PE7379-3

Overview

The Pasternack PE7379-3 is a fixed 3 dB RF attenuator designed for high-power applications. It operates within a frequency range of 0 Hz to 7.5 GHz and maintains a 50 Ohm impedance. The device features 7/16 DIN male-to-female connectors and is rated for 25 Watts of power handling. Constructed as an in-line resistive PI pad, it utilizes a HEX single-row module package. This component provides stable attenuation performance across its specified bandwidth for microwave systems.

Feature Summary

• In-line resistive PI attenuator pad design for signal reduction
• High power handling capability rated at 25 Watts
• Broadband operation extending from DC to 7.5 GHz
• Robust HEX single-row module construction

Applications

• Microwave test and measurement setups
• RF signal level adjustment in communication systems
• Laboratory equipment requiring precise attenuation
• High-power RF circuit protection

Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as the model indicates male-to-female interfaces. Confirm that the 25 Watt power rating aligns with the maximum expected signal levels in the application. Ensure the operating frequency does not exceed the 7.5 GHz upper limit. Check for any environmental certifications or material compliance documentation required for the specific deployment context.

Selection Notes

Select this component when a fixed 3 dB attenuation value is required for high-power RF signals up to 7.5 GHz. The 50 Ohm impedance ensures compatibility with standard coaxial systems. Consider the physical dimensions of the HEX module for space-constrained installations. Evaluate the thermal management capabilities if continuous full-power operation is anticipated.

Part Context

The PE7379-3 belongs to Pasternack's series of fixed attenuators utilizing 7/16 DIN connectors. These components are engineered for durability and consistent performance in demanding RF environments. The series offers various attenuation values while maintaining similar form factors and power ratings, allowing for standardized integration into microwave infrastructure.

Replacement Considerations

Fairview Microwave SA75DFDF25W-03 is a parameter-equivalent substitute. Verify connector polarity and exact attenuation tolerance before substitution.
