PE8721

Overview

The Pasternack PE8721 is a five-section low-pass filter module designed for radio frequency applications. It features SMA female connectors and operates from DC to 2 GHz with a 2 GHz passband. The component has a maximum insertion loss of 1 dB, an impedance of 50 Ohms, and an input maximum VSWR of 1.5:1. It supports a maximum power handling capacity of 10 Watts.

Feature Summary

• Five-section low-pass filter design
• SMA female connector interface
• DC to 2 GHz operating range

Applications

• RF signal conditioning
• High-frequency signal attenuation
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version and connector orientation upon ordering. Confirm that the 50 Ohm impedance and 10 Watt power rating align with your system requirements. Ensure SMA female compatibility with mating components. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this model when a sharp cutoff below 2 GHz is required. The five-section architecture provides superior rejection compared to simpler designs. Ensure the 10 Watt power limit is sufficient for your application. Verify that the SMA interface matches your existing board or cable infrastructure.

Part Context

This part belongs to Pasternack's RF filter series, which includes various cutoff frequencies. Similar models like PE8720 and PE8725 offer different passbands within the same family. The PE8721 specifically targets the 2 GHz upper frequency limit.

Replacement Considerations

PE8720 offers a 1 GHz passband. PE8725 provides a 3 GHz passband. Both share the same five-section design and SMA female connectors. Verify frequency requirements before substituting.
