PE7371-40

Overview

The PE7371-40 is a fixed 40 dB attenuator manufactured by Pasternack. It features N female connectors on both input and output sides, designed for in-line resistive PI attenuator pad applications. The component operates within a 50 Ohm impedance system and is rated to handle up to 25 Watts of power. Its frequency range extends up to 18 GHz, ensuring stable performance across microwave frequencies.

Feature Summary

• Fixed 40 dB attenuation value
• N female connector interface
• Resistive PI pad design
• Rated for 25 Watts power handling

Applications

• Microwave signal level reduction
• RF test and measurement setups
• System protection against high power levels
• Impedance matching networks

Procurement Notes

Verify the specific model number PE7371-40 matches your required attenuation and connector type. Confirm that the 25 Watt power rating and 18 GHz frequency limit align with your system's operational parameters. Ensure compatibility with existing N-type interfaces in your RF chain before finalizing procurement decisions.

Selection Notes

Select this component when a precise 40 dB reduction is needed in a 50 Ohm system. Consider the 25 Watt power handling capacity for high-power applications. The N female connectors provide standard interface compatibility. Verify that the 18 GHz upper frequency limit meets your application's bandwidth requirements.

Part Context

This part belongs to Pasternack's series of fixed coaxial attenuators. It serves as a passive RF component used to control signal strength without introducing significant distortion. The design utilizes a resistive PI network topology to achieve the specified attenuation value while maintaining impedance consistency.

Replacement Considerations

PE7371-50 is a similar fixed attenuator from the same manufacturer but provides 50 dB attenuation instead of 40 dB. Both share N female connectors and similar construction styles. Ensure the attenuation difference does not impact your system's signal budget when considering substitution.
