M3933/16-18S

Overview

The M3933/16-18S is an RF attenuator manufactured by Amphenol SV Microwave, designed for high-frequency signal management. It operates within a frequency range of 0 Hz to 18 GHz and maintains a characteristic impedance of 50 Ohms. The component provides a fixed attenuation value of 1.5 dB. It features SMA female-to-male connectors and supports a maximum power rating of 2 W. The unit is constructed as an in-line module suitable for bulk packaging.

Feature Summary

• Provides precise signal attenuation with a fixed 1.5 dB reduction value
• Supports wideband operation from DC up to 18 GHz
• Features robust SMA male and female connector interfaces
• Designed for reliable performance under specified power loads

Applications

• RF test and measurement equipment signal conditioning
• Military and aerospace communication systems
• High-frequency circuit protection and level adjustment
• Wireless infrastructure component integration

Procurement Notes

Verify the specific part number M3933/16-18S against official Amphenol SV Microwave documentation to confirm the 1.5 dB attenuation specification and SMA interface configuration. Ensure compatibility with system impedance requirements of 50 Ohms. Check for any updated screening or environmental compliance data directly from the manufacturer's current datasheets before finalizing procurement decisions.

Selection Notes

Select this component when a low attenuation value of 1.5 dB is required within the 18 GHz bandwidth. Confirm that the SMA gender combination matches the system interconnect needs. Evaluate the 2 W power handling capability against peak signal levels. Consider the MIL-Spec nature of the series if environmental ruggedness is a primary design constraint.

Part Context

This model belongs to the M3933 series of RF attenuators produced by Amphenol SV Microwave. The series includes various configurations with different attenuation values and connector types, all adhering to military specifications. The M3933/16 variant specifically utilizes SMA connectors, distinguishing it from other series members that may use 2.92mm or other interfaces.

Replacement Considerations

M3933/16-18N is listed as a parameter-equivalent substitute. Verify mechanical and electrical equivalence before substitution.
