M3933/14-09S

Overview

The M3933/14-09S is a screened RF attenuator interconnect manufactured by Amphenol SV Microwave. It utilizes SMA connectors with a male-to-female configuration, providing a nominal attenuation of 5 dB. The component operates within a frequency range of DC to 12.4 GHz and maintains a characteristic impedance of 50 Ohms. It supports a maximum power rating of 2 W and functions reliably across an operating temperature range of -65°C to +165°C. Packaged in bulk, this unit serves as a precision inline module for military-grade RF applications requiring signal level reduction.

Feature Summary

• Provides precise 5 dB signal attenuation for RF circuitry
• Screened construction ensures electromagnetic interference protection
• Compatible with standard SMA male-to-female interfaces

Applications

• Satellite microwave circuit power level adjustment
• Military RF system signal conditioning
• Test and measurement equipment calibration

Procurement Notes

Verify the specific attenuation value and screening status against the manufacturer's official datasheet prior to procurement. Confirm that the SMA connector gender configuration matches the system requirements. Ensure environmental ratings meet the operational temperature constraints of the intended deployment environment.

Selection Notes

Select this component when a fixed 5 dB attenuation is required within the 12.4 GHz bandwidth. Consider the 2 W power handling capability relative to the system's maximum output levels. The screened design is suitable for environments requiring isolation from external interference.

Part Context

This part belongs to the M3933 series of RF attenuators designed for high-reliability applications. It represents a specialized interconnect solution that integrates attenuation functionality directly into the connector interface, eliminating the need for separate discrete components in the signal path.

Replacement Considerations

M3933/14-09N is a documented equivalent variant. Verify compatibility regarding screening specifications and connector gender orientation before substitution.
