M3933/14-11S

Overview

The M3933/14-11S is a screened RF attenuator manufactured by Amphenol SV Microwave. It features SMA male to female connectors with a 50 Ohm impedance. The component operates within a frequency range of DC to 12.4 GHz and provides a nominal attenuation of 8 dB. It is rated for a maximum power handling of 2 W and functions reliably within an operating temperature range of -65°C to +165°C.

Feature Summary

• Provides precise signal attenuation in high-frequency RF circuits
• Constructed with durable SMA connector interfaces
• Designed for operation in extreme thermal environments

Applications

• Satellite communication systems
• Microwave circuit testing equipment
• Defense radar systems

Procurement Notes

Verify the specific screening level and connector gender configuration against project requirements before ordering. Confirm that the 12.4 GHz frequency limit and 2 W power rating align with system specifications. Ensure compatibility with existing SMA mating hardware to prevent interface mismatches during installation.

Selection Notes

Select this component when a fixed 8 dB attenuation is required at frequencies up to 12.4 GHz. It is suitable for applications demanding high reliability and wide temperature tolerance. Consider the screened construction for enhanced performance stability in sensitive RF environments compared to non-screened variants.

Part Context

This part belongs to the MIL-Spec series of connectorized attenuators from Amphenol SV Microwave. These components are engineered for rigorous military and aerospace standards, ensuring consistent electrical performance under harsh conditions. The SMA interface ensures broad interoperability with standard RF test and measurement infrastructure.

Replacement Considerations

Direct substitutes include other screened SMA attenuators with identical 8 dB attenuation and 12.4 GHz limits, such as the M3933/14-12S or M3933/14-13S, provided they match the male-to-female orientation and power ratings.
