PE7394-3

Overview

The Pasternack PE7394-3 is a fixed RF attenuator designed for Type N interfaces, providing a nominal attenuation of 3 dB. It operates from DC to 4 GHz with a 50-ohm impedance and supports up to 50 watts of power. The unit features an aluminum heatsink body with black anodized finish, connecting via N male to N female ports.

Feature Summary

• Integrates a black anodized aluminum heatsink body for thermal management
• Provides fixed 3 dB attenuation across the specified frequency range
• Supports bidirectional signal flow between Type N connectors

Applications

• RF test and measurement setups requiring precise signal reduction
• Low-frequency microwave circuit design and prototyping
• Signal conditioning in communication systems operating up to 4 GHz

Procurement Notes

Verify the datasheet confirms the 4 GHz upper frequency limit and 50-watt rating. Ensure the specific model suffix matches the required 3 dB value. Confirm connector gender alignment (male-to-female) for system integration. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a fixed 3 dB loss is necessary within a 50-ohm system up to 4 GHz. The integrated heatsink allows handling 50 watts without external cooling. Compare against other values in the PE7394 series if different attenuation levels are needed.

Part Context

This part belongs to Pasternack's low-frequency RF attenuator line. It utilizes standard Type N connectors suitable for general-purpose RF applications. The design prioritizes thermal dissipation through its metal housing construction.

Replacement Considerations

Consult the manufacturer for direct substitutes within the PE7394 series. Verify that any alternative maintains the 3 dB attenuation, 50-ohm impedance, and 4 GHz frequency coverage.
