PE7048-2

Overview

The Pasternack PE7048-2 is a fixed RF attenuator designed for in-line applications. It provides a nominal attenuation of 2 dB with a frequency range extending from DC to 12.4 GHz. The component features N-type connectors, specifically male on one side and female on the other, ensuring compatibility with standard coaxial systems. It is rated for a maximum power handling capacity of 10 Watts at the stated attenuation value. The housing is constructed from aluminum with a black anodized finish, serving as a heatsink to manage thermal loads during operation.

Feature Summary

• Fixed attenuation value of 2 dB for precise signal level reduction
• Operational frequency range up to 12.4 GHz for microwave applications
• N-type male to N-female connector configuration for direct integration
• Aluminum heatsink body with black anodized finish for thermal management

Applications

• RF signal calibration and testing setups
• Microwave communication system power adjustment
• Laboratory measurement equipment interconnects
• Base station and wireless infrastructure signal conditioning

Procurement Notes

Verify the specific connector gender configuration (Male-to-Female) against system requirements before ordering. Confirm that the 10 Watt power rating aligns with the maximum expected signal levels in the application path. Ensure the operating frequency does not exceed 12.4 GHz to maintain specified attenuation accuracy. Check for any specific environmental ratings if the deployment involves extreme temperatures or harsh conditions.

Selection Notes

Select this model when a precise 2 dB reduction is required within a broadband microwave environment. The N-type interface suits larger coaxial systems compared to SMA or SMB variants. Consider the 10 Watt power handling capability for high-power transmission lines. The heatsink design supports continuous operation without excessive temperature rise, making it suitable for permanent installations rather than temporary patch cables.

Part Context

This component belongs to the Pasternack PE7048 series of fixed attenuators. The series offers various attenuation values, including 1 dB, 10 dB, 20 dB, and 30 dB options, all sharing similar physical construction and performance characteristics. These parts are standardized for use in general-purpose RF engineering tasks where predictable signal loss is necessary for impedance matching or level control.

Replacement Considerations

Compatible substitutes include other manufacturers' 2 dB N-type fixed attenuators rated for 12.4 GHz and 10 Watts. Ensure mechanical dimensions and connector torque specifications match existing mounting hardware. Verify that alternative parts meet the same VSWR and attenuation tolerance standards to prevent signal integrity issues in critical paths.
