PE7049-30

Overview

The PE7049-30 is a fixed coaxial attenuator manufactured by Pasternack. It provides a nominal attenuation of 30 dB with an impedance of 50 Ohms. The device features BNC male and BNC female connectors for interconnection. Constructed from brass with a nickel plating, the body is designed for durability. It is rated to handle up to 2 Watts of power and operates effectively up to a frequency of 4 GHz.

Feature Summary

• Fixed 30 dB attenuation value
• 50 Ohm impedance design
• BNC male to BNC female connector interface
• Brass nickel plated construction

Applications

• RF signal level reduction in test setups
• Impedance matching in 50 Ohm systems
• Protection of sensitive RF measurement equipment
• Signal conditioning in communication circuits

Procurement Notes

Verify the specific datasheet version when ordering, as historical records indicate variations in connector types for similar model numbers. Confirm that the required configuration matches the BNC male to BNC female specification rather than N-type variants. Ensure the application power does not exceed the 2 Watt rating and frequency stays within the 4 GHz limit to maintain performance integrity.

Selection Notes

Select this component when a precise 30 dB reduction is required at lower frequencies up to 4 GHz. The BNC interface makes it suitable for benchtop applications or legacy systems utilizing these connectors. Consider thermal management if continuous operation near the 2 Watt power limit is necessary due to the brass body construction.

Part Context

This part belongs to Pasternack's line of fixed coaxial attenuators. It serves as a passive component for managing signal strength in radio frequency environments. The product utilizes standard BNC interfaces, distinguishing it from higher-frequency models that employ N-type or SMA connectors. It is designed for general-purpose RF testing and signal distribution tasks.

Replacement Considerations

Direct substitutes include other 30 dB fixed attenuators with BNC male-to-female interfaces. Verify that replacement units match the 50 Ohm impedance and 2 Watt power rating. Cross-reference with Pasternack series such as PE7049-3 or generic equivalents ensuring identical connector gender and frequency range compatibility.
