PE7379-20

Overview

The Pasternack PE7379-20 is a fixed RF attenuator designed for high-power applications within the 0 Hz to 7.5 GHz frequency range. It provides a precise attenuation value of 20 dB with a characteristic impedance of 50 Ohms. The device supports a maximum power handling capacity of 25 Watts, ensuring reliable operation in demanding signal environments. Constructed with a HEX single-row module package, it features 7/16 DIN connectors for secure interfacing. This component is suitable for broadband systems requiring stable signal reduction across its specified operational bandwidth.

Feature Summary

• Provides fixed 20 dB attenuation for signal level control
• Supports continuous power handling up to 25 Watts
• Operates effectively from DC to 7.5 GHz frequency range
• Utilizes robust 7/16 DIN connector interface for secure connection

Applications

• RF test and measurement setups requiring precise signal reduction
• Broadband communication systems needing signal attenuation
• High-power RF circuit protection and level adjustment

Procurement Notes

Verify that the required attenuation value matches the system design specifications exactly. Confirm that the operating frequency range falls within the 0 Hz to 7.5 GHz limit to ensure performance integrity. Ensure the connected equipment can handle the 25 Watt power rating without damage. Check connector compatibility with existing 7/16 DIN interfaces before integration into the assembly.

Selection Notes

Select this model when a fixed 20 dB reduction is necessary for signals up to 7.5 GHz. Consider the 25 Watt power rating for high-energy RF paths. The 50 Ohm impedance must align with the rest of the transmission line components. Evaluate the physical size of the HEX module against available space constraints in the final enclosure or rack setup.

Part Context

This component belongs to the category of fixed coaxial attenuators used in radio frequency engineering. It serves as a passive device to reduce signal amplitude without introducing significant distortion. Such attenuators are critical for protecting sensitive downstream equipment from high-power sources while maintaining signal fidelity across wide bandwidths in professional RF environments.

Replacement Considerations

The Fairview Microwave SA75DFDF25W-20 is documented as a parameter-equivalent substitute. Verify mechanical fit and connector alignment when swapping between manufacturers. Ensure electrical specifications remain identical to avoid system performance degradation during replacement.
