PE7385-20

Overview

The Pasternack PE7385-20 is a fixed coaxial attenuator designed for RF applications. It provides a nominal attenuation of 20 dB with a frequency range from 0 Hz to 3 GHz. The device features N-Type connectors, specifically male on one side and female on the other. It is rated for a maximum power handling capacity of 100 Watts and maintains a 50 Ohm impedance. The housing is constructed from black anodized aluminum to serve as a heatsink.

Feature Summary

• Fixed attenuation value of 20 dB
• Operates within a frequency range up to 3 GHz
• N-Type male to N-Type female interface configuration
• Black anodized aluminum heatsink body construction

Applications

• General-purpose test and measurement instrumentation
• Telecommunications equipment signal conditioning
• RF circuit power level reduction

Procurement Notes

Verify the specific connector gender orientation (Male-to-Female) matches system requirements. Confirm that the 100W power rating and 3 GHz frequency limit align with operational parameters. Ensure the N-Type interface compatibility with existing cabling infrastructure before integration.

Selection Notes

Select this component when a precise 20 dB reduction is required in high-power RF environments. The N-Type interface suits robust connections, while the aluminum body aids thermal management. Consider adjacent models like PE7385-10 or PE7385-40 if different attenuation values are needed for the same form factor.

Part Context

This part belongs to the Pasternack PE7385 series of fixed coaxial attenuators. The series offers various attenuation steps, including 3, 6, 10, 20, 30, and 40 dB options. All variants share similar physical characteristics, including the N-Type connector interface and 100W power rating, differing primarily in their attenuation specifications.

Replacement Considerations

Compatible substitutes include other Pasternack PE7385 series units with identical attenuation, such as PE7385-20 equivalents from authorized distributors. Cross-brand replacements must match the N-Type interface, 50 Ohm impedance, and 3 GHz frequency range.
