PE7018-20

Overview

The PE7018-20 is a fixed RF attenuator manufactured by Pasternack. It provides a nominal attenuation of 20 dB with a frequency range extending from DC to 18 GHz. The device utilizes SMA male-to-SMA female connectors and is rated for a maximum power handling capacity of 25 Watts. The construction features an aluminum heatsink body with a black anodized finish, designed for thermal management in high-power applications.

Feature Summary

• Fixed 20 dB attenuation value
• Wideband operation up to 18 GHz
• High power handling capability of 25 Watts
• SMA connector interface configuration

Applications

• RF signal level control in test and measurement equipment
• Attenuation in microwave communication systems
• Protection of sensitive receiver inputs in high-power environments

Procurement Notes

Verify the specific datasheet version provided by the manufacturer or authorized distributor to confirm current RoHS compliance status and detailed electrical tolerances. Ensure that the SMA connector gender and mating requirements align with the system design before procurement. Cross-reference the part number with official Pasternack catalogs to avoid confusion with similar models in the PE7018 series.

Selection Notes

Select this component when a precise 20 dB reduction is required across a broad bandwidth up to 18 GHz. The 25 Watt power rating makes it suitable for high-power transmission lines where standard attenuators might fail. Consider the physical size and heatsink requirements for integration into the enclosure. Verify that the SMA interface matches the existing cabling infrastructure.

Part Context

This model belongs to the PE7018 series of fixed attenuators from Pasternack. These components are characterized by their robust aluminum construction and ability to handle significant power levels. The series typically offers various attenuation values while maintaining consistent performance characteristics across the specified frequency range.

Replacement Considerations

Direct substitutes may include other 20 dB fixed attenuators with SMA connectors and comparable power ratings. Ensure any replacement maintains the 18 GHz upper frequency limit and 25 Watt power handling. Check for mechanical compatibility regarding connector type and mounting style.
