PE7371-3

Overview

The PE7371-3 is a fixed RF attenuator manufactured by Pasternack. It provides an attenuation value of 3 dB with a frequency range of DC to 18 GHz. The device operates at 50 Ohms impedance and handles up to 25 Watts of power. It features N-type female connectors on both ends. The housing is constructed from black anodized aluminum for heat dissipation. The unit weighs approximately 362.87 grams.

Feature Summary

• Fixed 3 dB attenuation performance across the specified frequency band
• High power handling capability rated at 25 Watts
• Robust black anodized aluminum construction for thermal management
• Standard N-type female interface for seamless system integration

Applications

• RF signal level reduction in microwave test setups
• Impedance matching and isolation in high-frequency circuits
• Signal conditioning in communication systems operating up to 18 GHz
• Power monitoring and protection in transmitter chains

Procurement Notes

Verify component status as the PE7371-3 is listed as obsolete and no longer manufactured by Pasternack. Confirm availability through authorized distributors or secondary market suppliers. Ensure replacement parts meet identical electrical specifications including 3 dB attenuation, 25W power rating, and 18 GHz frequency range. Check connector compatibility and physical dimensions before procurement.

Selection Notes

Select this component when a fixed 3 dB attenuation is required within a 50 Ohm system. Ensure the application frequency does not exceed 18 GHz. Verify that the 25 Watt power rating aligns with peak signal levels. Consider the N-type female interface for mating connections. Evaluate weight and size constraints due to the substantial aluminum housing designed for thermal dissipation.

Part Context

This model belongs to Pasternack's PE7371 series of fixed attenuators. The series includes variants with different attenuation values such as PE7371-6, PE7371-20, and PE7371-30. All share similar construction materials and connector types but differ in attenuation specifications. The PE7371-3 specifically targets applications requiring moderate signal reduction.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly provided in the source data. Users should consult Pasternack for current equivalent models or verify compatible third-party attenuators meeting 3 dB, 25W, DC-18GHz, N-female specs.
