PE7385-40

Overview

The Pasternack PE7385-40 is a fixed RF attenuator designed for in-line module applications. It provides an attenuation value of 40 dB with a frequency range spanning from 0 Hz to 3 GHz. The component operates at a characteristic impedance of 50 Ohms and supports a maximum power rating of 100 Watts. It features N-Type connectors, specifically configured as N Male on one side and N Female on the other. The housing consists of a black anodized aluminum heatsink body, ensuring thermal management during high-power operation.

Feature Summary

• Fixed attenuation design providing consistent signal reduction
• High power handling capability rated up to 100 Watts
• Broadband frequency performance extending to 3 GHz
• Thermal management via black anodized aluminum heatsink body

Applications

• RF test and measurement instrumentation
• Telecommunications equipment signal conditioning
• General-purpose laboratory testing setups
• High-power RF circuit attenuation

Procurement Notes

Verify the specific connector gender configuration (N Male to N Female) against system requirements before ordering. Confirm that the 100 Watt power rating aligns with the operational power levels of the target application. Ensure the 50 Ohm impedance matches the surrounding RF infrastructure to maintain signal integrity. Check for any specific environmental ratings or certifications required for the intended deployment environment.

Selection Notes

Select this model when a fixed 40 dB attenuation is required within a 50 Ohm system operating up to 3 GHz. Consider the 100 Watt power rating for high-power applications where standard attenuators may overheat. The N-Type interface ensures compatibility with common RF test equipment and cabling systems. Evaluate the physical size and heatsink design if space constraints or thermal dissipation are critical factors in the installation.

Part Context

This component belongs to the Pasternack PE7385 series of fixed attenuators. Similar models in this series include PE7385-3, PE7385-10, and PE7385-20, which offer different attenuation values but share the same N Male to N Female connector configuration, 50 Ohm impedance, and 3 GHz frequency range. The series is characterized by its robust aluminum construction and high power handling capabilities.

Replacement Considerations

Direct substitutes within the same series include PE7385-3, PE7385-10, and PE7385-20, though these provide different attenuation values. Verify that any replacement maintains the 40 dB requirement. Cross-reference connector types and power ratings to ensure compatibility with existing RF chains.
