PE7019-40

Overview

The Pasternack PE7019-40 is a fixed RF attenuator designed for in-line applications. It provides an attenuation value of 40 dB across a frequency range of 0 Hz to 18 GHz. The component operates with a characteristic impedance of 50 Ohms and supports a maximum power rating of 50 Watts at the stated attenuation level. It features N-Type connectors, specifically N Male input and N Female output interfaces.

Feature Summary

• Utilizes a resistive PI attenuator pad design for signal reduction
• Constructed with a directional black anodized aluminum heatsink body
• Provides fixed attenuation without variable adjustment capabilities

Applications

• RF signal level reduction in microwave systems
• Impedance matching between 50 Ohm components
• Signal conditioning in test and measurement equipment

Procurement Notes

Verify the specific connector gender configuration (N Male to N Female) against system requirements before procurement. Confirm that the 50 Watt power rating aligns with peak operational loads. Ensure the 18 GHz frequency limit covers the intended application spectrum. Check datasheet revisions for any updates to mechanical dimensions or material specifications.

Selection Notes

Select this model when a fixed 40 dB loss is required within the DC to 18 GHz band. Consider the N-Type interface compatibility with existing cabling infrastructure. Evaluate the thermal management needs given the aluminum heatsink construction. Compare against other series if variable attenuation or different connector types are necessary.

Part Context

This component belongs to the Pasternack PE7019 series of fixed attenuators. The series offers various attenuation values while maintaining consistent 50 Ohm impedance and N-Type connectivity. The PE7019-40 specifically addresses high-loss requirements up to 18 GHz.

Replacement Considerations

PE7019-20: Provides 20 dB attenuation with identical connectors and power ratings. PE7019-30: Offers 30 dB attenuation with similar physical and electrical characteristics.
