PE7018-40

Overview

The Pasternack PE7018-40 is a fixed RF attenuator designed for high-frequency applications. It provides a precise attenuation value of 40 dB across a frequency range extending from DC to 18 GHz. The component features an impedance of 50 Ohms, ensuring compatibility with standard RF systems. It is rated to handle up to 25 Watts of power at the specified attenuation level. The module utilizes SMA connectors, specifically configured as SMA male to SMA female, facilitating straightforward integration into coaxial circuits.

Feature Summary

• Fixed attenuation design providing consistent signal reduction
• Wideband operation supporting frequencies up to 18 GHz
• High power handling capability rated at 25 Watts
• SMA connector interface for reliable coaxial connection

Applications

• RF test and measurement setups requiring signal reduction
• Microwave communication system signal conditioning
• Laboratory equipment input protection
• Antenna feed line power management

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may update mechanical dimensions or material specifications over time. Confirm that the SMA connector gender configuration matches the system requirements exactly. Ensure the operating environment remains within the stated thermal limits to maintain performance integrity and prevent damage to the black anodized aluminum heatsink body during continuous use.

Selection Notes

Select this model when a fixed 40 dB reduction is required in the 18 GHz bandwidth. Consider the 25 Watt power rating against peak signal levels to avoid overheating. The SMA interface dictates cable compatibility; verify mating connector standards. Compare against variable attenuators if adjustable attenuation is needed later. Evaluate physical size constraints due to the integrated heatsink design.

Part Context

This component belongs to the Pasternack PE7018 series of fixed attenuators. The series offers various attenuation values while maintaining consistent electrical characteristics and mechanical form factors. All models in this line share similar construction materials and connector types, differing primarily in their decibel ratings and corresponding internal resistive networks.

Replacement Considerations

Direct substitutes include other 40 dB fixed attenuators with SMA male-to-female interfaces and comparable 18 GHz frequency ranges. Verify power handling capabilities match or exceed 25 Watts. Check for identical impedance matching to ensure minimal reflection in the circuit.
