PE7391-2

Overview

The PE7391-2 is a fixed RF attenuator manufactured by Pasternack. It provides a nominal attenuation of 2 dB. The device operates from DC to 3 GHz. It features SMA male connectors on both input and output ports. The unit is rated for a maximum power handling of 5 Watts. The housing is constructed from aluminum with a black anodized finish.

Feature Summary

• Fixed 2 dB attenuation value
• SMA male to SMA female interface
• Aluminum heatsink body
• DC to 3 GHz frequency range

Applications

• RF signal level reduction
• Impedance matching in test setups
• Signal conditioning in communication systems

Procurement Notes

Verify the specific part number against official Pasternack documentation to confirm the 2 dB attenuation rating and SMA connector gender. Ensure the application environment remains within the specified 5 Watt power limit and 3 GHz frequency cap. Check datasheets for precise VSWR and return loss values required for system integration.

Selection Notes

Select this component when a low attenuation value of 2 dB is required at frequencies up to 3 GHz. The SMA interface suits standard laboratory and field equipment. Consider the 5 Watt power rating for high-power applications. Aluminum construction aids thermal management compared to plastic alternatives.

Part Context

This model belongs to the PE7391 series of fixed attenuators from Pasternack. The series includes variants with different attenuation values such as 3, 6, 10, and 20 dB. All units in this line share similar physical dimensions and connector types, differing primarily in their internal resistive network design to achieve specific dB losses.

Replacement Considerations

Compatible substitutes include other 2 dB fixed attenuators with SMA male-female interfaces and comparable power ratings. Verify that alternative parts meet the DC to 3 GHz operational bandwidth and 50 Ohm impedance requirements to maintain system performance.
