PE7021-40

Overview

The Pasternack PE7021-40 is a fixed RF attenuator designed for high-power applications. It provides a nominal attenuation of 40 dB across a frequency range from DC to 1.5 GHz. The device features N-type connectors, specifically an N male input and an N female output. It is constructed with a black anodized aluminum body that incorporates a directional heatsink design to manage thermal loads effectively. The unit is rated to handle up to 100 Watts of power at the stated attenuation value, ensuring reliable performance in demanding microwave environments.

Feature Summary

• Directional heatsink construction for enhanced thermal management
• High power handling capability rated at 100 Watts
• Robust black anodized aluminum housing

Applications

• Microwave signal testing and measurement systems
• RF power monitoring setups requiring precise signal reduction
• High-power transmission line attenuation

Procurement Notes

Verify the specific connector gender configuration matches your system requirements, as this model specifies N male to N female interfaces. Confirm that the operating frequency does not exceed the 1.5 GHz upper limit and that the power levels remain within the 100 Watt rating to ensure component longevity and performance stability.

Selection Notes

Select this model when high power dissipation is required alongside significant signal attenuation in the VHF/UHF bands. The directional heatsink design distinguishes it from standard compact attenuators, making it suitable for continuous wave applications where thermal buildup could otherwise degrade performance or damage lower-rated components.

Part Context

This component belongs to Pasternack's series of fixed coaxial attenuators utilizing N-type interfaces. It shares the same structural design philosophy as other models in the PE7021 series, such as the PE7021-20, but offers higher attenuation values. The series is characterized by its use of directional heatsinks to support high-power operations in industrial and commercial RF infrastructure.

Replacement Considerations

Direct substitutes include other 40 dB fixed attenuators with N-type connectors, such as the PE7021-40 variants from different manufacturers. Ensure replacement units maintain the 1.5 GHz frequency range and 100 Watt power rating to preserve system integrity.
