PE7388-40

Overview

The PE7388-40 is a fixed 40 dB attenuator from Pasternack, featuring an in-line resistive PI pad design. It operates within a frequency range of DC to 3 GHz and maintains a 50 Ohm impedance. The unit utilizes Type N connectors, with male gender on side 1 and female gender on side 2. The housing consists of black anodized aluminum, providing a heatsink body rated for 50 Watts of power handling.

Feature Summary

• Fixed 40 dB attenuation value
• Resistive PI pad circuit topology
• Black anodized aluminum heatsink enclosure

Applications

• RF signal level reduction
• Impedance matching networks
• Test and measurement setups

Procurement Notes

Verify the specific connector genders and orientation against project requirements. Confirm that the 50 Watt power rating aligns with operational thermal conditions. Ensure the DC to 3 GHz frequency coverage meets system bandwidth needs before finalizing procurement.

Selection Notes

Select this component when a precise 40 dB loss is required at 50 Ohms. The integrated heatsink supports higher power dissipation compared to standard units. Verify compatibility with existing Type N interfaces in the RF chain.

Part Context
