PE7003-40

Overview

The Pasternack PE7003-40 is a fixed RF attenuator designed for in-line applications within radio frequency systems. It provides a precise attenuation value of 40 dB across a frequency range extending from 0 Hz to 2 GHz. The component features TNC connectors, specifically a male connector on one side and a female connector on the other, facilitating straightforward integration into coaxial circuits. Constructed with a brass body finished in nickel plating, it ensures durability and consistent performance. The unit is rated to handle up to 1 Watt of power at the stated attenuation level, making it suitable for various signal conditioning tasks requiring stable reduction of RF energy.

Feature Summary

• Provides fixed 40 dB attenuation for signal level reduction
• Operates effectively from DC up to 2 GHz frequency range
• Features TNC male-to-female interface for direct circuit connection
• Utilizes nickel-plated brass construction for reliable performance

Applications

• RF signal path attenuation in test and measurement equipment
• Signal conditioning in communication systems operating below 2 GHz
• Integration into microwave assemblies requiring fixed loss components
• Laboratory setups for calibrating RF power levels

Procurement Notes

Verify that the required attenuation value matches the specific application needs, as this model provides a fixed 40 dB loss. Confirm compatibility with existing TNC connectors in the system design. Ensure that the maximum power handling capability of 1 Watt aligns with the operational power levels of the signal source. Check that the frequency range up to 2 GHz covers all intended operating frequencies without significant deviation in attenuation performance.

Selection Notes

Choose this component when a fixed 40 dB reduction is necessary for signals within the 0 Hz to 2 GHz spectrum. Consider the TNC interface requirements for mating connections. Evaluate if the 1 Watt power rating suffices for the expected signal strength. Assess whether the physical dimensions and mounting style fit within the available space in the assembly. Compare against variable attenuators if adjustable loss is preferred over a fixed value.

Part Context

This part belongs to the Pasternack PE7003 series of fixed attenuators, which offers various attenuation values such as 6 dB, 10 dB, 20 dB, and 30 dB. All models in this series share similar construction characteristics, including TNC connectors and a frequency range up to 2 GHz. The series is designed for general-purpose RF applications where consistent attenuation is required. The PE7003-40 specifically addresses scenarios needing higher signal reduction compared to lower-value counterparts in the same product line.

Replacement Considerations

Direct substitutes include other Pasternack models within the PE7003 series if different attenuation values are acceptable. Cross-brand replacements must match the 40 dB attenuation, TNC male-to-female configuration, 2 GHz frequency limit, and 1 Watt power rating. Verify that alternative components maintain similar VSWR specifications and physical dimensions to ensure seamless integration without redesigning the housing or connectors.
