PE7045-8

Overview

The Pasternack PE7045-8 is a fixed RF attenuator designed for high-frequency applications up to 12.4 GHz. It provides a precise attenuation value of 8 dB with a power rating of 2 Watts. The component features SMA male to SMA female connectors and utilizes a passivated stainless steel body for durability. This connectorized attenuator is part of the broader PE7045 series, offering reliable signal reduction in microwave systems.

Feature Summary

• Fixed 8 dB attenuation value
• Frequency range up to 12.4 GHz
• SMA male to SMA female interface
• Passivated stainless steel construction

Applications

• Microwave signal testing
• RF circuit calibration
• Signal level adjustment in communication systems

Procurement Notes

Verify the specific model suffix to ensure correct attenuation and connector type. Confirm frequency specifications match system requirements up to 12.4 GHz. Check RoHS compliance status if required by project standards. Ensure SMA connector gender matches existing cabling infrastructure.

Selection Notes

Select this model when a fixed 8 dB reduction is required within the 12.4 GHz bandwidth. Consider the 2 Watt power handling capability for appropriate thermal management. The SMA interface dictates compatibility with standard coaxial connections. Stainless steel housing offers environmental protection compared to plated variants.

Part Context

This component belongs to the Pasternack PE7045 series of fixed attenuators. Similar models include PE7045-2, PE7045-3, PE7045-10, and PE7045-20, which offer different attenuation values but share the same frequency range and connector style. The series is characterized by its use of passivated stainless steel bodies and SMA interfaces.

Replacement Considerations

Direct substitutes include other PE7045 series models with identical 8 dB attenuation if available. Cross-brand replacements must match SMA gender, 8 dB value, 12.4 GHz limit, and 2W power rating.
