PE7379-40

Overview

The Pasternack PE7379-40 is a fixed RF attenuator rated at 40 dB attenuation. It operates within a frequency range of 0 Hz to 7.5 GHz and features a nominal impedance of 50 Ohms. The device handles an average power of 25 Watts and utilizes a HEX single-row module configuration with 7/16 DIN connectors.

Feature Summary

• Provides precise 40 dB signal attenuation for RF applications
• Operates across a wide frequency spectrum from DC to 7.5 GHz
• Features a robust HEX single-row module design for thermal management

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching and protection in communication systems
• Attenuation requirements in high-frequency circuit testing

Procurement Notes

Verify the specific connector gender and mating interface compatibility before integration. Confirm that the 25W average power rating meets the operational requirements of the target RF chain. Ensure the 7.5 GHz upper frequency limit aligns with the system's maximum operating frequency to maintain specified attenuation accuracy.

Selection Notes

Select this component when a fixed 40 dB attenuation value is required up to 7.5 GHz. Consider the 25W power handling capacity relative to the expected signal levels. The 7/16 DIN interface dictates the necessary cabling or adapter infrastructure for system integration.
