PE7389-20

Overview

The PE7389-20 is a fixed RF attenuator manufactured by Pasternack, designed for in-line signal reduction. It features N-type male to N-type female connectors and operates within a frequency range of 0 Hz to 3 GHz. The component provides a nominal attenuation of 20 dB with a maximum VSWR of 1.15:1. It is rated for 50 watts of power handling and maintains a 50-ohm impedance. The housing consists of black anodized aluminum with a heatsink body, supporting operation between -55°C and +125°C.

Feature Summary

• Resistive PI attenuator pad design for stable signal attenuation
• Black anodized aluminum heatsink body for thermal management
• N-type male to N-type female connector configuration

Applications

• RF signal level adjustment in test and measurement systems
• Attenuation in wireless communication infrastructure
• Signal conditioning in microwave circuit assemblies

Procurement Notes

Verify the specific part number PE7389-20 against official Pasternack documentation to confirm the 20 dB attenuation value and 50W power rating. Ensure compatibility with N-type connectors and 50-ohm system impedance requirements before integration. Check RoHS compliance status directly from the manufacturer datasheet.

Selection Notes

Select this model when a fixed 20 dB attenuation is required within a 3 GHz bandwidth. Consider the 50-watt power rating and operating temperature range of -55°C to +125°C for environmental suitability. The N-type interface must match existing system cabling and connector standards.

Part Context

This component belongs to the Pasternack PE7389 series of fixed coaxial attenuators. The series includes variants such as PE7389-10 (10 dB) and PE7389-30 (30 dB), offering different attenuation levels while sharing similar mechanical designs, connector types, and power handling capabilities up to 3 GHz.

Replacement Considerations

Compatible substitutes include other 20 dB fixed N-type attenuators from Pasternack or third-party manufacturers meeting identical electrical specifications. Verify that replacement parts maintain the same 50-ohm impedance, 50W power rating, and 3 GHz frequency limit.
