SF2316E-1

Overview

The RFMi SF2316E-1 is a Surface Acoustic Wave (SAW) bandpass filter designed for signal conditioning applications. It operates at a center frequency of 1.582 GHz with a specified bandwidth of 51 MHz, covering a range from 1.56542 GHz to 1.59742 GHz. The component features a typical insertion loss of 1.8 dB and maintains a 50 Ohms impedance. Rated for 3 V, it utilizes an SM-3030-6 surface-mount package. The device is qualified under AEC-Q200 standards and functions within a temperature range of -45°C to +125°C.

Feature Summary

• AEC-Q200 automotive qualification ensures reliability in demanding environments.
• Compact SM-3030-6 surface-mount package facilitates automated board mounting.
• Low insertion loss characteristic supports efficient signal transmission.

Applications

• GNSS receiver front-end filtering
• Automotive telematics systems
• General purpose RF signal conditioning

Procurement Notes

Verify the specific datasheet revision against the manufacturing date code to ensure parameter consistency, as variations may exist between production batches. Confirm that the SM-3030-6 footprint matches the target PCB layout dimensions precisely. Ensure the operating environment remains within the specified -45°C to +125°C thermal limits to maintain AEC-Q200 compliance and electrical performance stability during deployment.

Selection Notes

Select this component when a narrowband SAW filter is required for L-band frequencies around 1.58 GHz. The AEC-Q200 rating makes it suitable for automotive electronics where long-term reliability is critical. Compare the 51 MHz bandwidth against system requirements to ensure adequate channel isolation. Consider the 1.8 dB insertion loss impact on overall link budget before finalizing the design integration.

Part Context

This part belongs to the RFMi SF series of SAW filters, which are engineered for high-frequency signal processing. The series typically includes variants optimized for different center frequencies and bandwidths. The SF2316E-1 specifically targets applications requiring precise filtering in the 1.5 GHz range, leveraging standard surface-mount technology for easy integration into compact electronic assemblies.

Replacement Considerations
