2082-6525-18-20

Overview

The Amphenol XMA 2082-6525-18-20 is a non-cryogenic RF attenuator designed for inline module applications. It provides a fixed attenuation value of 20dB with a nominal impedance of 50 Ohms. The component operates across a frequency range from DC to 18 GHz and supports a maximum power handling capacity of 25 Watts. It utilizes SMA connectors, featuring a male-to-female interface configuration.

Feature Summary

• Provides precise signal reduction through a fixed 20dB attenuation level suitable for high-power RF environments.
• Supports wideband operation extending from direct current up to 18 GHz for versatile system integration.
• Features robust SMA male-to-female connectivity ensuring reliable signal transmission within standard 50 Ohm systems.

Applications

• High-power RF test and measurement setups requiring stable signal levels
• Wireless communication infrastructure components operating at microwave frequencies
• Satellite navigation and tracking systems needing precise signal attenuation

Procurement Notes

Verify the specific connector gender configuration and power rating against your schematic requirements before ordering. Confirm that the SMA male-to-female interface matches your existing cabling or fixture standards. Ensure the 25W power handling capability exceeds your system's maximum continuous wave output to prevent component damage during operation.

Selection Notes

Select this model when a fixed 20dB reduction is required in high-power scenarios up to 25W. Consider the SMA interface compatibility with your current assembly. Evaluate if the 18 GHz upper frequency limit meets your operational bandwidth needs compared to higher-frequency alternatives like 26.5 GHz or 40 GHz variants offered by the manufacturer.

Part Context

This component belongs to the Amphenol XMA Omni Spectra series of non-cryogenic attenuators. These devices are engineered for durability in demanding electronic environments. The product line includes various attenuation values and frequency ratings, catering to diverse RF engineering requirements across multiple industrial sectors.

Replacement Considerations

For equivalent performance, consider part number 2082-6502-20 for lower power handling (10W) or 2082-6041-06 for reduced power (2W). Higher power options include 2082-6525-18-20 variants with different attenuation values if 20dB is not strictly required.
