PE8704

Overview

The Pasternack PE8704 is a four-section bandpass RF filter module designed for precise signal conditioning within the L-band spectrum. It operates with a center frequency of 1.227 GHz and maintains a strict 20 MHz bandwidth, ensuring high selectivity for targeted applications. The unit features SMA female connectors for standard interface compatibility and exhibits a typical insertion loss of 1.3 dB, balancing signal integrity with attenuation requirements. Constructed as a robust module, it supports frequencies ranging from 1.217 GHz to 1.237 GHz, making it suitable for specialized communication systems requiring stable filtering performance in compact form factors.

Feature Summary

• Four-section bandpass architecture for enhanced spectral selectivity
• SMA female connector interfaces for standardized integration
• Narrow 20 MHz passband design for precise frequency isolation

Applications

• L-band communication systems requiring specific frequency filtering
• Test and measurement equipment needing stable bandpass characteristics
• Radio frequency signal conditioning modules

Procurement Notes

Verify the exact connector gender and mechanical dimensions against your system requirements before ordering. Confirm that the SMA female interface matches your mating hardware. Ensure the 1.227 GHz center frequency aligns with your operational bandwidth needs. Check for any specific environmental ratings if the deployment involves extreme conditions. Review the datasheet for mounting constraints and thermal management guidelines to ensure proper installation and long-term reliability.

Selection Notes

Select this component when a narrow 20 MHz bandwidth is critical for rejecting adjacent channel interference. The four-section design offers superior roll-off characteristics compared to simpler filters. Consider the 1.3 dB insertion loss impact on your overall link budget. Verify that the SMA female connection type fits your existing cabling infrastructure. This module is appropriate for applications prioritizing frequency precision over wideband coverage.

Part Context

This part belongs to Pasternack's line of RF filters, specifically engineered for signal conditioning tasks. It complements other bandpass and low-pass filter offerings by providing a specialized solution for the 1.2 GHz range. The product series focuses on delivering reliable performance in modular formats, supporting various industrial and commercial radio frequency applications where consistent filtering is required.

Replacement Considerations

Check for compatible substitutes with similar 20 MHz bandwidth and SMA female interfaces. Ensure replacement units maintain the 1.227 GHz center frequency to avoid signal degradation. Verify that alternative components offer comparable insertion loss specifications. Confirm mechanical compatibility for direct board or chassis integration without redesigning mounting structures.
