PE7389-15

Overview

The Pasternack PE7389-15 is a fixed 15 dB attenuator designed for coaxial applications. It features an in-line, resistive PI attenuator pad configuration with a 50 Ohm impedance. The unit utilizes Type N connectors, specifically male on one side and female on the other. The housing consists of black anodized aluminum, serving as a heatsink body rated for 50 Watts of power handling. The device operates effectively from DC up to 3 GHz.

Feature Summary

• Fixed 15 dB attenuation value provided by a resistive PI pad design
• Black anodized aluminum heatsink body for thermal management
• Type N male to Type N female connector interface
• Rated for 50 Watts power handling capability

Applications

• RF signal level reduction in coaxial systems
• Impedance matching between circuit stages
• Signal conditioning within frequency ranges up to 3 GHz
• High-power RF test and measurement setups

Procurement Notes

Verify the specific connector gender orientation (male-to-female) against system requirements before ordering. Confirm that the 50 Watt power rating aligns with the maximum expected signal levels in the application. Ensure the operating frequency does not exceed the 3 GHz upper limit specified for this model. Check for any required calibration or tolerance specifications if precise attenuation values are critical for the intended use case.

Selection Notes

Choose this component when a fixed 15 dB loss is required in a 50 Ohm system. The black anodized aluminum construction supports high power dissipation up to 50 Watts. The Type N interface ensures compatibility with standard coaxial infrastructure. Consider the 3 GHz frequency limit to ensure suitability for the target RF environment. This model provides a robust solution for stable attenuation without variable adjustment needs.

Part Context

The PE7389-15 belongs to the Pasternack PE7389 series of fixed attenuators. This series includes various attenuation values such as 6, 10, 20, 30, and 40 dB options. All models in this line share similar physical characteristics, including the black anodized aluminum heatsink body and Type N connectors. They are designed for consistent performance across the DC to 3 GHz frequency range.

Replacement Considerations

Compatible substitutes include other Pasternack PE7389 series models with different attenuation values if the dB requirement changes. Generic replacements must match the 50 Ohm impedance, Type N male-to-female interface, and 3 GHz frequency limit. Ensure any alternative component meets or exceeds the 50 Watt power handling specification.
