PE7380-3

Overview

The Pasternack PE7380-3 is a fixed RF attenuator designed for high-frequency applications, offering a precise attenuation value of 3 dB. It operates within a frequency range from DC to 7.5 GHz and supports a power handling capacity of 25 Watts at the stated attenuation level. The component utilizes 7/16 DIN female connectors on both input and output ports, ensuring compatibility with standard industrial RF systems. Constructed with a black anodized aluminum heatsink body, it provides efficient thermal management and durability in demanding environments.

Feature Summary

• Fixed 3 dB attenuation performance across a wide bandwidth
• Robust 7/16 DIN female-to-female interface configuration
• High power handling capability up to 25 Watts
• Black anodized aluminum heatsink body for thermal stability

Applications

• RF signal level adjustment in microwave test setups
• Attenuation stages in communication system architectures
• Power reduction for sensitive receiver inputs
• Calibration equipment signal conditioning

Procurement Notes

Verify that the required attenuation value matches the specific 3 dB specification of the PE7380-3 model. Confirm that the operating frequency does not exceed the 7.5 GHz upper limit and that the system power levels remain within the 25 Watt rating. Ensure connector compatibility with existing 7/16 DIN female interfaces before procurement to avoid integration issues.

Selection Notes

Select this component when a precise 3 dB reduction is required for signals up to 7.5 GHz. Consider the 25 Watt power rating for high-power applications where thermal dissipation is critical. The 7/16 DIN interface is suitable for robust industrial connections. Evaluate alternative models if different attenuation values or connector types are needed for the specific application requirements.

Part Context

This part belongs to Pasternack's line of fixed RF attenuators, which provide stable signal attenuation for microwave and radio frequency systems. The series includes various attenuation values and connector configurations to support diverse engineering needs. The PE7380-3 specifically addresses applications requiring moderate signal reduction with high power handling capabilities.

Replacement Considerations

Direct substitutes include other Pasternack models with identical 3 dB attenuation, 7/16 DIN female connectors, and similar power ratings. Verify that any replacement maintains the same frequency range up to 7.5 GHz and physical interface dimensions to ensure seamless integration without mechanical modifications.
