PE7387-40

Overview

The Pasternack PE7387-40 is a fixed RF attenuator designed for high-power applications. It features Type N male-to-female connectors and provides a nominal attenuation of 40 dB across a frequency range of DC to 3 GHz. The unit is rated for 200 watts of power handling capacity. It utilizes a black anodized aluminum heatsink body to ensure thermal stability during operation.

Feature Summary

• Unidirectional signal attenuation capability
• High power handling with integrated heatsink design
• Robust Type N connector interface

Applications

• RF test and measurement setups requiring precise signal reduction
• High-power transmitter output stages
• Antenna system protection circuits

Procurement Notes

Verify the specific datasheet version for the PE7387-40 to confirm the exact power rating and frequency limits, as manufacturer documentation may vary. Ensure that the unidirectional nature of the component aligns with the intended signal flow in the circuit design before finalizing procurement.

Selection Notes

Select this model when a 40 dB attenuation value is required within the 3 GHz bandwidth. The 200-watt rating makes it suitable for high-power environments where standard attenuators might fail. Confirm that the Type N connector gender matches the system requirements for both input and output connections.

Part Context

This component belongs to Pasternack's line of fixed attenuators, which are used to reduce signal strength without impedance mismatch. The PE7387 series specifically targets high-power applications, distinguishing itself from lower-power variants by its enhanced thermal management capabilities and robust construction materials.

Replacement Considerations

The PE7389-40 is a documented alternative offering bidirectional functionality. Verify if the unidirectional specification of the PE7387-40 is critical; if bidirectional use is needed, the PE7389-40 may be a suitable substitute.
