SF2316H-1

Overview

The RFMi SF2316H-1 is a surface-mount SAW bandpass filter designed for signal conditioning applications. It operates at a center frequency of 1.588655 GHz with a bandwidth of 4 MHz. The component features a 50 Ohm impedance and is rated for a maximum voltage of 3 V. It utilizes an SM-2016-4 package suitable for SMD/SMT mounting. The device supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Surface-mount SAW technology for compact integration
• High-frequency bandpass filtering capability
• Wide operational temperature tolerance

Applications

• GNSS receiver front-end filtering
• Satellite navigation systems
• Global positioning module signal conditioning

Procurement Notes

Verify the specific suffix designation, as variations exist within the SF2316 series. Confirm that the required center frequency matches exactly 1.588655 GHz rather than the standard 1.583 GHz variant. Ensure the SM-2016-4 footprint aligns with the PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a precise L1/L5 GNSS frequency response is required in a minimal footprint. Compare against the SF2316H model if a wider bandwidth or different center frequency is acceptable. Ensure the design accommodates the 3V rating and the specified thermal operating limits for the target environment.

Part Context

This part belongs to the RFMi SF series of surface acoustic wave filters. These components are engineered for high-performance radio frequency applications requiring stable frequency selection. The series offers various center frequencies tailored for global navigation satellite systems and wireless communication standards.

Replacement Considerations

The SF2316H is a related variant but operates at 1.583 GHz with a significantly wider bandwidth. Direct substitution requires verification of frequency alignment and bandwidth specifications to ensure system performance integrity.
