2082-7550-18-10

Overview

The Amphenol XMA 2082-7550-18-10 is an in-line RF attenuator module designed for high-frequency signal control. It provides a fixed attenuation value of 10 dB across a frequency range of 0 Hz to 18 GHz. The component operates with a characteristic impedance of 50 Ohms and supports a maximum power rating of 50 Watts. It utilizes SMA connectors, featuring a male-to-female interface configuration. This model is part of the XMA series, engineered for reliable performance in microwave applications requiring precise signal level adjustment within specified electrical parameters.

Feature Summary

• Provides fixed 10 dB attenuation for consistent signal reduction
• Operates effectively from DC up to 18 GHz frequency range
• Supports high power handling up to 50 Watts
• Features SMA male-to-female connector interface

Applications

• RF signal path attenuation in test and measurement equipment
• Microwave system power level control
• Communication system signal conditioning
• Radar system component integration

Procurement Notes

Verify the specific datasheet version for detailed mechanical dimensions and environmental ratings before integration. Confirm that the SMA connector gender matches the system requirements, as this model specifies a male-to-female configuration. Ensure the operating environment stays within the 50 Watt power limit to prevent damage. Check for RoHS compliance status if required by project specifications. Cross-reference the part number with official manufacturer catalogs to confirm current production status and availability.

Selection Notes

Select this component when a fixed 10 dB attenuation is required at frequencies up to 18 GHz. Consider the 50 Watt power rating for high-power applications compared to lower-rated alternatives. The SMA interface dictates compatibility with existing SMA-based cabling and systems. Evaluate the in-line module form factor against board-mounted or flanged options based on space constraints. Ensure the 50 Ohm impedance matches the system design to minimize reflections.

Part Context

This part belongs to the Amphenol XMA line of RF and microwave components, which focuses on signal control solutions. The series includes various attenuators, adapters, and switches designed for frequencies extending beyond 65 GHz. The 2082-7550-18-10 represents a standard in-line module variant, distinct from adjustable or step attenuators. It is categorized under connectorized attenuators, emphasizing its ready-to-use nature for direct circuit insertion without additional assembly.

Replacement Considerations

Direct substitutes must match the 10 dB attenuation, 18 GHz frequency range, 50 Ohm impedance, and 50 Watt power rating. Verify that replacement parts utilize compatible SMA male-to-female interfaces. Alternative models from other manufacturers may require adapter usage if connector types differ. Ensure any substitute maintains similar VSWR and insertion loss characteristics for equivalent performance.
