PE7380-20

Overview

The Pasternack PE7380-20 is a fixed RF attenuator designed for high-power applications. It provides a nominal attenuation of 20 dB with a frequency range extending from 0 Hz to 7.5 GHz. The component features 7/16 DIN female connectors on both input and output ports, ensuring compatibility with standard industrial RF systems. It operates within a 50 Ohm impedance environment and is rated to handle up to 25 Watts of power. The housing utilizes black anodized aluminum for effective heat dissipation.

Feature Summary

• Fixed 20 dB attenuation value maintained across the operational bandwidth
• High power handling capability rated at 25 Watts
• Broadband performance supporting frequencies up to 7.5 GHz
• Robust black anodized aluminum heatsink body for thermal management

Applications

• RF signal level reduction in high-power transmission lines
• Test and measurement setups requiring precise attenuation up to 7.5 GHz
• Base station and wireless infrastructure signal conditioning

Procurement Notes

Verify the specific connector type and power rating against your system requirements before procurement. Ensure that the 7/16 DIN interface matches your existing cabling and equipment. Confirm that the 25W power handling capacity exceeds your maximum expected signal power to prevent damage. Check for any environmental specifications if the unit will be used in extreme conditions.

Selection Notes

Select this model when a fixed 20 dB reduction is required in a 50 Ohm system operating up to 7.5 GHz. The 7/16 DIN interface is suitable for higher power applications compared to smaller connectors like N-type or SMA. Consider the physical size and weight of the hex module form factor during installation planning. Ensure adequate spacing for heat dissipation given the 25W rating.

Part Context

This component belongs to the Pasternack PE7380 series of fixed attenuators. The series offers various attenuation values while maintaining consistent connector types and power ratings. The PE7380-20 specifically addresses the need for significant signal reduction in broadband RF environments. It complements other components in the same family by providing standardized interfaces and reliable performance characteristics.

Replacement Considerations

Direct substitutes may include other 20 dB fixed attenuators with 7/16 DIN female connectors and similar power ratings. Verify that any replacement maintains the 7.5 GHz frequency range and 50 Ohm impedance. Ensure the physical dimensions and mounting style are compatible with the existing assembly. Cross-reference datasheets for VSWR and insertion loss specifications to ensure equivalent performance.
