3082-7550-18-20

Overview

The Amphenol XMA 3082-7550-18-20 is an N-type in-line RF attenuator module designed for high-power applications. It provides a fixed attenuation of 20dB with a frequency range extending from DC to 18 GHz. The component features a 50 Ohm impedance and supports a maximum power handling capacity of 50 Watts. Constructed as a single-row module, it utilizes male-to-female N-type connectors for seamless integration into coaxial transmission lines.

Feature Summary

• Provides precise signal reduction via fixed 20dB attenuation
• Supports high-power operation up to 50 Watts
• Operates effectively across a broad DC to 18 GHz bandwidth
• Features robust N-type male-to-female interconnects

Applications

• RF test and measurement instrumentation
• Wireless communication base stations
• Satellite ground station equipment
• High-power radar systems

Procurement Notes

Verify the specific datasheet revision and mechanical drawings directly with Amphenol or authorized distributors before finalizing designs. Confirm that the 50W power rating aligns with your system's thermal management capabilities at the target frequencies. Ensure connector compatibility with existing N-type fixtures. Request current availability status due to potential supply chain fluctuations affecting lead times.

Selection Notes

Select this model when a fixed 20dB loss is required within the 18 GHz spectrum. Compare against other variants like the 30dB or 40dB versions if different attenuation levels are needed. Consider the 50W power limit relative to peak signal strengths. Evaluate alternative connector types if N-type interfaces do not match the system architecture.

Part Context

This component belongs to the Amphenol XMA series of connectorized attenuators. These modules are engineered for reliability in demanding RF environments. The product line typically includes various attenuation values and power ratings to suit diverse application requirements while maintaining consistent impedance and performance characteristics.

Replacement Considerations

Direct substitutes include the 3082-7550-18-30 (30dB) and 3082-7550-18-40 (40dB) models from the same manufacturer. Verify that any replacement maintains the 50W power handling and 18 GHz frequency range specifications.
