SF2405-SMA

Overview

The SF2405-SMA is a low-pass RF filter manufactured by Fairview Microwave, designed for signal conditioning applications. It operates from DC to 30 MHz with a 3 dB cutoff frequency at 30 MHz and provides a stopband range of 45 to 60 MHz. The device features SMA female connectors and exhibits an insertion loss of 1 dB. Constructed for reliable performance in radio frequency environments, it serves as a critical component for filtering unwanted high-frequency signals while preserving the integrity of lower frequency data.

Feature Summary

• Provides effective attenuation of frequencies above the designated passband
• Utilizes standard SMA female interface for straightforward integration
• Maintains signal integrity within the specified low-frequency range

Applications

• Radio frequency signal conditioning
• Low-frequency data transmission systems
• Electronic test and measurement equipment

Procurement Notes

Verify the specific connector gender and impedance requirements against system schematics before procurement. Confirm that the operating environment remains within the thermal limits defined in the official datasheet. Ensure compatibility with existing SMA mating hardware to prevent mechanical stress or signal degradation during installation.

Selection Notes

Select this component when a sharp transition between the 30 MHz passband and the 45 MHz stopband is required. Consider the 1 dB insertion loss impact on overall system gain. Evaluate physical space constraints relative to the package dimensions provided in the technical documentation to ensure proper fit within the assembly.

Part Context

Fairview Microwave specializes in custom and standard RF solutions, including filters, cables, and adapters. The SF2405-SMA belongs to their line of passive signal conditioning components, engineered to meet rigorous performance standards for industrial and commercial radio frequency applications requiring precise frequency management.

Replacement Considerations

Consult the manufacturer's official documentation for cross-reference information. Verify that any substitute part matches the 30 MHz cutoff, SMA interface, and 50 Ohm impedance specifications to maintain circuit functionality.
