SF2199E

Overview

The SF2199E is a Surface Acoustic Wave (SAW) bandpass filter manufactured by RFMi. It operates at a center frequency of 787 MHz with a bandwidth ranging from 776 MHz to 798 MHz. The component features a 50 Ohm impedance and an insertion loss of 2.4 dB. It is rated for a voltage of 3 V and functions within a temperature range of -40°C to +85°C. The device utilizes a 6-SMD, No Lead package in the SM-3030-6 form factor, suitable for board mount applications.

Feature Summary

• Surface Acoustic Wave technology for signal conditioning
• Bandpass filtering capability centered at 787 MHz
• Compact surface-mount design for space-constrained layouts

Applications

• General purpose RF applications
• Low power short distance communication systems

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Ensure the selected package variant matches the required PCB footprint dimensions. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a narrow bandpass filter is required around 787 MHz with low insertion loss. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Consider the SM-3030-6 package size for board space limitations. Verify thermal performance against the specified -40°C to +85°C operational range during system integration.
