PE7045-9

Overview

The Pasternack PE7045-9 is a fixed coaxial attenuator designed for RF applications up to 12.4 GHz. It features SMA male-to-SMA female connectors and provides a precise attenuation value of 9 dB. The unit operates at a 50 Ohm impedance with a power handling capacity of 2 Watts. Constructed with a passivated stainless steel body, it ensures durability in demanding environments. This component is suitable for signal level control in test and measurement setups.

Feature Summary

• Fixed 9 dB attenuation value
• SMA male to SMA female interface
• Passivated stainless steel construction

Applications

• RF signal level control
• Test and measurement equipment
• Communication system calibration

Procurement Notes

Verify the exact model designation against official Pasternack documentation to confirm specifications. Ensure compatibility with existing SMA interfaces. Check for RoHS compliance status if required by project standards. Confirm power ratings match system requirements before integration.

Selection Notes

Select this component when a fixed 9 dB reduction is required within the 12.4 GHz frequency range. Consider the 2W power rating for thermal management. Ensure connector gender matches the circuit design. Verify environmental operating limits if used in extreme conditions.

Part Context

This part belongs to Pasternack's series of fixed coaxial attenuators. These components are typically used to reduce signal amplitude without distortion. The PE7045 series utilizes a resistive PI pad design for consistent performance across the specified bandwidth.

Replacement Considerations

Check for direct substitutes with identical 9 dB attenuation and SMA interfaces. Verify that alternative parts meet the 12.4 GHz maximum frequency and 2W power handling requirements. Ensure mechanical dimensions and connector types are compatible.
