PE7393-3

Overview

The Pasternack PE7393-3 is a fixed RF attenuator module designed for inline applications. It provides a nominal attenuation of 3 dB with a maximum operating frequency of 4 GHz. The component features SMA connectors and operates within a 50 Ohm impedance system. It supports a power rating of 25 Watts and functions across a temperature range from -65°C to +125°C.

Feature Summary

• Provides precise signal attenuation in an inline module configuration
• Supports high power handling capabilities up to 25 Watts
• Operates effectively across a broad frequency spectrum up to 4 GHz

Applications

• RF test and measurement setups requiring signal reduction
• Communication systems needing precise signal level adjustment
• Electronic equipment testing environments

Procurement Notes

Verify the specific datasheet version for the PE7393-3 to confirm mechanical dimensions and connector tolerances. Ensure that the application environment remains within the specified -65°C to +125°C operational temperature range. Confirm that the 25W power rating aligns with the system's peak power requirements to prevent component damage during operation.

Selection Notes

Select this model when a fixed 3 dB attenuation is required at frequencies up to 4 GHz. The SMA interface suits standard coaxial connections, while the 50 Ohm impedance matches typical RF systems. Consider the 25W power rating for high-power applications where signal reduction is necessary without compromising thermal performance or signal integrity.

Part Context

This component belongs to the Pasternack series of fixed RF attenuators. These modules are engineered for reliable performance in demanding RF environments. The design focuses on maintaining consistent attenuation values across the specified frequency band while supporting significant power levels for robust system integration.

Replacement Considerations

Check for compatible SMA-based attenuators offering similar 3 dB attenuation and 4 GHz frequency limits. Verify that substitute components match the 50 Ohm impedance and 25W power rating. Ensure mechanical compatibility with existing mounting configurations before finalizing any replacement decisions.
