PE7394-40

Overview

The Pasternack PE7394-40 is a fixed RF attenuator module designed for inline signal reduction. It provides an attenuation value of 40 dB with a frequency range extending from 0 Hz to 4 GHz. The component features N-type connectors, specifically male on one side and female on the other, facilitating direct integration into coaxial systems. It operates at a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 50 Watts. The housing is constructed from black anodized material, ensuring durability in various deployment environments.

Feature Summary

• Provides precise 40 dB signal attenuation for RF applications
• Operates effectively across a broad frequency spectrum up to 4 GHz
• Features robust N-type male-to-female connector interface
• Supports high power handling capabilities of 50 Watts

Applications

• RF signal level adjustment in communication systems
• Test and measurement equipment calibration
• Signal conditioning in radar and electronic warfare systems

Procurement Notes

Verify the specific connector gender configuration (N Male to N Female) matches your system requirements before procurement. Confirm that the 50 Watt power rating and 4 GHz frequency limit are sufficient for your operational environment. Ensure compatibility with 50 Ohm system impedance to prevent signal reflection issues. Check for any updated datasheets regarding mechanical dimensions or mounting specifications.

Selection Notes

Select this model when a fixed 40 dB attenuation is required within the 0-4 GHz range. It is suitable for applications needing high power handling up to 50 Watts. Consider the N-type interface for standard coaxial connections. Compare against variable attenuators if adjustable signal levels are needed instead of fixed reduction.

Part Context

This component belongs to the Pasternack series of fixed RF attenuators. It shares design similarities with models like PE7394-10 and PE7394-6, which offer lower attenuation values but share the same frequency and connector specifications. These modules are typically used in conjunction with other RF components to manage signal strength in complex networks.

Replacement Considerations

Direct substitutes include other 40 dB fixed attenuators with N-type connectors and similar power ratings. Verify that alternative parts maintain the 0-4 GHz frequency range and 50 Ohm impedance. Ensure mechanical compatibility if space constraints exist.
