PE7047-9

Overview

The Pasternack PE7047-9 is a fixed RF attenuator designed for signal level reduction in microwave systems. It provides a nominal attenuation of 9 dB with a frequency range extending from DC to 12.4 GHz. The device features N-type connectors, specifically an N male connector on one side and an N female connector on the other, ensuring compatibility with standard coaxial infrastructure. It is rated for a maximum power handling capacity of 2 Watts at the stated attenuation value. The unit utilizes a passivated stainless steel body for durability and environmental resistance.

Feature Summary

• Fixed 9 dB attenuation performance across a wide bandwidth
• N male to N female connector configuration for direct integration
• Passivated stainless steel housing for mechanical robustness
• Rated for 2 Watts continuous power operation

Applications

• RF test and measurement setups requiring precise signal reduction
• Microwave communication system signal conditioning
• Laboratory equipment input protection and level adjustment
• Antenna feed line attenuation applications

Procurement Notes

Verify the specific model suffix against official Pasternack documentation to confirm the exact attenuation value and connector gender combination. Ensure that the required power rating of 2 Watts aligns with your system's operational limits. Confirm that the frequency range up to 12.4 GHz meets your application requirements. Check for any specific environmental or RoHS compliance details in the manufacturer datasheet before finalizing procurement.

Selection Notes

Select this component when a fixed 9 dB reduction is required within the DC to 12.4 GHz spectrum. The N-type interface makes it suitable for general-purpose microwave interconnects where variable attenuation is not needed. Consider the 2 Watt power limit to ensure safe operation under peak load conditions. The stainless steel construction offers advantages in environments requiring corrosion resistance and physical durability compared to plated alternatives.

Part Context

This part belongs to the Pasternack PE7047 series of fixed attenuators. The series includes various attenuation values such as 6 dB, 7 dB, 12 dB, and 20 dB, all sharing similar N-type connector configurations and power ratings. These components are categorized under RF Variable Attenuators in some catalogs but function as fixed attenuators. The series is designed for reliable performance in high-frequency applications requiring stable impedance matching.

Replacement Considerations

Direct substitutes include other models in the PE7047 series with different attenuation values if the specific dB loss can be adjusted elsewhere. Generic N-type fixed attenuators from other manufacturers may serve as replacements if they match the 9 dB specification, 12.4 GHz frequency range, and 2 Watt power rating. Verify connector gender and body material compatibility during substitution.
