PE8739

Overview

The PE8739 is a six-section bandpass RF filter manufactured by Pasternack. It operates within a frequency range of 4.4 GHz to 4.95 GHz, providing a 550 MHz passband with a center frequency of 4.675 GHz. The module features SMA female connectors and exhibits an insertion loss of 1.25 dB. Designed for signal conditioning in radio frequency applications, it supports point-to-point and public safety bands.

Feature Summary

• Six-section bandpass architecture for enhanced signal filtering
• SMA female connector interface for standard integration
• Optimized for 4.4 GHz to 4.95 GHz operational range

Applications

• Point-to-point communication systems
• Public safety frequency bands
• Radio frequency signal conditioning

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer documentation may reference variant designations such as PE8739A. Confirm that the required SMA female connectors match your system interface requirements. Ensure the 550 MHz bandwidth aligns with your application's spectral needs before finalizing procurement.

Selection Notes

Select this component for applications requiring a fixed 550 MHz passband between 4.4 GHz and 4.95 GHz. The six-section design offers steep roll-off characteristics suitable for interference rejection. Verify that the 1.25 dB insertion loss meets your link budget constraints and that SMA connectors are compatible with existing cabling infrastructure.
