PE7389-10

Overview

The Pasternack PE7389-10 is a fixed RF attenuator designed for coaxial applications, providing a nominal attenuation of 10 dB. It operates within a frequency range of 0 Hz to 3 GHz and features Type N male-to-female connectors. The unit is rated for 50 Watts of power at the specified attenuation value and maintains a 50 Ohm impedance with a VSWR of 1.15:1. Constructed with a black anodized aluminum heatsink body, it supports operation between -55°C and +125°C.

Feature Summary

• Fixed attenuation design ensuring stable signal reduction without variable adjustment requirements
• Robust black anodized aluminum heatsink body for effective thermal management during high-power operation
• Type N connector interface providing reliable male-to-female interconnection in RF systems

Applications

• RF signal level control in microwave test and measurement setups
• Signal conditioning in wireless communication infrastructure
• Attenuation integration in radar system components

Procurement Notes

Verify that the specific part number PE7389-10 matches the required 10 dB attenuation value and 3 GHz frequency limit. Confirm compatibility with existing Type N connector interfaces and ensure the 50 Watt power rating aligns with system operational requirements. Check datasheet specifications for temperature range compliance.

Selection Notes

Select this component when a fixed 10 dB reduction is necessary within the 0 Hz to 3 GHz bandwidth. Ensure the application environment accommodates the -55°C to +125°C operating temperature range. Verify that the 50 Ohm impedance and 50 Watt power handling capacity meet the specific circuit demands before integration.

Part Context

This model belongs to the Pasternack PE7389 series of fixed coaxial attenuators. The series offers various attenuation values, including 3 dB and 20 dB options, all sharing similar construction standards. These components are engineered for consistent performance across microwave frequencies using durable aluminum heatsink bodies.

Replacement Considerations

Compatible substitutes include other Pasternack models within the PE7389 series offering identical 10 dB attenuation and Type N connectivity. Ensure any replacement maintains the same 3 GHz maximum frequency and 50 Watt power rating to preserve system integrity.
