PE7389-30

Overview

The Pasternack PE7389-30 is a fixed 30 dB RF attenuator designed for in-line applications. It features N-type male to N-type female connectors and operates within a frequency range of 0 Hz to 3 GHz. The unit maintains a 50 Ohm impedance with a VSWR of 1.15:1. Constructed with a black anodized aluminum heatsink body, it supports a power rating of 50 Watts. The component functions reliably across temperatures from -55°C to +125°C.

Feature Summary

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

Applications

• RF signal attenuation in test and measurement setups
• Signal level adjustment in communication systems
• Impedance matching in 50 Ohm coaxial circuits

Procurement Notes

Verify the specific part number PE7389-30 against official Pasternack documentation to confirm the 30 dB attenuation value and N-type connector gender. Ensure the required power rating of 50 Watts and frequency range up to 3 GHz align with system requirements. Check RoHS compliance status directly from the manufacturer datasheet before procurement.

Selection Notes

Select this component when a fixed 30 dB reduction is required in a 50 Ohm system operating up to 3 GHz. The heatsink body design indicates suitability for higher power handling compared to standard plastic-bodied attenuators. Confirm that N-type connectors match the existing cable or fixture interface requirements.

Part Context

This model belongs to Pasternack's series of fixed coaxial attenuators. Similar variants exist with different attenuation values such as 3 dB, 6 dB, and 10 dB, sharing the same physical form factor and connector types. The PE7389 series utilizes a standardized heatsink design for consistent thermal performance across the product line.

Replacement Considerations

Direct substitutes include other Pasternack models with identical electrical specifications, such as the PE7389-30 from alternative distributors. Cross-manufacturer replacements must match the 30 dB attenuation, N-type connectors, 50 Ohm impedance, and 3 GHz frequency limit.
