PE7047-3

Overview

The Pasternack PE7047-3 is a fixed coaxial attenuator designed for radio frequency applications. It provides a nominal attenuation of 3 dB with a 50 Ohm impedance. The device features N-type connectors, specifically an N male connector on one side and an N female connector on the other. It operates within a frequency range of DC to 12.4 GHz and is rated for a maximum power handling of 2 Watts. The unit utilizes a passivated stainless steel body for durability.

Feature Summary

• Fixed 3 dB attenuation value
• N male to N female connector interface
• Passivated stainless steel construction
• Wideband operation up to 12.4 GHz

Applications

• RF signal level reduction in test and measurement setups
• Impedance matching in microwave circuits
• Signal conditioning in communication systems

Procurement Notes

Verify the specific datasheet version for precise VSWR and insertion loss values before integration. Confirm that the N-type connector gender configuration matches the system requirements. Ensure the operating environment remains within the specified 2 Watt power limit to prevent component damage. Check for any RoHS compliance documentation if required by local regulations.

Selection Notes

Select this model when a precise 3 dB reduction is required at frequencies extending to 12.4 GHz. The N-type interface suits standard laboratory and industrial RF infrastructure. Consider the 2 Watt power rating against peak signal levels. The stainless steel body offers robustness for repeated connection cycles compared to plated alternatives.

Part Context

This component belongs to the Pasternack PE7047 series of fixed attenuators. The series includes various attenuation values such as 6 dB, 12 dB, and 20 dB, all sharing similar mechanical and electrical characteristics. These devices are categorized under connectorized attenuators and are commonly used in RF engineering for signal management.

Replacement Considerations

Compatible substitutes include other 3 dB fixed attenuators with N-type connectors and similar power ratings. Models like the PE7323-3 offer comparable specifications. Verify that replacement units maintain the same 50 Ohm impedance and frequency range up to 12.4 GHz.
