PE7009-1

Overview

The Pasternack PE7009-1 is a fixed RF attenuator module designed for 75 Ohm impedance systems. It provides a precise attenuation value of 1 dB across a frequency range from DC to 1 GHz. The component utilizes BNC connectors, featuring a male input and female output interface. It is rated to handle up to 1 Watt of power within the specified operational limits. The housing is constructed from brass with a nickel finish, ensuring durability and signal integrity in high-frequency applications.

Feature Summary

• Provides stable 1 dB attenuation for 75 Ohm signal paths
• Operates reliably from DC frequencies up to 1 GHz
• Features robust brass construction with nickel plating
• Supports continuous power loads up to 1 Watt

Applications

• Signal level adjustment in 75 Ohm video distribution networks
• Impedance matching and loss compensation in broadcast infrastructure
• Test and measurement setups requiring precise low-level attenuation
• RF circuit design for cable television and satellite receiver systems

Procurement Notes

Verify the specific connector gender configuration matches the system requirement, as the model denotes a male-to-female arrangement. Confirm that the 75 Ohm impedance specification aligns with the existing network topology to prevent signal reflection issues. Ensure the operating environment remains within the 1 Watt power rating to maintain component longevity and performance stability during installation.

Selection Notes

Select this component when a precise 1 dB reduction is required in a 75 Ohm environment. The BNC interface suits standard coaxial connections common in video and broadcast equipment. Consider the 1 GHz frequency limit to ensure suitability for the target application bandwidth. The inline module format allows for easy integration into existing cabling runs without complex mounting requirements.

Part Context

This part belongs to Pasternack's series of fixed attenuators designed for specific impedance standards. Unlike variable attenuators, it offers a permanent, non-adjustable loss value. The 75 Ohm variant is distinct from the more common 50 Ohm versions used in general RF testing. It serves as a passive component essential for maintaining signal balance in specialized transmission lines.

Replacement Considerations

Direct substitutes must match the 1 dB attenuation value, 75 Ohm impedance, and BNC connector type. Verify that any replacement supports the same 1 Watt power rating and 1 GHz frequency range. Ensure the physical form factor allows for equivalent inline installation in the target assembly.
