PE7039-3

Overview

The PE7039-3 is a fixed coaxial attenuator manufactured by Pasternack. It provides a nominal attenuation value of 3 dB with an accuracy of ±0.5 dB. The device operates over a frequency range from DC to 7.5 GHz and maintains a characteristic impedance of 50 Ohms. It features a 7/16 DIN Male connector on one end and a 7/16 DIN Female connector on the other. The unit is rated for a maximum input power of 5 Watts. The body is constructed from brass with a tri-metal finish, ensuring durability in RF applications.

Feature Summary

• Fixed 3 dB attenuation performance
• Operates up to 7.5 GHz frequency range
• 5 Watt maximum power rating
• Brass tri-metal body construction

Applications

• RF signal level adjustment
• Test and measurement setups
• Communication system integration

Procurement Notes

Verify the specific datasheet version for the PE7039-3 to confirm current manufacturing status and detailed electrical tolerances. Ensure that the 7/16 DIN connector compatibility matches the existing system infrastructure before procurement. Check for any RoHS compliance documentation if required for the specific project standards.

Selection Notes

Select this component when a precise 3 dB reduction is required within the 7.5 GHz bandwidth. The 5W power handling capability suits moderate power levels. The brass tri-metal body offers robust mechanical stability. Consider the 7/16 DIN interface requirements against available system connectors.

Part Context

This model belongs to the Pasternack PE7039 series of fixed attenuators. The series includes various attenuation values such as 1 dB, 6 dB, and 10 dB options. All units in this family share similar physical dimensions and connector types, differing primarily in their internal resistive networks and resulting attenuation specifications.

Replacement Considerations

Compatible substitutes include the PE7039-1 (1 dB) and PE7039-6 (6 dB) from the same manufacturer. Other manufacturers offering 7/16 DIN fixed attenuators with 3 dB loss and 5W rating may serve as alternatives, provided frequency and power specs align.
