PE8720

Overview

The Pasternack PE8720 is a five-section lowpass filter designed for radio frequency applications. It operates from DC to 1,000 MHz with a 1,000 MHz passband. The component features SMA female connectors and maintains a 50 Ohm impedance. Key electrical specifications include a maximum insertion loss of 1 dB, an input maximum VSWR of 1.5:1, and a maximum power rating of 10 Watts.

Feature Summary

• Five-section lowpass filter architecture
• SMA female connector interface
• 50 Ohm system impedance

Applications

• RF signal conditioning
• Microwave circuit integration
• Frequency filtering in communication systems

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may be updated. Confirm that the SMA female connector type matches your system requirements. Ensure the 10 Watt power handling capacity is sufficient for your application environment. Cross-reference the 1,000 MHz passband specification against your operational frequency needs to ensure compatibility.

Selection Notes

Select this model if a 1,000 MHz cutoff frequency is required. Compare against the PE8721 (2 GHz) or PE8722 (225 MHz) if different bandwidths are needed. Verify that the 50 Ohm impedance aligns with your transmission line characteristics. Consider the physical size constraints associated with a five-section filter design.

Part Context

This component belongs to the Pasternack PE87xx series of lowpass filters. These devices share a common five-section topology and SMA female connector style. Variants within the series differ primarily by their specified passband frequencies, ranging from 30 MHz to 3 GHz. The series provides standardized RF filtering solutions for various microwave applications.

Replacement Considerations

Pasternack PE8721 offers a 2 GHz passband. Pasternack PE8722 provides a 225 MHz passband. Pasternack PE8723 supports up to 30 MHz. Pasternack PE8724 covers up to 300 MHz. Pasternack PE8725 extends to 3 GHz. All share similar connector types and section counts.
