2082-6502-20

Overview

The Amphenol XMA 2082-6502-20 is a fixed RF attenuator designed for signal control in high-frequency applications. It provides a nominal attenuation of 20dB across a frequency range of 0 Hz to 18 GHz. The component operates with a 50 Ohm impedance and supports a power rating of 10W. It utilizes SMA connectors in an inline module configuration, featuring male and female interfaces. The unit has a length of 50 mm and weighs 9 grams, with a VSWR of 1.40:1.

Feature Summary

• Provides precise 20dB signal attenuation for RF circuit management
• Operates effectively from DC up to 18 GHz frequency range
• Supports high power handling capacity of 10 Watts
• Features low VSWR of 1.40:1 for efficient signal transmission

Applications

• RF test and measurement equipment signal conditioning
• Microwave communication system power level adjustment
• High-frequency circuit protection and isolation
• Laboratory instrumentation signal attenuation

Procurement Notes

Verify the specific SMA connector gender configuration (Male/Female) against schematic requirements before integration. Confirm that the 10W power rating aligns with peak operational loads to prevent thermal damage. Ensure the 50mm physical dimensions fit within the designated enclosure space. Check RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this model when a fixed 20dB attenuation is required at frequencies up to 18 GHz. Consider the 10W power handling capability for high-power signal paths. The SMA interface dictates compatibility with existing connector standards. Evaluate the 1.40:1 VSWR specification for applications requiring minimal signal reflection and high fidelity transmission performance.
