SF2316E-3

Overview

The SF2316E-3 is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 1.583 GHz with a bandwidth of 60 MHz, covering the range from 1.553 GHz to 1.613 GHz. The component features a maximum insertion loss of 2 dB and is designed for 50 Ohm impedance systems. It supports a rated voltage of 3 V and functions within an operating temperature range of -40°C to +85°C. The device is housed in a compact 6-SMD, no lead package and holds AEC-Q200 qualification for automotive reliability.

Feature Summary

• Utilizes Surface Acoustic Wave technology for high-performance signal conditioning
• AEC-Q200 qualified for automotive electronic applications
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• GPS receiver front-end filtering
• GNSS module signal integrity enhancement

Procurement Notes

Verify the specific suffix against official RFMi documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with the target assembly process regarding the 6-SMD footprint. Confirm that the 3V rating aligns with the system's power supply constraints. Cross-reference the AEC-Q200 certification status if the application requires strict automotive grade validation.

Selection Notes

Select this component when a narrow 60 MHz bandwidth is required around the 1.583 GHz L-band frequency. The low insertion loss characteristic makes it suitable for sensitive receiver chains where signal attenuation must be minimized. Consider the thermal stability provided by the SAW technology for environments experiencing significant temperature fluctuations.
