4 dB attenuation value aligns with your circuit design needs. Check for any specific handling instructions related to the screened housing during installation.

Selection Notes

Select this component when a precise 4 dB reduction is required in the 12.4 GHz band. The screened variant offers superior isolation compared to non-screened versions. Consider the wide temperature tolerance for harsh environment deployments. Ensure compatibility with standard SMA mating hardware.

Part Context

This part belongs to the M3933 series of connectorized attenuators from Amphenol SV Microwave. These components are engineered for reliability in demanding RF environments. The series includes various attenuation values and connector configurations to support diverse microwave circuit designs.

Replacement Considerations

Direct substitutes include other screened SMA attenuators with identical 4 dB attenuation and 12.4 GHz frequency limits. Verify mechanical dimensions and pinout compatibility before substitution. Non-screened equivalents may require additional shielding measures.
