PE7045-3

Overview

The Pasternack PE7045-3 is a fixed RF attenuator designed for high-frequency applications. It provides a precise attenuation value of 3 dB with a maximum operating frequency of 12.4 GHz. The component features SMA male to SMA female connectors and is rated for 2 Watts of power at the stated attenuation level. The housing is constructed from passivated stainless steel, ensuring durability in demanding environments.

Feature Summary

• Fixed 3 dB attenuation value
• SMA male to SMA female interface
• Passivated stainless steel body

Applications

• Microwave signal conditioning
• RF test and measurement setups
• Signal level adjustment in high-frequency circuits

Procurement Notes

Verify the specific datasheet version for detailed electrical parameters such as VSWR and insertion loss. Confirm connector gender and impedance matching requirements against system specifications. Ensure power handling capabilities align with operational limits to prevent component damage.

Selection Notes

Select this model when a fixed 3 dB reduction is required up to 12.4 GHz. The SMA interface suits standard microwave interconnects. Consider the 2W power rating for thermal management in continuous wave applications.

Part Context

This component belongs to Pasternack's line of connectorized attenuators. It serves as a passive device for controlling signal amplitude in RF systems. The fixed nature distinguishes it from variable step or continuously adjustable attenuators.

Replacement Considerations

Check for compatible SMA interfaces and identical 3 dB attenuation values. Verify frequency range coverage up to 12.4 GHz and power handling ratings. Ensure mechanical compatibility with existing mounting structures.
