PE7388-20

Overview

The Pasternack PE7388-20 is a fixed attenuator rated for 20 dB attenuation with N-type male to N-type female connectors. It operates from DC to 3 GHz and handles up to 50W power. The unit features a black anodized aluminum heatsink body designed for thermal management.

Feature Summary

• Unidirectional signal flow capability
• Black anodized aluminum heatsink body construction
• N-type male to N-type female connector configuration

Applications

• RF test and measurement setups
• Signal level reduction in communication systems
• Impedance matching networks requiring fixed attenuation

Procurement Notes

Verify the specific connector gender orientation (male-to-female) against system requirements. Confirm the 50W power rating aligns with operational limits. Ensure the 3 GHz frequency range meets application bandwidth needs. Check datasheet for VSWR specifications if critical performance is required.

Selection Notes

Select this model when unidirectional attenuation is necessary. The heatsink design supports higher power dissipation compared to standard bodies. Verify compatibility with N-type mating hardware. Consider the physical size constraints of the heatsink enclosure during integration.

Part Context

This component belongs to Pasternack's fixed attenuator series. It provides precise signal reduction without active components. The N-type interface ensures broad compatibility with standard RF infrastructure. The design prioritizes thermal stability and mechanical durability.

Replacement Considerations

PE7048-20 offers similar attenuation but may differ in connector gender or frequency range. PE7388-20 is the direct part number reference. Verify exact electrical parameters before substitution.
