2082-6418-03

Overview

The Amphenol XMA 2082-6418-03 is an RF attenuator designed for in-line applications. It provides a fixed attenuation value of 3dB within a frequency range of 0 Hz to 18 GHz. The component operates at a nominal impedance of 50 Ohms and supports a maximum power handling capacity of 2W. It utilizes SMA connectors with a male-to-female configuration, housed in a single-row module package.

Feature Summary

• Provides fixed 3dB signal attenuation across a wide bandwidth up to 18 GHz
• Features SMA male-to-female interface for direct in-line integration
• Supports 2W power handling capability for robust RF signal management

Applications

• RF signal level adjustment in test and measurement equipment
• Attenuation stages in wireless communication systems
• Signal conditioning in high-frequency circuit boards

Procurement Notes

Verify the specific part number against manufacturer datasheets to ensure compatibility with system requirements. Confirm that the SMA connector orientation and power ratings align with the intended application environment. Check for RoHS compliance status if environmental regulations apply. Ensure storage conditions are appropriate as moisture sensitivity is not applicable.

Selection Notes

Select this component when a precise 3dB reduction is required in the 0-18 GHz spectrum. Consider the 2W power limit for thermal management in high-power circuits. The SMA interface dictates mating connector types. Verify physical dimensions for PCB or chassis mounting constraints compared to alternative attenuator models.

Part Context

This model belongs to the Amphenol XMA series of RF attenuators. It shares the same frequency range and connector type with variants like 2082-6041-06 (6dB) and 2082-6418-03-CRYO (cryogenic version). The standard industrial version differs from specialized environmental grades while maintaining core electrical specifications.

Replacement Considerations

Direct substitutes include other 3dB SMA attenuators from Amphenol XMA such as the 2082-6418-03-CRYO for cryogenic environments. Cross-brand replacements must match the 50 Ohm impedance, 18 GHz frequency limit, and 2W power rating to maintain system performance.
