PE7089-4

Overview

The PE7089-4 is a fixed RF attenuator manufactured by Pasternack, designed for high-frequency applications. It provides a precise attenuation value of 4 dB across a frequency range of 0 Hz to 50 GHz. The component features a 2.4mm male-to-female connector interface and maintains a nominal impedance of 50 Ohms. It is rated for a maximum power handling capacity of 1 Watt. The unit is constructed as an in-line module with a passivated stainless steel body, ensuring durability and consistent performance in demanding microwave environments.

Feature Summary

• Fixed 4 dB attenuation design
• Operates up to 50 GHz frequency range
• 2.4mm coaxial connector interface
• Passivated stainless steel construction

Applications

• Microwave signal testing and measurement systems
• RF circuit calibration and characterization
• Signal level reduction in high-frequency transmission lines
• Laboratory equipment and instrumentation interfaces

Procurement Notes

Verify the specific model designation PE7089-4 against official Pasternack documentation to confirm the 4 dB attenuation value and 2.4mm connector type. Ensure compatibility with existing 50 Ohm system impedance requirements. Check for any specific environmental ratings or handling instructions provided in the manufacturer datasheet prior to integration into sensitive RF setups.

Selection Notes

Select this component when a precise 4 dB attenuation is required at frequencies extending up to 50 GHz. The 2.4mm interface is suitable for compact high-frequency designs where standard connectors may introduce excessive loss or parasitic effects. Consider the 1 Watt power rating to ensure it meets the signal levels present in the application path without risk of damage.

Part Context

This part belongs to the Pasternack series of 2.4mm fixed attenuators. These components are engineered for precision and reliability in microwave applications. The series offers various attenuation values while maintaining consistent electrical performance across the ultra-wide bandwidth. The PE7089-4 specifically addresses needs for moderate signal reduction in high-speed digital and analog RF systems.

Replacement Considerations

Compatible substitutes include other 4 dB fixed attenuators with 2.4mm connectors from Pasternack or equivalent manufacturers, provided they meet the 50 Ohm impedance and 50 GHz frequency specifications. Verify that alternative parts offer similar power handling capabilities and physical dimensions for direct replacement.
