SF15751

Overview

The SF15751 is a bandpass cavity filter manufactured by Fairview Microwave, designed for radio frequency applications. It operates within a frequency range of 1.565 GHz to 1.585 GHz, centered at 1.575 GHz. The device features a bandwidth of 20 MHz and utilizes SMA female connectors for interface. Key electrical specifications include an insertion loss of 1.5 dB and minimum rejection levels of 55 dB at 1.45 GHz and 1.7 GHz. Constructed with a three-section combline filter design, it ensures stable signal filtering performance in RF systems.

Feature Summary

• Three-section combline filter design for effective signal processing
• High rejection capability at specified off-band frequencies
• Chassis mounting type for secure installation

Applications

• Radio frequency signal filtering
• Communication system interference suppression
• RF equipment signal conditioning

Procurement Notes

Verify the specific connector type and mounting requirements against your system design before procurement. Confirm that the operating frequency range aligns with your application needs. Check for RoHS compliance status if required by your regulatory standards. Ensure proper handling procedures are followed due to the precision nature of RF components.

Selection Notes

Select this component when a narrow bandpass filter is required around the 1.575 GHz center frequency. Consider the 20 MHz bandwidth and 1.5 dB insertion loss characteristics for system budget calculations. Evaluate the chassis mount option for integration into larger RF assemblies. Compare rejection specs at 1.45 GHz and 1.7 GHz against adjacent channel requirements.
