M3933/16-18N

Overview

The M3933/16-18N is a coaxial attenuator manufactured by Amphenol SV Microwave, designed for high-frequency applications. It operates within a frequency range of 0 Hz to 18 GHz and maintains a characteristic impedance of 50 Ohms. The device provides an attenuation value of 1.5 dB with a maximum power rating of 2 W. It features SMA connectors on both sides, configured as a jack (female) to plug (male) inline module. The component is built to withstand operating temperatures ranging from -65 °C to +165 °C.

Feature Summary

• Provides precise 1.5 dB signal attenuation in the RF spectrum up to 18 GHz
• Constructs a robust inline module using SMA connector interfaces
• Supports continuous power handling of 2 W under specified conditions

Applications

• RF test and measurement instrumentation requiring signal reduction
• Military and aerospace communication systems adhering to MIL-Spec standards
• High-frequency circuit protection and level adjustment modules

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm gender configuration and screening status. Ensure that the required attenuation tolerance and power rating align with system design specifications before ordering. Confirm environmental compliance requirements such as RoHS or REACH status directly with the supplier or datasheet.

Selection Notes

Select this component when a low attenuation value of 1.5 dB is required at frequencies up to 18 GHz. Consider the 50 Ohm impedance match for compatibility with standard RF transmission lines. Evaluate the thermal management capabilities given the 2 W power rating and wide temperature range. Compare against other M3933 series variants if different attenuation levels or connector genders are needed.
