PE8725

Overview

The PE8725 is a five-section low-pass filter manufactured by Pasternack, designed for signal conditioning applications. It operates from DC to 3 GHz with a characteristic impedance of 50 Ohms. The device features SMA female connectors and maintains an insertion loss of 1 dB. It supports a maximum power handling capacity of 10 Watts and exhibits an input VSWR of 1.5:1. Constructed as a standalone RF module, it weighs approximately 6.427 grams.

Feature Summary

• Five-section low-pass filter design for effective harmonic suppression
• SMA female connectors for standard coaxial integration
• Operates across a frequency range from DC to 3 GHz

Applications

• RF signal conditioning in communication systems
• Harmonic filtering in test and measurement equipment
• Base station signal processing modules

Procurement Notes

Verify the specific connector gender and impedance requirements against system specifications before procurement. Confirm that the 10 Watt power rating aligns with operational limits. Ensure SMA compatibility with existing cabling infrastructure. Check for RoHS compliance documentation if required by regulatory standards. Validate the 50 Ohm impedance matches the transmission line characteristics.

Selection Notes

Select this component when a five-section topology is required for steep roll-off characteristics within the 3 GHz bandwidth. Consider the physical dimensions and weight constraints for enclosure integration. Evaluate the 1 dB insertion loss impact on overall system gain. Ensure the SMA interface suits the available connection hardware. Assess thermal management needs relative to the 10 Watt power handling capability.

Part Context

This part belongs to the Pasternack RF Coaxial Filters series, specifically categorized under Signal Conditioning products. It is distinct from higher-order filters or different impedance variants within the manufacturer's lineup. The five-section architecture provides a balance between attenuation performance and physical size compared to simpler designs.

Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement. Verify electrical parameters such as cutoff frequency, insertion loss, and power handling when evaluating alternative components. Ensure mechanical compatibility with existing mounting structures and connector interfaces.
