PE7388-3

Overview

The PE7388-3 is a fixed attenuator manufactured by Pasternack. It provides a nominal attenuation of 3 dB with N male to N female connectors. The device operates within a frequency range of DC to 12.4 GHz and supports a maximum power rating of 50 watts. It features a black anodized aluminum heatsink body and maintains a VSWR of 1.15:1. The unit has a 50 ohm impedance and functions between -65°C and +100°C.

Feature Summary

• Unidirectional signal flow capability
• Black anodized aluminum heatsink body for thermal management
• N male to N female connector interface

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 the PE7388-3 to confirm the exact frequency range, as some sources cite up to 12.4 GHz while others may vary. Ensure the unidirectional nature aligns with your circuit design requirements. Confirm connector gender and material specifications match your system interface needs before procurement.

Selection Notes

Select this component when a precise 3 dB attenuation is required at N-type interfaces. Consider the 50-watt power handling capacity for high-power applications. The unidirectional design is critical for preventing reverse signal reflection. Verify that the operating temperature range meets your environmental conditions.

Part Context

This part belongs to Pasternack's line of fixed attenuators designed for RF and microwave applications. It serves as a passive component for controlling signal strength without introducing significant distortion. The N-type connector ensures compatibility with standard coaxial systems in laboratory and industrial environments.
